PHILIPS - LC4.1E CHASSIS - LCD TVs - ERROR CODES - LED BLINKING CODES & DETAILS -
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.
HOW TO READ ERROR CODES
On screen via the SAM (if you have a picture).
Examples:
ERROR: 0 0 0 0 0 : No errors detected
ERROR: 6 0 0 0 0 : Error code 6 is the last and only detected error.
ERROR: 9 6 0 0 0 : Error code 6 was detected first and error
code 9 is the last detected (newest) error
Via the blinking LED procedure (when you have no picture).
Via ComPair.
TO CLEAR ERROR BUFFER
By using the CLEAR command in the SAM menu: [to know more about SAM menu, check the previous post here]
- To enter SAM, press the following key sequence on the remote control transmitter: “062596” directly followed by the OSD/STATUS button (do not allow the display to time out between entries while keying the sequence).
- Make sure the menu item CLEAR is highlighted. Use the MENU UP/DOWN buttons, if necessary.
- Press the MENU RIGHT button to clear the error buffer. The text on the right side of the “CLEAR” line will change from “CLEAR?” to “CLEARED”
- If the contents of the error buffer have not changed for 50 hours, the error buffer resets automatically.
ERROR CODES
In case of non-intermittent faults, write down the errors
present in the error buffer and clear the error buffer before you begin the
repair. This ensures 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 and not the actual cause of the problem (for example, a fault in the
protection detection circuitry can also lead to a protection).

LED BLINKING PROCEDURE
When the SDM is entered, the front LED will blink the
contents of the error-buffer:
- The Led blinks with as many pulses as the error code number, followed by a time period of 1.5 seconds, in which the Led is off.
- Then this sequence starts is repeated. Any RC5 command terminates this sequence.
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 at 12 short blinks.
