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.
2.3.2
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
(= x10-6), nano-farads (n= x10-9), or pico-farads (p= x10-12).
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
Rework 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.
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.
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. 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.
2.32.3.1
NotesGeneral 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
Safety Instructions, Warnings, and NotesDevice 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 Repair
downloads. 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).

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 90C) 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 mix of two alloys). Caution: For BGA-ICs, you must use the
correct temperatureprofile, 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.
2.3.5 Alternative BOM identification In September 2003, Philips CE
introduced a change in the way the serial number (or production
number, see Figure 2-1) is composed. From this date on, the third
digit in the serial number (example: AG2B0335000001) indicates the
number of the alternative BOM (Bill of Materials used for producing
the specific model of TV set). 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 O.E.M.s. By looking at the
third digit of the serial number, the service technician can see if
there is more than one type of B.O.M. used in the production of the
TV set he is working with. He can then consult the At Your Service
Web site, where he can type in the Commercial Type Version Number
of the TV set (e.g. 28PW9515/12), after which a screen will appear
that gives information about the number of alternative B.O.M.s
used. If the third digit of the serial number contains the number 1
(example: AG1B033500001), then there is only one B.O.M. version of
the TV set on the market. If the third digit is a 2 (example:
AG2B0335000001), then there are two different B.O.M.s. Information
about 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. 2.3.6 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.

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 400C. 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 360C - 380C is reached and stabilised at the
solder joint. Heating time of the solder-joint should not exceed ~
4 sec. Avoid temperatures above 400C, 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

chapter: 5.1 Test Points 5.2 Service Modes 5.3 Stepwise Start-up
5.5 Error Codes 5.6 The Blinking LED Procedure 5.7 Protections 5.8
Fault Finding and Repair Tips 5.9 Software Upgrading All
service-unfriendly modes (if present) are disabled, like: (Sleep)
timer. Child/parental lock. Picture mute (blue mute or black mute).

menu time-out.
5.1
Test PointsThe chassis is equipped with test points (Fxxx)
printed on the circuit board assemblies. As most signals are
digital, it will be difficult to measure waveforms with a standard
oscilloscope. 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 ModesService 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. Minimum requirements for ComPair: a Pentium
processor, a Windows OS, and a CD-ROM drive (see also paragraph
"ComPair").
How to Activate SDM For DVBT TVs there are two kinds of SDM : an
analogue SDM and a digital SDM. Tuning will happen according table
SDM Default Settings. Analogue 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. Depending on the
software version it is possible that the tuning will not work
correctly. Note: It is possible that, together with the SDM, the
main menu will appear. To switch it "off", push the MENU button
again. Analogue SDM can also be activated by shorting for a moment
the two solder pads [1] on the SSB, with the indication SDM. They
are located outside the shielding. Activation can be performed in
all modes, except when the set has a problem with the Stand-by
Processor. See figure Service mode pads.
SDM

5.2.1
Service Default Mode (SDM)
2 1Purpose 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 paragraph Stepwise Start Up. To override SW
protections detected by Viper. Depending on the SW version it is
possible that this mechanism does not work correctly. See also
paragraph Error codes. To start the blinking LED procedure (not
valid in protection mode). Specifications Table 5-1 SDM default

G_15990_142.eps 110506
Figure 5-1 Service mode pads After activating this mode, SDM
will appear in the upper right corner of the screen (if you have
picture). How to Navigate When you press the MENU button 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.

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, you can continue by pressing the red
button on the RC. Contents of SAM: Hardware Info. A. SW Version.
Displays the software version of the VIPER software (main software)
(example: JA30E1.2.3.4_12345 = AAAAB_X.Y.W.Z_NNNNN). AAAA= the
software 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). NNNNN= last five digits of 12nc code of the
software. 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 maximal 10 errors). The most
recent error is displayed at the upper left (for an error
explanation see paragraph Error Codes). Defective Module. Here the
module that generates the error is displayed. If there are multiple
errors in the buffer, which are not all generated by a single
module, there is probably another defect. It will then display the
message UNKNOWN here. Not all errors will display a defective
module name. Reset Error Buffer. When you press cursor right and
then the OK button, the error buffer is reset. Alignments. This
will activate the ALIGNMENTS submenu. Dealer Options. Extra
features for the dealers. Options. Extra features for Service. For
more info regarding option codes, see chapter 8. Note that if you
change the option code numbers, you have to confirm your changes
with the OK button before you store the options. Otherwise you will
lose your changes. Initialise NVM. When an NVM was corrupted (or
replaced) in the former EMG based chassis, the microprocessor
replaces the content with default data (to assure that the set can
operate). However, all preferences and alignment values are gone
now, and option numbers are not correct. Therefore, this was a very
drastic way. In this chassis, the procedure is implemented in
another way: The moment the processor recognizes a corrupted NVM,
the initialize NVM line will be highlighted. Now, you can do two
things (depending 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 (same as in the
past, however now it happens conscious).
Note: When you have a corrupted NVM, or you have replaced the
NVM, there is a high possibility that you will not have picture any
more because your display option is not correct. So, before you can
initialize your NVM via the SAM, you need to have picture and
therefore you need the correct display option. To adapt this
option, you can use ComPair (the correct HEX values for the options
can be found in the table below) 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 option code as mentioned
in the first column of the next table). Make sure to key in all
three digits, also the leading zeros. 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 initialised first (loaded
with default values). This initialising can take up to 20 seconds.

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 colour bar test
pattern will be visible for 5 seconds. This test pattern is
generated by the Pacific3. So if you see this test pattern you can
determine that the back end video chain (Pacific3, LVDS and
display) is working. Also new in this chassis: when you activate
CSM 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 your USB stick. This info can be handy
if you dont have picture. 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 on the RCtransmitter,
you can navigate through the menus. Contents of CSM 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 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 possibility to do this.
Code 1. Gives the latest five errors of the error buffer. As soon
as the built-in diagnose software has detected an error the buffer
is adapted. The last occurred error is displayed on the leftmost
position. Each error code is displayed as a 2-digit number. When
less than 10 errors occur, the rest of the buffer is empty (00).
See also paragraph Error Codes for a description. Code 2. Gives the
first five errors of the error buffer. See also paragraph Error
Codes for a description. 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 a possibility to do this. This
identification number consists of 14 characters and is built up as
follows: - 8 last characters of the 12NC of the SSB itself. - the
serial number of the SSB, which consists of 6 digits. Both can be
found on a sticker on the PWB of the SSB itself (not on the sticker
on the outside of the shielding!). The format of the identification
number is then as follows: (total 14 characters). Digital Natural
Motion. Gives the last status of the Digital Natural Motion
setting, as set by the customer. Possible

root of the USB stick.To upload the settings you have to select
each item separately, press cursor right, confirm with OK and wait
until Done appears. Now the settings are stored onto your 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 you
have picture. This method is created to be able to save the
customers TV settings and to store them into another SSB. Download
from USB. Here you are able 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

Mode of Converter Boards for Ambi Light Purpose To switch on the
lamps manually in case I2C-bus triggering fails. The Service Mode
can be activated by disconnecting connectors 1M59 and 1M49 and then
by shorting for a moment the two solder pads [1] on the Ambi Light
Inverter Panel. See figure Service Mode pads.

Service Modes, Error Codes, and Fault FindingRepair Tips In case
only one or no lamp unit at all works, probably the +12Vb (12 - 13
V) is not available or the fuse is broken. Check for broken MOSFETS
or check if they are switched off properly by the transistors
connected to the PWM outputs of the microprocessor.1
In case the Ambi Light switches off after two seconds, serial
arcing or parallel arcing protection is active. Serial arcing
protection can be excluded by disconnecting the opto-coupler; check
for bad solder joints on transformer or lamp units. Parallel arcing
protection can be disabled by grounding pin 8 of the
microprocessor. Usually the switching frequency (normally 63 kHz)
will then be too high. Possible causes are one MOSFET of the
converter has no gate drive or is broken, or there is a
short-circuit of the output of the transformer.G_15950_049.eps

Stepwise Start-upThe stepwise start-up method, as known from
FTL/FTP sets (EMG based sets) is not valid any more. There are two
possible situation: one for protections detected by standby
software and one for protections detected by main software. When
the TV is in a protection state due to an error detected by standby
software (and thus blinking an error) 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 here is, that if e.g. the 3V3 detection
fails (and thus error 11 is blinking) and the TV is restarted via
SDM, the Stand-by Processor will enable the 3V3, but will not go to
protection now. The TV will stay in this situation until it is
reset (Mains/AC Power supply interrupted). When the TV is in
protection state due to an error detected by main software (Viper
protection) and SDM is activated via shortcutting the pins on the
SSB, the TV starts up and ignores the error. Due to architectural
reasons it is possible that the TV will end up in an undefined
state (e.g. when the fast I2C bus is blocked). In this case
diagnose has to be done via ComPair. 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 VIPER
Main Processor. In the next transition diagrams for POD should be
read Common Interface (CI). For analogue sets, any reference to POD
should be neglected.
Figure 5-2 Service Mode pads AmbiLight panel In this chassis,
both single and double fitted boards can be used. The double fitted
boards are used in sets with 3 or 4 sided Ambi Light units whereas
the single fitted boards are used in sets with 2 sided Ambi Light
units. A double fitted board can drive 2 lamp units (6 lamps) and a
single fitted board can drive 1 lamp unit (3 lamps). The double
fitted boards are supplied by +12Va and +12Vb. The microprocessor
is supplied by +12Va. Therefore, if only +12Va is available, lamp

Figure 5-3 Building blocks of Converter Board The microprocessor
performs the following tasks: Dimming of Ambi Light by means of
PWM. Translation of I2C-bus commands to PWM. Switches the Ambi
Light board to protection if needed (in case of protection only the
lamps switch off, no set protection is triggered). There are two
ways of protection: parallel arcing protection and serial arcing
protection. Parallel arcing protection is performed by sensing the
switching frequency. In case of short circuit of the transformer
output, this frequency > 100 kHz and the board goes into
protection. Serial arcing protection is performed by detection of
arc in ground wire of the lamp units. In this case, the protection
pulse is transmitted via an opto-coupler. Protection can be
disabled by short-circuiting diode 6112 or capacitor 2173 or by
connecting pin 8 of the microprocessor to ground.

Service ToolsComPair 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 I2C
level) and is therefore capable of accurately indicating problem
areas. You do not have to know anything about I2C 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 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. 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 fault finding 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
I2C/UART level. ComPair can access the I2C/UART bus of the
television. ComPair can send and receive I2C/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 I2C/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 fault
finding 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 fault finding 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 fault finding 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!TO UART SERVICE CONNECTOR
