Safety Instructions, Warnings, and Notes
2.Safety Instructions, Warnings, and Notes
EN 5TPT1.1HA LA2.
Index of this chapter:
1.1 Technical Specifications
1.2 Connections
1.3 Chassis Overview
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.
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.
•Manufactured under license from Dolby Laboratories.
“Dolby”, “Pro Logic” and the “double-D symbol”, are
trademarks of Dolby Laboratories.
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=×10
nano-farads (n= ×10-9), or pico-farads (p= ×10
•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.
2.3.3BGA (Ball Grid Array) ICs
Introduction
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 “Repair downloads”. Here you will find Information
on how to deal with BGA-ICs.

),
).
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.
2.3Notes
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
BGA Temperature Profiles
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 “Repair downloads”.
For additional questions please contact your local repair help
desk.
2.3.4Lead-free Soldering
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 stabilize 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 stabilized 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.
Page 6
江南家电维修论坛会员专用!http://bbs.520101.com
EN 6TPT1.1HA LA3.
Directions for Use
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.
2.3.5Alternative BOM identification
The third digit in the serial number (example:
AG2B0335000001) indicates the number of the alternative
B.O.M. (Bill Of Materials) that has been used for producing the
specific TV set. In general, it is possible that the same TV
model on the market is produced with e.g. two different types
of displays, coming from two different suppliers. This will then
result in sets which have the same CTN (Commercial Type
Number; e.g. 28PW9515/12) but which have a different B.O.M.
number.
By looking at the third digit of the serial number, one can
identify which B.O.M. is used for the TV set he is working with.
If the third digit of the serial number contains the number “1”
(example: AG1B033500001), then the TV set has been
manufactured according to B.O.M. number 1. If the third digit is
a “2” (example: AG2B0335000001), then the set has been
produced according to B.O.M. no. 2. This is important for
ordering the correct spare parts!
For the third digit, the numbers 1...9 and the characters A...Z
can be used, so in total: 9 plus 26= 35 different B.O.M.s can be
indicated by the third digit of the serial number.
Identification: The bottom line of a type plate gives a 14-digit
serial number. Digits 1 and 2 refer to the production centre (e.g.
AG is Bruges), digit 3 refers to the B.O.M. code, digit 4 refers
to the Service version change code, digits 5 and 6 refer to the
production year, and digits 7 and 8 refer to production week (in
example below it is 2006 week 17). The 6 last digits contain the
serial number.

2.3.6Board Level Repair (BLR) or Component Level Repair
(CLR)
If a board is defective, consult your repair procedure to decide
if the board has to be exchanged or if it should be repaired on
component level.
If your repair procedure says the board should be exchanged
completely, do not solder on the defective board. Otherwise, it
cannot be returned to the O.E.M. supplier for back charging!
2.3.7Practical Service Precautions
•It makes sense to avoid exposure to electrical shock.
•Always respect voltages. While some may not be

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.
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.

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).
4.2.1Foam Bars
The foam bars (order code 3122 785 90580 for two pieces) can
be used for all types and sizes of Flat TVs. See figure “Foam
bars” for details. Sets with a display of 42" and larger, require
four foam bars [1]. Ensure that the foam bars are always
supporting the cabinet and never only the display. Caution:
Failure to follow these guidelines can seriously damage the
display!
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.

Service Modes, Error Codes, and Fault Finding
5.Service Modes, Error Codes, and Fault Finding
EN 15TPT1.1HA LA5.
Index of this chapter:
5.1 Service Modes
5.2 Repair Flow Chart
5.3 Software Upgrading
5.1Service Modes
The Customer Service Mode (CSM) is used for communication
between the call centre and the customer, while the Factory
Mode offers several features for the service technician.
This chassis also offers the option of using ComPair, a
hardware interface between a computer and the TV chassis. It
offers the abilities of structured troubleshooting, error code
reading, and software version read-out for all chassis.
Minimum requirements for ComPair: a Pentium processor, a
Windows OS, and a CD-ROM drive (see also paragraph
“ComPair”).
5.1.1TV mode Switching
The iTV set can be switched between “iTV” and “normal TV”
mode (or vice versa) with the iTV setup remote RC2573/01.
To do this; press 024995 <M> (M=menu). Follow the message
shown on the screen.
5.1.2Customer Service Mode (CSM)
Purpose
The Customer Service Mode shows error codes and
information on the TV’s operation settings. The call centre can
instruct the customer (by telephone) to enter CSM in order to
identify the status of the set. This helps the call centre to
diagnose problems and failures in the TV set before making a
service call.
The CSM is a read-only mode; therefore, modifications are not
possible in this mode.
How to enter
To enter CSM, press the following key sequence on the remote
control transmitter: “123654” (do not allow the OSD display to
time out between entries while keying the sequence).
Upon entering the Customer Service Mode, the following
screen will appear:
2. Displays the production code.
3. Displays the software version in from the main processor
4. Displays the software version of the optional other
processor.
5. Code 1 displays the last 5 logged errors.
6. Code 2 displays the first 5 logged errors.
7. Displays the validiti of the HDMI HDCP key.
8. Displays the NVM version.
Error Codes
The error code buffer contains all defected errors since the last
time the buffer was erased. The buffer is written from left to
right, new errors are logged at the left side, and all other errors
shift one position to the right. When an error occurs, it is added
to the list of errors, provided the list is not full. When an error
occurs and the error buffer is full, then the new error is not
added, and the error buffer stays intact (history is maintained),
except when the error is a protection error. To prevent that an
occasional error stays in the list forever, the error is removed
from the list after more than 50 hours of operation. When
multiple errors occur (errors occurred within a short time span),
there is a high probability that there is some relation between
them.

5.3Software Upgrading
5.3.1Compair Service Tool
Introduction
ComPair (Computer Aided Repair) is a Service tool for Philips
Consumer Electronics products. and offers the following:
1. ComPair helps you to quickly get an understanding on how
to repair the chassis in a short and effective way.
2. ComPair allows very detailed diagnostics and is therefore
capable of accurately indicating problem areas. You do not
have to know anything about I2C or UART commands
yourself, because ComPair takes care of this.
3. ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the uP
is working) and all repair information is directly available.
4. ComPair features TV software up possibilities.
Specifications
ComPair consists of a Windows based fault finding program
and an interface box between PC and the (defective) product.
The (new) ComPair II interface box is connected to the PC via
an USB cable. For the TV chassis, the ComPair interface box
and the TV communicate via a bi-directional cable via the
service connector(s).

Caution: It is compulsory to connect the TV to the PC as
shown in the picture above (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!
The Service Modes 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:
•Power supply voltage (depends on region):
– AP-NTSC: 120 V
– AP-PAL-multi: 120 - 230 VAC / 50 Hz (± 10%).
– EU: 230 VAC / 50 Hz (± 10%).
– LATAM-NTSC: 120 - 230 V
– US: 120 V
•Connect the set to the mains via an isolation transformer
with low internal resistance.
•Allow the set to warm up for approximately 15 minutes.
•Measure voltages and waveforms in relation to correct
ground (e.g. measure audio signals in relation to
AUDIO_GND).
Caution: It is not allowed to use heatsinks as ground.
•Test probe: Ri > 10 Mohm, Ci < 20 pF.
•Use an isolated trimmer/screwdriver to perform
alignments.

8.2Hardware Alignments
There are no hardware alignments foreseen for this chassis.
8.3Software Alignments
With the software alignments of the Service Alignment Mode
(SAM) the Tuner and RGB settings 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.
correct x, y coordinates (see table “White D alignment
values”). Tolerance: dx: ± 0.004, dy: ± 0.004.
•Repeat this step for the other colour Temperatures that
need to be aligned.
•When finished return to the SAM root menu and press
STANDBY on the RC to store the aligned values to the
NVM.
Table 8-1 White D alignment values
ValueCool (11000 K)Normal (9000 K)Warm (6500 K)
x0.2780.2890.314
y0.2780.2910.319
If you do not have a colour analyser, you can use the default
values. This is the next best solution. The default values are
average values coming from production (statistics).
•Set the RED, GREEN and BLUE default values per
temperature according to the values in the “Tint settings”
table.
•When finished return to the SAM root menu and press
STANDBY on the RC to store the aligned values to the
NVM.
Table 8-2 Tint settings
Colour Temp.RGB
Cool243256249
Normal251256220
Warm256241189
Black Level Offset Alignment
•Activate SAM.
•Select “RGB Align.” -> “BlackL Offset” and choose a colour.
•Set all “BlackL Offset” values to “0”.
•When finished return to the SAM root menu and press
STANDBY on the RC to store the aligned values to the
NVM.
Note: For models with “Pixel Plus”, the “Black Offset” (black
level offset) should NOT be changed in SAM. These offset
values of RGB should be set to “0”, and should NOT be
adjusted. Any adjustment of these values will affect the low
light white balance.
8.3.1RGB Alignment
Before alignment, choose “TV MENU” -> “Picture” and set:
•“Brightness” to “50”.
•“Colour” to “50”.
•“Contrast” to “100”.
White Tone Alignment:
•Activate SAM.
•Select “RGB Align.” -> “White Tone” and choose a colour
temperature.
•Use a 100% white screen as input signal and set the
following values:
– All “White point” values initial to “256”.
– All “BlackL Offset” values to “0”.
In case you have a colour analyser:
•Measure with a calibrated (phosphor- independent) colour
analyser (e.g. Minolta CA-210) in the centre of the screen.
Consequently, the measurement needs to be done in a
dark environment.
•Adjust the correct x, y coordinates (while holding one of the
White point registers R, G or B on “256”) by means of
decreasing the value of one or two other white points to the
ADC YPbPr Gray Scale Alignment
When the grey scale is not correct, use this alignment:
•Activate SAM.
•Select “NVM Editor”.
•Enter address “26(dec)” (ADR).
•Set value (VAL) to “197(dec) ± 25".
•Store (STORE) the value.

9.1Introduction
This monitor uses a 1366 × 768 WXGA panel. It supports PC
analogue and DVI (HDMI port) digital inputs up to 1360 × 768
60 Hz mode, and Y/C and CVBS. Also YPbPr signal inputs
from SDTV to HDTV (480i, 480p, 720p, 1080i and 576i, 576p,
720p, 1080i) digital port for HDMI (480iW, 576iW, 480p, 576p,
480pW, 576pW, 720p 50/60 Hz, 1080i 50/60 Hz).
This F3 platform (development name) uses a Trident
SVP-PX66 Scaler IC, which has an embedded ADC for HDTV/
Analog D-sub input up to 108 MHz/10bit, a digital port for
CVBS and Y/C input, a TXT decoder, and a built-in dual 8/
10-bit LVDS transmitter. It uses Trident SVP-PX66 as scaler
engine, which has embedded Analog D-SUB, digital HDMI
receiver, scaling input signal to panel OSD mapping and simple
3D de-interlacer. The extra DDR is to accomplish video frame
rate conversion and to provide OSD and de-interlacer with
enough memory. The video processing and some audio
functions is done on the Scaler board.
The CPU (M30620SPGP) provides control signals such as
backlight control, RC (remote control), detect keypad input, IIC
I/O communication, TV tuning control, sound control, and
power control.
The embedded video decoder is used to execute all video
signals processing except for HDTV. The HDTV streams go
through an embedded ADC converter. 3D comb and 3D deinterlacer are included in the Scaler. The Scaler can decode
CC, TXT, and V-chip data to display.
One audio decoder MSP34XXG is used for TV sound
processing, and output goes via the TPA3100D2PHPR D-class
amplifier on the Scaler board.
The iTV board (i-Board) is a buy-in product, so it is a black-box
for Service. When defective, replace the whole unit. It is for iTV
“level two” system usage. The iTV “level two” is the system for
a Hotel centre controller to control the monitor and take the
service for the customer. It is a two-way communication
between Hotel centre controller and customer. Beside that, the
most important point is that all of the monitor display and work
action is controlled by iTV. The iTV board can update SW
version or communicate with the centre controller by RS232
board (RS232 and RJ45 interface).
Smart Box is the interface for a PHILIPS Smart Card (NEXT
card, DVB-T card, etc.). It is an option item for the customer.
This Smart Box is controlled by the iTV board and sends the
signal from the Smart Card to the Scaler for display.
