Safety Instructions, Warnings, and Notes
2.Safety Instructions, Warnings, and Notes
EN 5QCS1.0S LA2.
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.
2.2Warnings
•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.
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
•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 log-in, select “Magazine”,
then go to “Repair downloads”. Here you will find Information
on how to deal with BGA-ICs.
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.

), or pico-farads (p = × 10
-12
-6
),
).
•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.
•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
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).
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.
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.

EN 6QCS1.0S LA3.
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.

4.1Cable Dressing
Notes:
•Figures below can deviate slightly from the actual situation,
due to the different set executions.
•Follow the disassembly instructions in the described order.
4.2Service Positions
When moving or laying down an LCD set, at least two people
must work together. Avoid any impact towards the PDP set.
For easy servicing of this set, there are a few possibilities
created:
•Foam bars (created for Service).
•Separately available stands.
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
Index of this chapter:
5.1 Compatibility Mode
5.2 Service Mode
5.1Compatibility Mode
This chassis does not contain specific test points, since all
defect boards should be replaced.
Perform measurements under the following conditions:
•Environmental: t
•Service signal: 100% Full White signal
This monitor saves all previously made settings, unless
separately made user settings override this. All timings must be
properly phased, sized and centred. The aspect ratio is
depending on the input signal scaled and centred. At full screen
the input timing is set to completely fill the screen, regards less
of scaling artifacts.
AV over scan: 5~9%
HDMI over scan: No over scan for PC input, 5~9% for video
source.
PC: No over scan
5.1.2Display Processor performance
The display processor performance (excluding scaling
artifacts) has to be judged according to the following
definitions:
•Compatibility mode: correctly recognizes the proper
resolution and applies the correct display scaling to the
image. (i.e. a 1280 × 720 signal is properly recognized).
•Properly sized/centred: The entire image (use display mate
“side tics” pattern) perfectly fits the screen. Even one pixel
off in horizontal or vertical direction, makes this test fail.
•Properly phased: The display processor automatically
computes the correct A/D response so that a Win98
shutdown or all display mate moire patterns are correctly
displayed. Most critical on the panels native mode, no
unstableness of the image may be observed.
•HD compatibility: All HD timings have to work through
YPbPr, HDMI, and RGB.
108016 : 9NoNoYesNoYes
5.2Service Mode
5.2.1Factory Mode
There are two ways to enter the factory mode:
1. On the set:
•Push the y button and turn on the AC power.
2. With the remote control:
•Turn on the set and provide a signal source on an input
(this to prevent to enter the power save mode). On the
remote control press “-”, ”-”, “+”, “+”, “-”, “+”, “-”, “+”,
“SET”, “MENU”.
•Please note that this set does not respond on the

9.11 EtronTech EM636165TS-5G SDRAM
The EM636165 SDRAM is a high-speed CMOS synchronous
DRAM containing 16 Mbits. It is internally configured as a dual
512K word × 16 DRAM with a synchronous interface (all signals
are registered on the positive edge of the clock signal, CLK).
Each of the 512K × 16 bit banks is organized as 2048 rows by
256 columns by 16 bits. Read and write accesses to the
SDRAM are burst oriented; accesses start at a selected
location and continue for a programmed number of locations in
a programmed sequence. Accesses begin with the registration
of a BankActivate command which is then followed by a Read
or Write command. The EM636165 provides for programmable
Read or Write burst lengths of 1, 2, 4, 8, or full page, with a
burst termination option. An auto precharge function may be
enabled to provide a self-timed row precharge that is initiated
at the end of the burst sequence. The refresh functions, either
Auto or Self Refresh are easy to use. By having a
programmable mode register, the system can choose the most
suitable modes to maximize its performance. These devices
are well suited for applications requiring high memory
bandwidth and particularly well suited to high performance PC
applications.

including composite and vertical sync, burst/back porch timing,
and odd/even field information from standard negative going
sync NTSC, PAL*, and SECAM video signals with amplitude
from 0.5 V to 2 V
providing sync separation for non-standard, faster horizontal
rate video signals. The vertical output is produced on the rising
edge of the first serration in the vertical sync period. A default
vertical output is produced after a time delay if the rising edge
mentioned above does not occur within the externally set delay
period, such as might be the case for a non-standard video
signal.
