Safety Instructions, Warnings, and Notes

2. Safety Instructions, Warnings, and Notes

EN 5QCS1.0S LA 2.

Index of this chapter:

2.1 Safety Instructions

2.2 Warnings

2.3 Notes

2.1 Safety 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.

2.2 Warnings

• 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.

2.3.2 Schematic 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.

2.3.3 BGA (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.

),

).

• 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.

2.3 Notes

2.3.1 General

• 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).

2.3.4 Lead-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 6 QCS1.0S LA3.

2.3.5 Alternative 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.

2.3.6 Board 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!

2.3.7 Practical Service Precautions

• It makes sense to avoid exposure to electrical shock.

• Always respect voltages. While some may not be

Figure 2-1 Serial number (example)

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.

4.1 Cable 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.

4.2 Service 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.

4.2.1 Foam 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.

• While re-assembling, make sure that all cables are placed
and connected in their original position. See figure “Cable
dressing”.

• Pay special attention not to damage the EMC foams at the
SSB shields. Make sure, that EMC foams are put correctly
on their places.

5.1 Compatibility 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.

5.1.2 Display 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.

5.2 Service Mode

5.2.1 Factory 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
standard Philips remote controllers, but only responds
to the with the set supplied remote control.
