SELF-DIAGNOSTIC FUNCTION OPERATION.

2 : temp

When temperature sensor on the S2 board detects high temperature, or I2C line connector (CN6804: G board, CN160: S2 board) is not seated securely, the TV-micro turns off the lamp.  When the temperature sensor on the HB board detects high temperature, or I2C line connector (CN3008: B board, CN110: HB board) is not seated securely, the TV-micro turns off the lamp.

3: Lamp cover or Lamp position.

The rib at the back of the lamp cover closes the SW on the T1 board.  The lamp closes the SW on the T2 board.  It is monitored by the TV micro (Pin150 of IC3002) and turns off the lamp when it is opened.

4: Fan error

Fan rotation is detected by “FAN-PROT” and the TV micro (Pin 137 of IC3002) turns off the lamp when it is “high”

5: Lamp driver

When the “LAMP-PROT” (Pin 151 IC3002) is high, the lamp is not turned on.  If the “LAMP-HV-DET” (Pin 152 IC3002) is low at the same time, it is classified as no high voltage of the lamp driver.

6: Low B LVP

When no B-10.5V is detected, pin 129 of the TV micro is low and it turns off the main power.

8: Low B OVP

When overvoltage of B-10.5V is detected, pin 126 of the TV micro is low and it turns off the main power.

LAMP: Lamp

When the “LAMP-PROT” (Pin 151 of IC3002) (normally at 0V) is high (5V), the self-diagnosis detects the problem and puts the set into Lamp protect mode and turns the lamp off.

If the “LAMP-HV-DET” (Pin 152 of IC3002) is high, at the same time, it’s classified as no lamp of burned out lamp.

Philips CED229-51-55-98 Car Audio Video System-software update, circuit diagram and wiring diagram

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.

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: KX2B0835000001) indicates the number of the alternative B.O.M. (Bill Of Materials) that has been used for producing the specific AV set. In general, it is possible that the same AV model on the market is produced with e.g. two different types of display, coming from two different suppliers. This will then result in sets which have the same CTN (Commercial Type Number; e.g. MCM394/12) but which have a different B.O.M. number.

Also, it is possible that same model on the market is produced with two production centers, however their parts list is the same.  In such case, no alternative B.O.M. will be created.

By looking at the third digit of the serial number, one can identify which B.O.M. is used for the set he is working with.  If the third digit of the serial number contains the number “1” (example: KX1B033500001), then the set has been manufactured according to B.O.M. number 1. If the third digit is a “2” (example: KX2B0335000001), 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. LM is Arts), 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 2008 week 50). The 6 last digits contain the serial number.

Module Level Repair (MLR) or Component Level Repair (CLR).

If a board is defective, consult your repair person to decide if the board has to be exchanged or if it should be repaired on component level.  If your repair person 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.

PCB locations.

Disassembly procedure.

Software check and upgrade.

1. Copy the file “MCU.BIN” into a USB stick.

2. Power ON the device, and plug the USB stick into USB socket.  After the device read the content in the USB, the LCD will show a upgrade menu, and enter into the upgrading status.

3. The LCD will show a number (changed from 20 to 0), and when arrived the number 0, then appear a processing bar, which mean the device enters upgrading status.

4. in step 3, if want to enter into the upgrading status quickly, press the key OK to confirm, the processing bar will appear immediately.

6. When software upgrade is complete, the device will power off automatically.

Check servo software version.

1. Copy the file “ROM.BIN” into USB stick. (delete the file “MCU.BIN”)

2. Power ON the device, and plug the USB stick into USB socket.  After the device read the content in the USB, the LCD will show a upgrade menu, and enter into the upgrading status.

3. The LCD will show a number (changed from 20 to 0), and when arrived the number 0, then appear a processing bar, which means the device enters upgrading status.

4, press the key OK to confirm, the processing bar will appear immediately.

5. Disconnect the USB stick.

6. When software upgrade complete, the device will change to DISC mode automatically.

When the device is power ON at the first time, in USB or SD or Disc mode, press the key in turn:

Stop > Up > Down > Left > Right

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. SN is Lysomice, RJ is Kobierzyce), 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 2010 week 10 / 2010 week 17). The 6 last digits contain the serial number.



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.

Error Code Error codes are required to indicate failures in the TV set. In principle a unique error code is available for every:

• Activated (SW) protection.

• Failing I2C device.

• General I2C error.

The last five errors, stored in the NVM, are shown in the Service menu’s. This is called the error buffer.

The error code buffer contains all errors detected since the last time the buffer was erased. The buffer is written from left to right. When an error occurs that is not yet in the error code buffer, it is displayed at the left side and all other errors shift one position to the right.

An error will be added to the buffer if this error differs from any error in the buffer. The last found error is displayed on the left.

An error with a designated error code never leads to a deadlock situation. It must always be diagnosable (e.g. error buffer via OSD or blinking LED).

In case a failure identified by an error code automatically results in other error codes (cause and effect), only the error code of the MAIN failure is displayed.

How to Read the Error Buffer

You can read the error buffer in following ways:

• On screen via the SAM/CSM (if you have a picture).

Example:

– ERROR: 000 000 000 000 000: No errors detected

– ERROR: 013 000 000 000 000: Error code 13 is the last and only detected error

– ERROR: 034 013 000 000 000: Error code 13 was detected first and error code 34 is the last detected (newest) error

Via the blinking LED procedure (when you have no picture).

Error codes overview

In this chassis only “layer 2” error codes are available and point to problems on the SSB. They are triggered by LED blinking when CSM is activated. Only the following layer 2 errors are defined:


How to Clear the Error Buffer

The error code buffer is cleared in the following cases:

• By using the CLEAR command in the SAM menu

• By using the CLEAR command in the Factory mode:

• By using the following key sequence on the remote control transmitter: “062599” directly followed by the OK button.

• If the contents of the error buffer have not changed for 50 hours, the error buffer resets automatically.

Note: If you exit SAM by disconnecting the mains from the television set, the error buffer is not reset.

Set Option Code

Press the following key sequence on a standard RC transmitter: “062598” directly followed by MENU and “xxx”, where “xxx” is a 3 digit decimal value of the panel type: see column “Set Option Code” in below tab. After resetting the Display Code, restart the set immediately.
