Safety Instructions, Warnings, and Notes
EN 6 Q529.1E LA2.
2. Safety Instructions, Warnings, and Notes
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 MΩand 12 MΩ.
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
• 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).
• 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.
2.3.2 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 kΩ).
• Resistor values with no multiplier may be indicated with
either an “E” or an “R” (e.g. 220E or 220R indicates 220 Ω).
• All capacitor values are given in micro-farads (μ=× 10-6),
nano-farads (n =× 10-9), or pico-farads (p =× 10-12).
• 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 login, 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.
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

Directions for Use EN 7Q529.1E LA 3.
avoid mixed regimes. If this cannot be avoided, carefully
clear the solder-joint from old tin and re-solder with new tin.
2.3.5 Alternative BOM identification
Be aware: on the European Service website, “Alternative
BOM” is referred to as “Design variant”.
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 center (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.
Figure 2-1 Serial number (example)
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.
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.

4.2 Service 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).
4.2.1 Foam Bars
Figure 4-3 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, the screen can
be monitored.

5.1 Test Points
As most signals are digital, it will be difficult to measure
waveforms with a standard oscilloscope. However, several key
ICs are capable of generating test patterns, which can be
controlled via ComPair. In this way it is possible to determine
which part is defective.
Perform measurements under the following conditions:
• Service Default Mode.
• Video: Colour bar signal.
• Audio: 3 kHz left, 1 kHz right.
5.2 Service Modes
Service Default mode (SDM) and Service Alignment Mode
(SAM) offers several features for the service technician, while
the Customer Service Mode (CSM) is used for communication
between the call centre and the customer.
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.
(see also section “5.4.1 ComPair”).
5.2.1 Service Default Mode (SDM)
Purpose
• To create a pre-defined setting, to get the same
measurement results as given in this manual.
• To override SW protections detected by stand-by
processor and make the TV start up to the step just before
protection (a sort of automatic stepwise start up). See
section “5.3 Stepwise Start-up”.
• To start the blinking LED procedure where only layer 2
errors are displayed. (see also section “5.5 Error Codes”)
Specifications
Table 5-1 SDM default settings
• All picture settings at 50% (brightness, colour, contrast).
• All sound settings at 50%, except volume at 25%.
• All service-unfriendly modes (if present) are disabled, like:
– (Sleep) timer.
– Child/parental lock.
– Picture mute (blue mute or black mute).
– Automatic volume levelling (AVL).
– Skip/blank of non-favourite pre-sets.
How to Activate SDM
For this chassis there are two kinds of SDM: an analog SDM
and a digital SDM. Tuning will happen according table “SDM
Default Settings”.
•Analog SDM: use the standard RC-transmitter and key in
the code “062596”, directly followed by the “MENU” button.
Note: It is possible that, together with the SDM, the main
menu will appear. To switch it “off”, push the “MENU”
button again.
•Digital SDM: use the standard RC-transmitter and key in
the code “062593”, directly followed by the “MENU” button.
Note: It is possible that, together with the SDM, the main
menu will appear. To switch it “off”, push the “MENU”
button again.
•Analog SDM can also be activated by shorting for a
moment the two solder pads (see figure “Service mode
pads”) on the SSB, with the indication “SDM”.
Figure 5-1 Service mode pads
After activating this mode, “SDM” will appear in the upper right
corner of the screen (when a picture is available).
How to Navigate
When the “MENU” button is pressed on the RC transmitter, the
set will toggle between the SDM and the normal user menu
(with the SDM mode still active in the background).
How to Exit SDM
Use one of the following methods:
• Switch the set to STAND-BY via the RC-transmitter.
• Via a standard customer RC-transmitter: key in “00”-
sequence.
5.2.2 Service Alignment Mode (SAM)
Purpose
• To perform (software) alignments.
• To change option settings.
• To easily identify the used software version.
• To view operation hours.
• To display (or clear) the error code buffer.
How to Activate SAM
Via a standard RC transmitter: key in the code “062596”
directly followed by the “INFO” button. After activating SAM
with this method a service warning will appear on the screen,
continue by pressing the red button on the RC.

Service Modes, Error Codes, and Fault Finding EN 15Q529.1E LA 5.
Contents of SAM:
•Hardware Info.
–A. SW Version. Displays the software version of the
main software (example: Q591E-1.2.3.4 =
AAAAB_X.Y.W.Z).
•AAAA= the chassis name.
•B= the region: A= AP, E= EU, L= LatAm, U = US.
For AP sets it is possible that the Europe software
version is used.
•X.Y.W.Z= the software version, where X is the
main version number (different numbers are not
compatible with one another) and Y.W.Z is the sub
version number (a higher number is always
compatible with a lower number).
–B. SBY PROC Version. Displays the software version
of the stand-by processor.
–C. Production Code. Displays the production code of
the TV, this is the serial number as printed on the back
of the TV set. Note that if an NVM is replaced or is
initialized after corruption, this production code has to
be re-written to NVM. ComPair will foresee in a
possibility to do this.
•Operation Hours. Displays the accumulated total of
operation hours (not the stand-by hours). Every time the
TV is switched “on/off”, 0.5 hours is added to this number.
•Errors (followed by maximum 10 errors). The most recent
error is displayed at the upper left (for an error explanation
see section “5.5 Error Codes”).
•Reset Error Buffer. When “cursor right” (or the “OK
button) is pressed and then the “OK” button is pressed, the
error buffer is reset.
•Alignments. This will activate the “ALIGNMENTS” sub-
menu.
•Dealer Options. Extra features for the dealers.
•Options. Extra features for Service. For more info
regarding option codes, see chapter 8 “Alignments”.
Note that if the option code numbers are changed, these
have to be confirmed with pressing the “OK” button before
the options are stored. Otherwise changes will be lost.
•Initialize NVM. The moment the processor recognizes a
corrupted NVM, the “initialize NVM” line will be highlighted.
Now, two things can be done (dependent of the service
instructions at that moment):
– Save the content of the NVM via ComPair for
development analysis, before initializing. This will give
the Service department an extra possibility for
diagnosis (e.g. when Development asks for this).
– Initialize the NVM.
Note: When the NVM is corrupted, or replaced, there is a high
possibility that no picture appears because the display code is
not correct. So, before initializing the NVM via the SAM, a
picture is necessary and therefore the correct display option
has to be entered. Refer to chapter 8 “Alignments” for details.
To adapt this option, it’s advised to use ComPair (the correct
HEX values for the options can be found in chapter 8
“Alignments”) or a method via a standard RC (described
below).
Changing the display option via a standard RC: Key in the
code “062598” directly followed by the “MENU” button and
“XXX” (where XXX is the 3 digit decimal display code as
mentioned in table “Option code overview” in chapter 8
“Alignments”). Make sure to key in all three digits, also the
leading zero’s. If the above action is successful, the front LED
will go out as an indication that the RC sequence was correct.
After the display option is changed in the NVM, the TV will go
to the Stand-by mode. If the NVM was corrupted or empty
before this action, it will be initialized first (loaded with default
values). This initializing can take up to 20 seconds.
Figure 5-2 Location of Display Option Code sticker
•Store - go right. All options and alignments are stored
when pressing “cursor right” (or the “OK” button) and then
the “OK”-button.
•SW Maintenance.
–SW Events. Not useful for Service purposes. In case
of specific software problems, the development
department can ask for this info.
–HW Events. Not useful for Service purposes. In case
of specific software problems, the development
department can ask for this info.
•Test settings. For development purposes only.
•Upload to USB. To upload several settings from the TV to
an USB stick, which is connected to the SSB. The items are
“Channel list”, “Personal settings”, “Option codes”,
“Display-related alignments” and “History list”. First a
directory “repair\” has to be created in the root of the USB
stick. To upload the settings select each item separately,
press “cursor right” (or the “OK button), confirm with “OK”
and wait until “Done” appears. In case the download to the
USB stick was not successful “Failure” will appear. In this
case, check if the USB stick is connected properly and if
the directory “repair” is present in the root of the USB stick.
Now the settings are stored onto the USB stick and can be
used to download onto another TV or other SSB.
Uploading is of course only possible if the software is
running and if a picture is available. This method is created
to be able to save the customer’s TV settings and to store
them into another SSB.
•Download to USB. To download several settings from the
USB stick to the TV. Same way of working as with
uploading. To make sure that the download of the channel
list from USB to the TV is executed properly, it is necessary
to restart the TV and tune to a valid preset if necessary.
Note: The “History list item” can not be downloaded from
USB to the TV. This is a “read-only” item. In case of
specific problems, the development department can ask
for this info.
•Development file versions. Not useful for Service
purposes, this information is only used by the development
department.
How to Navigate
• In SAM, the menu items can be selected with the
“CURSOR UP/DOWN” key (or the scroll wheel) on the RC-
transmitter. The selected item will be highlighted. When not
all menu items fit on the screen, move the “CURSOR UP/
DOWN” key to display the next/previous menu items.
• With the “CURSOR LEFT/RIGHT” keys (or the scroll
wheel), it is possible to:
– (De) activate the selected menu item.
– (De) activate the selected sub menu.
• With the “OK” key, it is possible to activate the selected
action.
How to Exit SAM
Use one of the following methods:
• Press the “MENU” button on the RC-transmitter.

• Switch the set to STAND-BY via the RC-transmitter.
5.2.3 Customer Service Mode (CSM)
Purpose
When a customer is having problems with his TV-set, he can
call his dealer or the Customer Helpdesk. The service
technician can then ask the customer to activate the CSM, in
order to identify the status of the set. Now, the service
technician can judge the severity of the complaint. In many
cases, he can advise the customer how to solve the problem,
or he can decide if it is necessary to visit the customer.
The CSM is a read only mode; therefore, modifications in this
mode are not possible.
When in this chassis CSM is activated, a testpattern will be
displayed during 5 seconds (1 second Blue, 1 second Green
and 1 second Red, then again 1 second Blue and 1 second
Green). This test pattern is generated by the PNX5100. So if
this test pattern is shown, it could be determined that the back
end video chain (PNX5100, LVDS, and display) of the SSB is
working.
To determine if the MPEG4-circuit is working (in case of an
MPEG4-set), push the “MUTE” button during CSM to display
another test pattern. This is a forced input selection to make
sure the test pattern is visible. If this test pattern is not shown,
it is possible that the settings are not correct (for instance in
SAM the MPEG4-option is “NOT PRESENT”). The display of
this test pattern is a toggle function, pressing the “MUTE” key
again removes this test pattern.
When CSM is activated and there is a USB stick connected to
the TV, the software will dump the complete CSM content to the
USB stick. The file (Csm.txt) will be saved in the root of the USB
stick. This info can be handy if no information is displayed.
Also when CSM is activated, the layer 1 error is displayed via
blinking LED. Only the latest error is displayed. (see also
section “5.5 Error Codes”).
How to Activate CSM
Key in the code “123654” via the standard RC transmitter.
Note: Activation of the CSM is only possible if there is no (user)
menu on the screen!
How to Navigate
By means of the “CURSOR-DOWN/UP” knob (or the scroll
wheel) on the RC-transmitter, can be navigated through the
menus.
Contents of CSM
The contents are reduced to 3 pages: General, Software
versions and Quality items. The group names itself are not
shown anywhere in the CSM menu.
General
•Set Type. This information is very helpful for a helpdesk/
workshop as reference for further diagnosis. In this way, it
is not necessary for the customer to look at the rear of the
TV-set. Note that if an NVM is replaced or is initialized after
corruption, this set type has to be re-written to NVM.
ComPair will foresee in a possibility to do this.
•Production Code. Displays the production code (the serial
number) of the TV. Note that if an NVM is replaced or is
initialized after corruption, this production code has to be
re-written to NVM. ComPair will foresee a in possibility to
do this.
•Installed date. Indicates the date of the first installation of
the TV. This date is acquired via time extraction.
•Options 1. Gives the option codes of option group 1 as set
in SAM (Service Alignment Mode).
•Options 2. Gives the option codes of option group 2 as set
in SAM (Service Alignment Mode).
•12NC SSB. Gives an identification of the SSB as stored in
NVM. Note that if an NVM is replaced or is initialized after
corruption, this identification number has to be re-written to
NVM. ComPair will foresee in a possibility to do this. This
identification number is the 12nc number of the SSB.
•12NC display. Shows the 12NC of the display
•12NC supply. Shows the 12NC of the supply.
•12NC “bolt-on”. Shows the 12NC of the “BOLT-ON”-
module.
Software versions
•Current main SW. Displays the built-in main software
version. In case of field problems related to software,
software can be upgraded. As this software is consumer
upgradeable, it will also be published on the Internet.
Example: Q591E_1.2.3.4
•Standby SW. Displays the built-in stand-by processor
software version. Upgrading this software will be possible
via ComPair or via USB (see chapter Software upgrade).
Example: STDBY_3.0.1.2.
•MOP ambient light SW. Displays the MOP ambient light
EPLD SW.
•MPEG4 software. Displays the MPEG4 software (optional
for sets with MPEG4).
•PNX5100 boot NVM. Displays the SW-version that is used
in the PNX5100 boot NVM.
Quality items
•Signal quality. Poor / average /good
•Child lock. Not active / active. This is a combined item for
locks. If any lock (Preset lock, child lock, lock after or
parental lock) is active, the item shall show “active”.
•Table channel changed. This item is for development
purpose, it will be defined later.
•Key missing. This is a combined item for keys. The keys
have a separate bit and the sum is displayed in decimal
value.
– HDMI key valid = 001
– MAC key valid = 010
Important remark here : due to a software bug, the
MAC key is missing and not valid when “2” is displayed
in CSM.So, if for instance the HDMI and MAC keys are
both valid, the decimal value in CSM “1” is displayed
and not “3”.
– BDS key valid = 100
If 3 keys are valid the value: “5” is displayed(should be
“7” but due to the software bug).
•CI slot present. If the common interface module is
detected the result will be “YES”, else “NO”.
•HDMI input format. The detected input format of the
HDMI.
•HDMI audio input stream. The HDMI audio input stream
is displayed: present / not present.
•HDMI video input stream. The HDMI video input stream
is displayed: present / not present.
How to Exit CSM
Press “MENU” on the RC-transmitter.

Service Modes, Error Codes, and Fault Finding EN 17Q529.1E LA 5.
5.3 Stepwise Start-up
When the TV is in a protection state due to an error detected by
stand-by software (error blinking is displayed) and SDM is
activated via shortcutting the pins on the SSB, the TV starts up
until it reaches the situation just before protection. So, this is a
kind of automatic stepwise start-up. In combination with the
start-up diagrams below, you can see which supplies are
present at a certain moment. Important to know is, that if e.g.
the 3V3 detection fails and thus error layer 2 = 18 is blinking
while the TV is restarted via SDM, the Stand-by Processor will
enable the 3V3, but the TV set will not go to protection now.
The TV will stay in this situation until it is reset (Mains/AC
Power supply interrupted). Caution: in case the start up in this
mode with a faulty FET 7U08 is done, you can destroy all IC’s
supplied by the +3V3, due to overvoltage (12V on 3V3-line). It
is recommended to measure first the FET 7U08 or others
FET’s on shortcircuit before activating SDM via the service
pads.
The abbreviations “SP” and “MP” in the figures stand for:
• SP: protection or error detected by the Stand-by
Processor.
• MP: protection or error detected by the MIPS Main
Processor.

Delay of 50ms needed because of the latency of the detect-1 circuit.
This delay is also needed for the PNX5100. The reset of the
PNX5100 should only be released 10ms after powering the IC.
Detect2 should be polled on the standard 40ms
interval and startup should be continued when
detect2 becomes high.

Added to make the system more robust to
power dips during startup. At this point the
regular supply fault detection algorithm which
normally detects power dips is not up and
running yet.

In case of a LED backlight display, a LED DIM panel is
present which is fed by the Vdisplay. To power the LED DIM
Panel, the Vdisplay switch driven by the PNX 5100 must be
closed. The display startup sequence is taken care of by the
LED DIM panel.

Wait until previous on-state is left more than 2
seconds ago. (to prevent LCD display problems)
The assumption here is that a fast toggle (<2s)
can only happen during ON -> SEMI -> ON. In
these states, the AVC is still active and can
provide the 2s delay. If the transition ON-> SEMI-
>STBY -> SEMI -> ON can be made in less than 2s,
the semi -> stby transition has to be delayed
until the requirement is met.
Switch Audio -Reset low and wait 5ms
Constraints taken into account:
- Display may only be started when valid LVDS output clock can be delivered by the AVC .
- Between 5 and 50 ms after power is supplied, display should receive valid lvds clock .
- minimum wait time to switch on the lamp after power up is 200ms.
unblank the video.
Wait until valid and stable audio and video , corresponding to
the requested output is delivered by the AVC.
The higher level requirement is that audio and
video should be demuted without transient
effects and that the audio should be demuted
maximum 1s before or at the same time as the
unblanking of the video.
Release audio mute and wait 100ms before any other audio
handling is done (e.g. volume change)
CPipe already generates a valid output
clock in the semi -standby state : display
