Safety Instructions, Warnings, and Notes
2.Safety Instructions, Warnings, and Notes
EN 5LC4.9E AB2.
Index of this chapter:
2.1 Safety Instructions
2.2 Warnings
2.3 Notes
2.1Safety Instructions
Safety regulations require the following during a repair:
•Connect the set to the Mains (AC Power) via an isolation
transformer (> 800 VA).
•Replace safety components, indicated by the symbol h,
only by components identical to the original ones. Any
other component substitution (other than original type) may
increase risk of fire or electrical shock hazard.
Safety regulations require that after a repair, the set must be
returned in its original condition. Pay in particular attention to
the following points:
•Route the wire trees correctly and fix them with the
mounted cable clamps.
•Check the insulation of the Mains (AC Power) lead for
external damage.
•Check the strain relief of the Mains (AC Power) cord for
proper function.
•Check the electrical DC resistance between the Mains (AC
Power) plug and the secondary side (only for sets that have
a Mains (AC Power) isolated power supply):
1. Unplug the Mains (AC Power) cord and connect a wire
between the two pins of the Mains (AC Power) plug.
2. Set the Mains (AC Power) switch to the "on" position
(keep the Mains (AC Power) cord unplugged!).
3. Measure the resistance value between the pins of the
Mains (AC Power) plug and the metal shielding of the
tuner or the aerial connection on the set. The reading
should be between 4.5 Mohm and 12 Mohm.
4. Switch "off" the set, and remove the wire between the
two pins of the Mains (AC Power) plug.
•Check the cabinet for defects, to prevent touching of any
inner parts by the customer.
2.3Notes
2.3.1General
•Measure the voltages and waveforms with regard to the
chassis (= tuner) ground (H), or hot ground (I), depending
on the tested area of circuitry. The voltages and waveforms
shown in the diagrams are indicative. Measure them in the
Service Default Mode (see chapter 5) with a colour bar
signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated
otherwise) and picture carrier at 475.25 MHz for PAL, or
61.25 MHz for NTSC (channel 3).
•Where necessary, measure the waveforms and voltages
with (D) and without (E) aerial signal. Measure the
voltages in the power supply section both in normal
operation (G) and in stand-by (F). These values are
indicated by means of the appropriate symbols.
•The semiconductors indicated in the circuit diagram and in
the parts lists, are interchangeable per position with the
semiconductors in the unit, irrespective of the type
indication on these semiconductors.
2.3.2Schematic Notes
•All resistor values are in ohms, and the value multiplier is
often used to indicate the decimal point location (e.g. 2K2
indicates 2.2 kohm).
•Resistor values with no multiplier may be indicated with
either an "E" or an "R" (e.g. 220E or 220R indicates 220
ohm).
•All capacitor values are given in micro-farads (µ= x10
nano-farads (n= x10
•Capacitor values may also use the value multiplier as the
decimal point indication (e.g. 2p2 indicates 2.2 pF).
•An "asterisk" (*) indicates component usage varies. Refer
to the diversity tables for the correct values.
•The correct component values are listed in the Spare Parts
List. Therefore, always check this list when there is any
doubt.
-9
), or pico-farads (p= x10
-12
-6
),
).
2.2Warnings
•All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD w). Careless handling
during repair can reduce life drastically. Make sure that,
during repair, you are connected with the same potential as
the mass of the set by a wristband with resistance. Keep
components and tools also at this same potential. Available
ESD protection equipment:
– Complete kit ESD3 (small tablemat, wristband,
connection box, extension cable and earth cable) 4822
310 10671.
– Wristband tester 4822 344 13999.
•Be careful during measurements in the high voltage
section.
•Never replace modules or other components while the unit
is switched "on".
•When you align the set, use plastic rather than metal tools.
This will prevent any short circuits and the danger of a
circuit becoming unstable.
2.3.3Rework on BGA (Ball Grid Array) ICs
General
Although (LF)BGA assembly yields are very high, there may
still be a requirement for component rework. By rework, we
mean the process of removing the component from the PWB
and replacing it with a new component. If an (LF)BGA is
removed from a PWB, the solder balls of the component are
deformed drastically so the removed (LF)BGA has to be
discarded.
Device Removal
As is the case with any component that, is being removed, it is
essential when removing an (LF)BGA, that the board, tracks,
solder lands, or surrounding components are not damaged. To
remove an (LF)BGA, the board must be uniformly heated to a
temperature close to the reflow soldering temperature.
A uniform temperature reduces the risk of warping the PWB. To
do this, we recommend that the board is heated until it is certain
that all the joints are molten. Then carefully pull the component
off the board with a vacuum nozzle. For the appropriate
temperature profiles, see the IC data sheet.
Area Preparation
When the component has been removed, the vacant IC area
must be cleaned before replacing the (LF)BGA.
Removing an IC often leaves varying amounts of solder on the
mounting lands. This excessive solder can be removed with
either a solder sucker or solder wick. The remaining flux can be
removed with a brush and cleaning agent.
Page 6
EN 6LC4.9E AB2.
Safety Instructions, Warnings, and Notes
After the board is properly cleaned and inspected, apply flux on
the solder lands and on the connection balls of the (LF)BGA.
Note: Do not apply solder paste, as this has been shown to
result in problems during re-soldering.
Device Replacement
The last step in the repair process is to solder the new
component on the board. Ideally, the (LF)BGA should be
aligned under a microscope or magnifying glass. If this is not
possible, try to align the (LF)BGA with any board markers.
So as not to damage neighbouring components, it may be
necessary to reduce some temperatures and times.
More Information
For more information on how to handle BGA devices, visit this
URL: www.atyourservice.ce.philips.com (needs subscription,
not available for all regions). After login, select “Magazine”,
then go to “Workshop Information”. Here you will find
Information on how to deal with BGA-ICs.
2.3.4 Lead-free Solder
Philips CE is producing lead-free sets (PBF) from 1.1.2005
onwards.
Identification: The bottom line of a type plate gives a 14-digit
serial number. Digits 5 and 6 refer to the production year, digits
7 and 8 refer to production week (in example below it is 1991
week 18).
To avoid wear-out of tips, switch “off” unused equipment or
reduce heat.
•Mix of lead-free soldering tin/parts with leaded soldering
tin/parts is possible but PHILIPS recommends strongly to avoid mixed regimes. If this cannot be avoided, carefully
clear the solder-joint from old tin and re-solder with new tin.
•Use only original spare-parts listed in the Service-Manuals.
Not listed standard material (commodities) has to be
purchased at external companies.
•Special information for lead-free BGA ICs: these ICs will be
delivered in so-called "dry-packaging" to protect the IC
against moisture. This packaging may only be opened
shortly before it is used (soldered). Otherwise the body of
the IC gets "wet" inside and during the heating time the
structure of the IC will be destroyed due to high (steam-)
pressure inside the body. If the packaging was opened
before usage, the IC has to be heated up for some hours
(around 90°C) for drying (think of ESD-protection!).
Do not re-use BGAs at all!
•For sets produced before 1.1.2005, containing leaded
soldering tin and components, all needed spare parts will
be available till the end of the service period. For the repair
of such sets nothing changes.
In case of doubt whether the board is lead-free or not (or with
mixed technologies), you can use the following method:
•Always use the highest temperature to solder, when using
SAC305 (see also instructions below).
•De-solder thoroughly (clean solder joints to avoid the
mixing of two alloys).
E_06532_024.eps
230205
Figure 2-1 Serial number example
Regardless of the special lead-free logo (which is not always
indicated), one must treat all sets from this date onwards
according to the rules as described below.
P
b
Figure 2-2 Lead-free logo
Due to lead-free technology some rules have to be respected
by the workshop during a repair:
•Use only lead-free soldering tin Philips SAC305 with order
code 0622 149 00106. If lead-free solder paste is required,
please contact the manufacturer of your soldering
equipment. In general, use of solder paste within
workshops should be avoided because paste is not easy to
store and to handle.
•Use only adequate solder tools applicable for lead-free
soldering tin. The solder tool must be able:
– To reach a solder-tip temperature of at least 400°C.
– To stabilise the adjusted temperature at the solder-tip.
– To exchange solder-tips for different applications.
•Adjust your solder tool so that a temperature of around
360°C - 380°C is reached and stabilised at the solder joint.
Heating time of the solder-joint should not exceed ~ 4 sec.
Avoid temperatures above 400°C, otherwise wear-out of
tips will increase drastically and flux-fluid will be destroyed.
Caution: For BGA-ICs, you must use the correct temperature
profile, which is coupled to the 12NC. For an overview of these
profiles, visit the website www.atyourservice.ce.philips.com
(needs subscription, but is not available for all regions).
You will find this and more technical information within the
"Magazine", chapter "Workshop information".
For additional questions please contact your local repair help
desk.
2.3.5Practical Service Precautions
•It makes sense to avoid exposure to electrical shock.
While some sources are expected to have a possible
dangerous impact, others of quite high potential are of
limited current and are sometimes held in less regard.
•Always respect voltages. While some may not be
dangerous in themselves, they can cause unexpected
reactions that are best avoided. Before reaching into a
powered TV set, it is best to test the high voltage insulation.
It is easy to do, and is a good service precaution.

3.Directions for Use
You can download this information from the following websites:
•Figures below can deviate slightly from the actual situation,
due to the different set executions.
•Follow the disassembling instructions in described order.
4.2Service Positions
For easy servicing of this set, there are a few possibilities
created:
•The buffers from the packaging (see figure "Rear cover").
•Foam bars (created for service).
•Aluminium service stands (created for Service).
4.2.1Foam Bars

F_15660_007.eps
280705
The foam bars (order code 3122 785 90580 for two pieces) can
be used for all types and sizes of Flat TVs. By laying the TV
face down on the (ESD protective) foam bars, a stable situation
is created to perform measurements and alignments.
By placing a mirror under the TV, you can monitor the screen.
4.2.2Aluminium Stands
E_06532_019.eps
170504
Figure 4-3 Aluminium stands (drawing of MkI)
Page 9
The aluminium stands (order code 3122 785 90480) can be
mounted with the back cover removed or still left on. So, the
stand can be used to store products or to do measurements. It
is also very suitable to perform duration tests without taking
much space, without having the risk of overheating, or the risk
of products falling. The stands can be mounted and removed
quick and easy with use of the delivered screws that can be
tightened and loosened manually without the use of tools. See
figure above.
Note: Only use the delivered screws to mount the monitor to
the stands.

Specifications
ComPair consists of a Windows based fault finding program
and an interface box between PC and the (defective) product.
The ComPair interface box is connected to the PC via a serial
(or RS-232) cable.
For this chassis, the ComPair interface box and the TV
communicate via a bi-directional service cable via the service
connector(s).
The ComPair faultfinding program is able to determine the
problem of the defective television. ComPair can gather
diagnostic information in two ways:
•Automatically (by communicating with the television):
ComPair can automatically read out the contents of the
entire error buffer. Diagnosis is done on I
ComPair can access the I
ComPair can send and receive I

C/UART level.
C/UART commands to
the microcontroller of the television. In this way, it is
possible for ComPair to communicate (read and write) to
devices on the I
2
C/UART buses of the TV-set.
•Manually (by asking questions to you): Automatic
diagnosis is only possible if the microcontroller of the
television is working correctly and only to a certain extent.
When this is not the case, ComPair will guide you through
the faultfinding tree by asking you questions (e.g. Does the
screen give a picture? Click on the correct answer: YES /
NO) and showing you examples (e.g. Measure test-point I7
and click on the correct oscillogram you see on the
oscilloscope). You can answer by clicking on a link (e.g.
text or a waveform picture) that will bring you to the next
step in the faultfinding process.
By a combination of automatic diagnostics and an interactive
question / answer procedure, ComPair will enable you to find
most problems in a fast and effective way.
How To Connect
This is described in the chassis faultfinding database in
ComPair.
Caution: It is compulsory to connect the TV to the PC as
shown in the picture below (with the ComPair interface in
between), as the ComPair interface acts as a level shifter. If
one connects the TV directly to the PC (via UART), ICs will be
blown!

5.4Service Tools
5.4.1 ComPair
Introduction
ComPair (Computer Aided Repair) is a service tool for Philips
Consumer Electronics products. ComPair is a further
development on the European DST (service remote control),
which allows faster and more accurate diagnostics. ComPair
has three big advantages:
1. ComPair helps you to quickly get an understanding on how
to repair the chassis in a short time by guiding you
systematically through the repair procedures.
2. ComPair allows very detailed diagnostics (on I
is therefore capable of accurately indicating problem areas.
You do not have to know anything about I
yourself because ComPair takes care of this.
3. ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the
microprocessor is working) and all repair information is
directly available. When ComPair is installed together with
the Force/SearchMan electronic manual of the defective
chassis, schematics and PWBs are only a mouse click
away.
Note: If you encounter any problems, contact your local
support desk.
5.4.2LVDS Tool
Introduction
This service tool (also called “ComPair Assistant 1“) may help
you to identify, in case the TV does not show any picture,
whether the Small Signal Board (SSB) or the display of a Flat
TV is defective.
Furthermore it is possible to program EPLDs with this tool
(Byteblaster). Read the user manual for an explanation of this
feature.
Since 2004, the LVDS output connectors in our Flat TV models
are standardised (with some exceptions). With the two
delivered LVDS interface cables (31p and 20p) you can cover
most chassis (in special cases, an extra cable will be offered).
When operating, the tool will show a small (scaled) picture on
a VGA monitor. Due to a limited memory capacity, it is not
possible to increase the size when processing high-resolution
LVDS signals (>= 1280x768). Generally this tool is intended to
determine if the SSB is working or not. Thus to determine if
LVDS, RGB, and sync signals are okay.
How to Connect
Connections are explained in the user manual, which is
delivered with the tool.
Note: To use the LVDS tool, you must have ComPair release
2004-1 (or later) on your PC (engine version >= 2.2.05).
For every TV type number and screen size, one must choose
the proper settings via ComPair. The ComPair file will be
updated regularly with new introduced chassis information.
How to Order
•LVDS tool (incl. two LVDS cables: 31p and 20p):
3122 785 90671.
•LVDS cable 41p-to-31p for CA1 (dual -> single LVDS):
3122 785 90830.
5.5Error Codes
The error code buffer contains all errors detected since the last
time the buffer was erased. The buffer is written from left to
right. When an error occurs that is not yet in the error code
buffer, it is displayed at the left side and all other errors shift one
position to the right.
5.5.1How to Read the Error Buffer
You can read the error buffer in 3 ways:
•On screen via the SAM (if you have a picture).
Examples:
– ERROR: 0 0 0 0 0 : No errors detected
– ERROR: 6 0 0 0 0 : Error code 6 is the last and only
detected error
– ERROR: 9 6 0 0 0 : Error code 6 was detected first and
error code 9 is the last detected (newest) error
•Via the blinking LED procedure (when you have no
picture). See “The Blinking LED Procedure”.
•Via ComPair.
5.5.2How to Clear the Error Buffer
The error code buffer is cleared in the following cases:
•By using the CLEAR command in the SAM menu:
– To enter SAM, press the following key sequence on the
remote control transmitter: “062596” directly followed
by the OSD/STATUS button (do not allow the display
to time out between entries while keying the
sequence).
– Make sure the menu item CLEAR is highlighted. Use
the MENU UP/DOWN buttons, if necessary.
– Press the MENU RIGHT button to clear the error
buffer. The text on the right side of the “CLEAR” line will
change from “CLEAR?” to “CLEARED”
•If the contents of the error buffer have not changed for 50
hours, the error buffer resets automatically.
Note: If you exit SAM by disconnecting the mains from the
television set, the error buffer is not reset.
5.5.3 Error Codes
In case of non-intermittent faults, write down the errors present
in the error buffer and clear the error buffer before you begin
the repair. This ensures that old error codes are no longer
present.
If possible, check the entire contents of the error buffer. In
some situations, an error code is only the result of another error
and not the actual cause of the problem (for example, a fault in
the protection detection circuitry can also lead to a protection).

5.6The Blinking LED Procedure
Using this procedure, you can make the contents of the error
buffer visible via the front LED. This is especially useful when
there is no picture.
When the SDM is entered, the front LED will blink the contents
of the error-buffer:
•The LED blinks with as many pulses as the error code
number, followed by a time period of 1.5 seconds, in which
the LED is off.
•Then this sequence is repeated.
Any RC5 command terminates this sequence.
Example of error buffer: 12 9 6 0 0
After entering SDM, the following occurs:
•1 long blink of 5 seconds to start the sequence,
•12 short blinks followed by a pause of 1.5 seconds,
•9 short blinks followed by a pause of 1.5 seconds,
•6 short blinks followed by a pause of 1.5 seconds,
•1 long blink of 1.5 seconds to finish the sequence,
•The sequence starts again with 12 short blinks.
5.7Fault Finding and Repair Tips
Notes:
•It is assumed that the components are mounted correctly
with correct values and no bad solder joints.
•Before any fault finding actions, check if the correct options
are set.
5.7.1NVM Editor
In some cases, it can be handy if one directly can change the
NVM contents. This can be done with the “NVM Editor” in SAM
mode. With this option, single bytes can be changed.
Caution:
•Do not change the NVM settings without
understanding the function of each setting, because
incorrect NVM settings may seriously hamper the
correct functioning of the TV set!
•Do not change the Scaler NVM settings, as this will
hamper the DVI functionality of the TV set!
•Always note down the existing NVM settings, before
changing the settings. This will enable you to return to the
orgininal settings, if the new settings turn out to be
incorrect.

(For empty NVM replacement, short the SDM with a jumper
and apply the mains voltage. Remember to remove the jumper
after the reload is completed). After the default values are
downloaded, it will be possible to start up and to start aligning
the TV set. This is no longer initiated automatically; to initiate
the download the following action has to be performed:
1. Switch “off” the TV set by disconnecting the AC Power
2. Short circuit the SDM jumpers (keep short-circuited).
3. Press P+ or Ch+ on the local keyboard (and keep it
4. Switch on the TV set via the AC Power plug.
5. Keep pressing the P+/Ch+ button until the set has started
Alternative method:
1. Go to SAM.
2. Select NVM Editor (not SC NVM Editor).
3. Select ADR (address) to 1 (dec).
4. Change the VAL (value) to 170 (dec).
5. Store the value.
6. Disconnect the mains plug and wait for a few seconds.
7. Reconnect the mains plug and wait until the set goes into
No Picture in RF Mode, but there is a Noise Raster
1. Check whether picture is present in AV. If not, go to Video
processing troubleshooting section.
2. If present, check if the Option settings are correct.
3. Check if all the supply voltages are present (3.3/5/8/12/33
V).
4. Check if the I
5. Manually store a known channel and check if there is IF
output at Tuner pin 11.
6. Check the tuning DC voltage at pin 2 of the Tuner. The DC
voltage should vary according to the frequency/channel
being chosen.
7. If the tuning voltage is OK, check the tuner output, pin 11.
8. If it has no output, the Tuner may have a defect. Change
the Tuner.
Sound in Picture Problem for L' System (rolling horizontal
lines)
1. Check whether AGC L' in SAM mode is set to 0.
2. If yes, align the set to correct value.
Required System is not Selected Correctly
Check whether a Service jumper (#4204 & 4205, 0805 size) is
present. If yes, remove it.
2
C lines are working correctly (3.3 V).

EN 20LC4.9E AB5.
5.7.4Video Processing
No Power
1. Check +12 V and 3V3 at position 1J02.
2. If no supply, check the connector 1J02.
3. If it is correct, check the power supply board.
Power Supply is Correct, but no Green LED
1. Check if the connectors 1K00 are properly inserted.
2. If they are inserted correctly, check if the 3V3 is present.
No Picture Display (blank screen with correct sound
output)
1. Check whether the user menu is visible.
2. If the user menu is OK, activate teletext mode.
3. If teletext is OK, the problem is in the ADC (B18) &
Columbus 3D combfilter (B19), if present (depending on
model, see also paragraph “Teletext Path” in chapter 9).
4. If the user menu is not visible, check if the LCD panel
backlight is ON.
5. If the backlight is OFF, the problem is in the power supply
board or LCD panel. Also check pin 12 (LAMP_ON_OFF)
of 1J02. It should be HIGH during normal operation.
Note: For faultfinding purposes, it is important to know the
following: in Pixel Plus and Digital Crystal Clear models, which
have an ADC (B18) and Columbus 3D combfilter (B19), the
digital input of the scaler is used for the digital video path
(Hercules output), whereas the analogue RGB input (analogue
input of the scaler) is only used for teletext. This means that no
mixed mode (video plus teletext simultaneously) is possible. If
there is sound and teletext, but no video and user menu (blank
screen), the digital path (Hercules - ADC - Columbus - Scaler)
is faulty. If there is sound but no teletext, the back-end part
(Scaler - LCD panel) is faulty. In Crystal Clear models, which
do not have an ADC and Columbus, the RGB path (analogue
input of scaler) is used for both video and teletext.
Service Modes, Error Codes, and Fault Finding
No TV, but PC is Present
1. Check if Hsync_SDTV and Vsync_SDTV are present at pin
1 & pin13 of 7E03.
2. If they are present, check teletext output.
3. If there is no teletext output, the IC TDA150xx may be
defect.
5.7.5Power Supply
In case the power supply does not work, check (apart from the
obvious fuse-check) if the oscillators in IC7001 and IC7U01 are
working. If not, replace the ICs.

situation, due to the different set executions.
General: The Service Default Mode (SDM) and Service
Alignment Mode (SAM) are described in chapter 5. Menu
navigation is done with the Cursor Up, Down, Left or Right keys
of the remote control transmitter.
8.1General Alignment Conditions
Perform all electrical adjustments under the following
conditions:
Mains voltage and frequency: 100-240 V / 50/60 Hz.
Allow the set to warm up for approximately 10 minutes.
Test probe: Ri > 10 MΩ; Ci < 2.5 pF.

There are no hardware alignments foreseen for the plasma-TV.
8.3Software Alignments
With the software alignments of the Service Alignment Mode
(SAM) the geometry, white tone and tuner (IF) can be aligned.
To store the data: Use the RC button Menu to switch to the
main menu and next, switch to ‘Stand-by’ mode.

8.3.4ADC Gain and Grey Scale Alignment
The table below shows a number of NVM settings used for
each model of TV set. Be sure to use the correct editor in the
SAM menu (NVM Editor or SC NVM Editor), because the first
one is used for the Hercules NVM, and the second one for the
SCALER (SC) part of the TV set. For further important NVM
settings, see also the other NVM tables elsewhere in this
manual.
Caution:
•Do not change the NVM settings without
understanding the function of each setting, because
incorrect NVM settings may seriously hamper the
correct functioning of the TV set!
•Do not change the Scaler NVM settings, as this will
hamper the DVI functionality of the TV set!
•Always note down the existing NVM settings, before
changing the settings. This will enable you to return to the
orgininal settings, if the new settings turn out to be
incorrect.
Table 8-1 ADC gain and grey scale alignment
SDTV ADC Gain settings: Use the NVM Editor in SAM to set these
Options OP1...OP7 in the SAM menu can be used for quickly
restoring 64 features or settings of the HERCULES part of the
TV set to their orginal default factory values (8 groups of 8
features/settings each). When the decimal value of one option
byte OP1...OP7 is changed (see the first table below) then a
group of 8 bits, representing 8 HERCULES options or features,
is changed as well (see the second table below for a detailed
description of the features or settings that are changed).
The second table shows which option byte (OP1...OP7)
represents which group of 8 option bits. Each bit (0...7)
switches a particular HERCULES feature or setting ON or OFF,
depending on its value (1 or 0).
It is also possible to change the features or settings mentioned
in the second table directly at bit level, by means of the NVM
Editor in the SAM menu. In the NVM Editor, first the correct
NVM address (ADR) has to be entered, then the correct value
(VAL, 1 or 0) for each bit (see second table), and finally the
settings have to be stored (STORE). For quickly restoring the
HERCULES part of the TV set to its original factory settings,
however, it is more convenient to simply enter the default
factory settings OP1...OP7 that are given in the first table
below. How to do this, is described in the next paragraph.
How to Change an Option Byte
As has been explained above, an Option byte (OP) represents
a number of different HERCULES options. Changing these
bytes directly makes it possible to set all HERCULES options
very fast. All options are controlled via seven option bytes.
Select the option byte (OP1.. OP7) with the Menu Up/ Down
keys, and enter the new (decimal) value. For the correct
Factory Default settings, see the first table below. For more
detailed information, see the second table.
Leaving the Option submenu saves the changes in the Option
Byte settings. Some changes will only take effect after the set
has been switched “off” and “on” with the AC power switch (cold
start).
Table 8-2 Option codes OP1...OP7
Option table for quickly restoring the HERCULES to its
If you wish to know which features or settings of the
HERCULES are changed via OP1...OP7, or if you want to
change each option or feature bit by bit, use the more detailed
table below.
Note: the table below contains only part of the NVM settings
that can be changed. A second range of settings and features
can be found in Chapter 5 of this manual, in table NVM Default values. The settings mentioned there can only be changed via
the NVM editor. For further settings, see also the table “ADC
Gain and Grey scale alignment” elsewhere in this manual.

9.4PNx83xx MOJO
The MOJO is a source decoder chip targeted for very low cost
application in integrated digital televisions.The device contains
all hardware and software to be able to decode and display
MPEG2 transport streams, including:
•Descrambling
•Demultiplexing
•Audio / video decompression
•Video encoding.
•Overlay graphics provisions
Some features of the MOJO are:
•32-bit PR1910 core operating at 120 MHz.
•16-bit memory and peripheral interface to connect ROM,
NOR Flash and various peripherals.
•Sixteen external interrupt inputs shared with PIO lines.
•Several embedded peripheral units with physical interfaces
to:
– Two UART (RS-232) data ports
–Two I
– Two smart-card reader interfaces
– One Integrated Conditional Access Module interface
•Supports parallel and serial transport stream input
interfaces
2
C master / slave transceivers
9.5Front End
The front end of the “IBO Zapper” module is almost identical to
the “IBO+” module as used in the A10E with the exception that
the Transport Streams that come from the COFDM
demodulator are now fed through the PCMCIA controller first.
The PCMCIA controller receives encrypted Transport Streams
from the COFDM demodulator. Via the PCMCIA card, these
encrypted Transport Streams are decrypted, and transported
to the MOJO.
9.6Back End
The MOJO is the main building block of the back-end of the
“IBO Zapper” module. The IC decodes the MPEG-2 stream into
analogue video and digital audio.
9.6.1Transport Stream Input
The Transport Stream input is according to MPEG2 standard.
In the “IBO Zapper”, only 8-bit parallel is supported. The used
TS names are TDA_DATA.
9.6.2Video Outputs
The MOJO has two analogue video outputs:
•Primary (TV): YUV + RGB
•Secundary (VCR): CVBS
The primary MOJO output is used as input for the TV display
and is fed either to the Hercules YUV/RGB input (pins 78/79/
80), for teletext insertion purposes, or directly to the analogue
Scaler input D2/C2/B2. The signal path is as follows:
switch 7G09 chooses between the SCART1 input signal and
the YUV/RGB output of the MOJO. The signal selected by
switch 7G09 is passed on to one group of the inputs of switch
7E00. The other group of inputs of this switch is connected to
the three analogue input pins of the DVI-D connector. The
output signal of switch 7E00 is passed on to the Hercules input,
pins 78/79/80 and to the Scaler input D2/C2/B2 via switch 7E01
in the MUX-SYNC interface. This switch chooses between the
MOJO output signal and the Hercules output signal, which is
used for SDTV signals (analogue terrestrial TV reception via
the analogue receiving part). The Hercules output is not only
used for SDTV signals, but also for MOJO output signals that
were first sent to the Hercules input for e.g. teletext reinsertion
purposes before they are passed on to the Scaler.
The secundary MOJO output, which delivers CVBS signals, is
used for monitoring purposes or for recording via the SCART 2
output of the TV set. The signal path of the secundary MOJO
output is as follows:
the CVBS/VCR signal coming from the MOJO is sent to the
Hercules video switch input, pin 58, via switch 7G07. The
signal then appears on one of the outputs of the Hercules video
switch, pin 48, and is passed on via switches 7219 and 7G10
to pin 19 of SCART 2, which is the CVBS/monitor output.
For further details, see the manuals of the original TV sets on
which the various models of IBO zappers are based.
9.6.3 Audio Outputs
The MOJO has two audio output interfaces:
•SPDIF Out: The SPDIF sound output goes directly to a
connector on the back of the module.
•I2S Out: This digital sound output is fed through a DAC and
the analogue L/R signals are directely fed into the
Hercules.
9.7IBOLink Interface
The IBOLink™ approach is such that the conventional TV
microcontroller is re-used when digital functionality is added. In
principle, the TV can still operate without the bolt-on module.
The IBOLink™ software is added to the TV-set software, and is
operating as a software bridge.
9.8Control Interface
The “IBO Zapper” is connected as a slave I2C device, The I2C
bus should be +5V tolerable and operating at 100kHz(MAX).
The “IBO Zapper” module slave address is 0xE4 (similar to
IBO+) but is configurable via IBOLink.
All communication from digital module to Television chassis
has to be initiated via an active low hardware interrupt line from
the digital module.
9.9UART Interface
The UART interfaces (Universal Asynchronous Receiver And
Transmitter) are serial interfaces, which are used to transfer
data and commands between two devices.
The “IBO Zapper” system uses an UART interface for serial
communication with a pc for:
•Diagnostic SW for Service or Production
•SW uploading for Service or Development
9.10 Power Supply IBO Zapper Module
The “IBO Zapper” module operates from a single 12V supply
provided by the TV chassis. All other voltages that the module
needs are derived from the +12V. The module has four
different physical power states:
•“Off” State.
•“Passive Standby”.
•“Active Standby”.
•“On” State.
9.10.1 Off State
The set is powered off via the main power switch. The module
is not powered.

EN 87LC4.9E AB9.
9.10.2 Passive Standby State
The set is in standby mode. The module is in off state.
9.10.3 Active Standby State
The set is in “Semi-Standby” mode. All the circuits in the set,
except the audio output and the LCD display are powered up
and fully active. The set appears to be in normal standby mode
for the customer.
The module is in “On” or “Logical Standby” state.
•On state. In this state the module can perform the following
pre-programmed functions:
– VCR (digital program) records
– EPG updates
– Over-the-air software download signaling detection
and software downloads
•Logial Standby state. In this state only over-the-air
software download signaling detection and software
downloads can be performed.
9.10.4 On State
The set is fully functional and the module is powered up. The
module is in “On” or “Logical Standby” state.
•On state. In this state all system functionality is available or
the module is in software downloading process.
•Logial Standby state. In this state only over-the-air
software download signaling detection and software
downloads can be performed.
