Precautions, Notes, and Abbreviation List EN 5RAM1.0A LA 3.
2010-Mar-12
3. Precautions, Notes, and Abbreviation ListIndex of this chapter:3.1 Safety Instructions3.2 Warnings3.3 Notes3.4 Abbreviation List
3.1 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 ,
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. Of de set ontploft!
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 M and 12 M.
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.
3.2 Warnings
All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD ). 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.
3.3 Notes
3.3.1 General
Measure the voltages and waveforms with regard to the chassis (= tuner) ground (), or hot ground (), depending on the tested area of circuitry. The voltages and waveforms shown in the diagrams are indicative. Measure them in the Service Default Mode 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 () and without () aerial signal. Measure the voltages in the power supply section both in normal operation () and in stand-by (). These values are indicated by means of the appropriate symbols.
3.3.2 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 k).
Resistor values with no multiplier may be indicated with either an E or an R (e.g. 220E or 220R indicates 220 ).
All capacitor values are given in micro-farads ( = 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 on the Philips Spare Parts Web Portal.
3.3.3 Spare Parts
For the latest spare part overview, consult your Philips Spare Part web portal.
3.3.4 BGA (Ball Grid Array) ICs
IntroductionFor more information on how to handle BGA devices, visit this URL: http://www.atyourservice-magazine.com. Select Magazine, then go to Repair downloads. Here you will find Information on how to deal with BGA-ICs.
BGA Temperature ProfilesFor BGA-ICs, you must use the correct temperature-profile. Where applicable and available, this profile is added to the IC Data Sheet information section in this manual.
3.3.5 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. 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 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 360C - 380C is reached and stabilized 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 avoid mixed regimes. If this cannot be avoided, carefully clear the solder-joint from old tin and re-solder with new tin.

3.3.6 Alternative BOM identification
It should be noted that 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 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.
Figure 3-1 Serial number (example)
3.3.7 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!
3.3.8 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 a TV set, the set should be put face down on a soft flat surface, foam buffers or other specific workshop tools. Ensure that a stable situation is created to perform measurements and alignments. When using foam bars take care that these always support the cabinet and never only the display. Caution: Failure to follow these guidelines can seriously damage the display! Ensure that ESD safe measures are taken.

5.1 Service Modes
The Customer Service Mode (CSM) is used for communication between the call centre and the customer, while the Service Alignment Mode (SAM) offers several features for the service technician. The Standard Default Mode (SDM) creates a pre-defined setting.
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.
5.1.1 Service Default Mode (SDM)
Purpose To create a pre-defined setting, to get the same
measurement results as given in this manual To start the blinking LED procedure where only Layer 2
errors are displayed (see also Table 5-1).
How to ActivateUse the standard RC transmitter and key in the code 062596, directly followed by the MENU button.
How to ExitSwitch the set to STANDBY.
5.1.2 Customer Service Mode (CSM)
PurposeThe 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 Activate CSMKey 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!

5.2 Service Tools
5.2.1 ComPair
IntroductionComPair (Computer Aided Repair) is a Service tool for Philips Consumer Electronics products. and offers the following:1. ComPair helps 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. No knowledge on I2C or UART commands is necessary, 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 upgrade possibilities.
SpecificationsComPair consists of a Windows based fault finding program and an interface box between PC and the (defective) product. The 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).The ComPair fault finding program is able to determine the problem of the defective television, by a combination of automatic diagnostics and an interactive question/answer procedure.
How to ConnectThis is described in the chassis fault finding database in ComPair.
Figure 5-5 ComPair II interface connection
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 damaged!
How to OrderComPair II order codes: ComPair II interface: 3122 785 91020. Programming software can be downloaded from the Philips
Service portal. ComPair UART interface cable for RAM1.1x xx.

White point alignment LCD screens: Use a 100% white screen as input signal and set the
following values: Colour temperature: Normal. All White point values to: 127. Red BL offset value to 240 for HDMI source. Green BL offset value to 240 for HDMI source. Red BL offset value to 0 for VGA source. Green BL offset value 0 for VGA source.
In case you have a colour analyser: Measure with a calibrated contactless (max. 25 mm) colour
analyser 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 127) by means of decreasing the value of one or two other white points to the correct x, y coordinates (see Table 6-1). Tolerance: dx: 0.004, dy: 0.004.
Repeat this step for the other colour temperatures that need to be aligned.
When finished press OK on the RC and then press STORE (in the SAM root menu) to store the aligned values to the NVM.
Restore the initial picture settings after the alignments.
Table 6-1 White D alignment values
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. Select a COLOUR TEMPERATURE (e.g. COOL,
NORMAL, or WARM). Set the White point RED, GREEN and BLUE default
values according to the values in Table 6-2. When finished press OK on the RC, then press STORE (in
the SAM root menu) to store the aligned values to the NVM. Restore the initial picture settings after the alignments.

6.5 Reset of Repaired SSB
A very important issue towards a repaired SSB from a service repair shop implies the reset of the NVM on the SSB.A repaired SSB in service should get the service Set type 00PF0000000000 and Production code 00000000000000.Also the virgin bit is to be set. To set all this, you can use the ComPair tool.

7.3 MT8222 Video/Audio processor
Refer to figure Figure 7-4 for the power architecture of this platform.
Figure 7-4 MT8222 Video/Audio system application
7.3.1 Signal paths
RGBAnalogue RGB signals are transferred by the MT8222 to a digital signal by the internal A/D converter. The MT8222 generates an LVDS signal to the TL2428 on-chip TCON which drives the LCD display.
HDMIHDMI signals are further processed digitally by the MT8222. The MT8222 generates an LVDS signal to the TL2428 on-chip TCON which drives the LCD display.
Component InputComponent signals are processed by the MT8222. The MT8222 generates an LVDS signal to the TL2428 on-chip TCON which drives the LCD display.Audio is separately processed by the MT8222 and further processed by the CS4344 and then the audio amplifier.
RF InputRF input signals are demodulated by the TDA9885 IF demodulator and further processed by the MT8222. The signal is then split into an video and an audio part.
The video signal is further processed by the MT8222 which generates an LVDS signal to the TL2428 on-chip TCON which drives the LCD display.The audio signal is further processed by the MT8222 and split into two parts. One part drives the Stereo Line Driver AUDIO OUT chain, the other part drives the CS4344 and the audio amplifier.
