REPAIRING AND NOT THROWING AWAY

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 -32PFL6615D – 40PFL6615D – 46PFL6615D - VAN GOGH – DA VINCI – MATISSE _Q552.1L - ERROR CODES & DETAILS




ERROR CODES DESCRIPTION

     The error code buffer contains all detected errors since the last time the buffer was erased. The buffer is written from left to right, new errors are logged at the left side, and all other errors shift one position to the right.  When an error occurs, it is added to the list of errors, provided the list is not full. When an error occurs and the error buffer is full, then the new error is not added, and the error buffer stays intact (history is maintained).  To prevent that an occasional error stays in the list forever, the error is removed from the list after more than 50 hrs. of operation.
    When multiple errors occur (errors occurred within a short time span), there is a high probability that there is some relation between them.


New in this chassis is the way errors can be displayed:
If no errors are there, the LED should not blink at all in CSM or SDM. No spacer must be displayed as well.
There is a simple blinking LED procedure for board level repair (home repair) so called LAYER 1 errors next to the existing errors which are LAYER 2 errors.
LAYER 1 errors are one digit errors.
LAYER 2 errors are 2 digit errors.
  • In protection mode.
From consumer mode: LAYER 1.
From SDM mode: LAYER 2.
  • Fatal errors, if I2C bus is blocked and the set reboots, CSM and SAM are not selectable.
From consumer mode: LAYER 1.
From SDM mode: LAYER 2.
  • In CSM mode.
When entering CSM: error LAYER 1 will be displayed by blinking LED. Only the latest error is shown
  • In SDM mode.
When SDM is entered via Remote Control code or the hardware pins, LAYER 2 is displayed via blinking LED.
  • Error display on screen.
In CSM no error codes are displayed on screen.
In SAM the complete error list is shown.
  • Basically there are three kinds of errors:
  1. Errors detected by the Stand-by software which lead to protection. These errors will always lead to protection and an automatic start of the blinking LED LAYER 1 error.
  2. Errors detected by the Stand-by software which not lead to protection. In this case the front LED should blink the involved error.  Note that it can take up several minutes before the TV starts blinking the error (e.g. LAYER 1 error = 2, LAYER 2 error = 15 or 53).
  3. In this case the error will be logged into the error buffer and can be read out via ComPair, via blinking LED method LAYER 1-2 error, or in case picture is visible, via SAM.
HOW TO READ ERROR BUFFER
Use one of the following methods:
On screen via the SAM (only when a picture is visible).
E.g.:
  • 00 00 00 00 00: No errors detected
  • 23 00 00 00 00: Error code 23 is the last and only detected error.
  • 37 23 00 00 00: Error code 23 was first detected and error code 37 is the last detected error.  Note that no protection errors can be logged in the error buffer.
HOW TO CLEAR ERROR BUFFER
Use one of the following methods:
  1. By activation of the “RESET ERROR BUFFER” command in the SAM menu.
  2. If the content of the error buffer has not changed for 50+ hours, it resets automatically.
Error Buffer
In case of non-intermittent faults, clear the error buffer before starting to repair (before clearing the buffer, write down the content, as this history can give significant information). This to ensure that old error codes are no longer present.
If possible, check the entire contents of the error buffer. In some situations, an error code is only the result of another error code and not the actual cause (e.g. a fault in the protection detection circuitry can also lead to a protection).
There are several mechanisms of error detection:
  • Via error bits in the status registers of ICs.
  • Via polling on I/O pins going to the stand-by processor.
  • Via sensing of analog values on the stand-by processor or the PNX85500.
  • Via a “not acknowledge” of an I2C communication.
Take notice that some errors need several minutes before they start blinking or before they will be logged. So in case of problems wait 2 minutes from start-up onwards, and then check if the front LED is blinking or if an error is logged.
