The Blinking Led Procedure - Philips 7629 Service Manual

The Blinking LED Procedure

Using this procedure, you can make the contents of the error buffer visible via the front
LED. This is especially useful when there is no picture.
When the SDAM is entered, the LED will blink the contents of the error-buffer:
1-12 short blinks (indicates error number 1-12)
when all the error-codes are displayed, the sequence finishes with an "ON" LED
blink of 3 seconds
the sequence starts again
Example of error buffer: 12 9 6 0 0
After entering SDAM, the following occurs:
12 short blinks followed by a pause of 3 seconds
9 short blinks followed by a pause of 3 seconds
6 short blinks followed by a pause of 3 seconds
1 long "ON" blink of 3 seconds to finish the sequence
the sequence starts again.
