TV doesn't turn on, standby LED blinks in a sequence
Dear repair cummunity,
I have a problem similar to many other users in here and I know that Samsung does not officially support blink codes but the fact is that obviously some defective sets emit what closely resembles a blink code. In my case the standby LED blinks once long and five times short as soon as I start the TV, either with the remote or the "joystick". The TCON card has two tiny blue LEDs that are on, and blink once each time the blink sequence restarts. I believe that the backlight LEDs are fine as they turn on when I disconnect the cable between PSU and main board. My model is a ue48ju6050 (bought in Germany). I have visually inspected the electrolytic capacitors, the aren't bulged. The PSU delivers 12.9 V instead of 13.0 V. I guess it is within an acceptable range.
Basically I would like to know whether to replace the main board or the TCON card (or both), or even better replace the broken components . Without service manual, it isn't obvious.
Any idea? I would be extremely grateful!
Here a general view of the interconnected boards:
Ist dies eine gute Frage?
