In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

PHILIPS 42PFL4506 - BLINKING LED PROCEDURE - ERROR CODES - RESET OF REPAIRED SSB [SMALL SIGNAL BOARD]

PHILIPS 42PFL4506 - BLINKING LED PROCEDURE - ERROR CODES - RESET OF REPAIRED SSB [Small Signal Board]


ERROR CODES
  • Error 000:No problem.
  • Error 011:I2C bus error. When this error occurs, the TV will not start up due to the blocked bus.
  • Error 012:Tuner error. There is no I2C communication towards the tuner after start-up.
  • Error 013:Panel VCC error. This voltage is made in the power supply and results in protection in case of absence.
TO CLEAR THE ERROR BUFFER
  • By using the CLEAR command in the SAM menu.
  • 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.
BLINKING LED
The software is capable of identifying different kinds of errors. Because it is possible that more than one error can occur over time, an error buffer is available, which is capable of storing the last five errors that occurred. This is useful if the OSD is not working properly.  Errors can also be displayed by the blinking LED procedure.  The method is to repeatedly let the front LED pulse with as many pulses as the error code number, followed by a period of 1.5 seconds in which the LED is“off”. Then this sequence is repeated.

Example (1):
Error code 4 will result in four times the sequence LED “on” for 0.25 seconds / LED “off” for 0.25 seconds. After this sequence, the LED will be “off” for 1.5 seconds. Any RC command terminates the sequence. Error code LED blinking is in red color.
Example (2):
The content of the error buffer is “12 9 6 0 0” After entering SDM, the following occurs.
  • 1 long blink of 5 seconds to start the sequence.
  • 12 short blinks followed by a pause of 1.5 seconds.
  • 9 short blinks followed by a pause of 1.5 seconds.
  • 6 short blinks followed by a pause of 1.5 seconds.
  • 1 long blink of 1.5 seconds to finish the sequence.
  • The sequence starts again with 12 short blinks.
RESET OF REPAIRED SSB
  • A very important issue towards a repaired SSB from a Service repair shop (SSB repair on component level) 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 has to be set. To set all this, you can use the ComPair tool or use the “NVM editor” and “Service Data” items in SAM (do not forget to “store”).
  • After a repaired SSB has been mounted in the set (set repair on board level), the type number (CTN) and production code of the TV has to be set according to the type plate of the set. For this, you can use the NVM editor in SAM. Loading of the CTN and production code can also be done via ComPair (Model number programming).
  • In case of a display replacement, reset the “Operation hours display” to “0”, or to the operation hours of the replacement display.
