Philips 50PF7321/10 no image or sound
Hi all, greetings from Turkey.
I have an old Philips 50PF7321/10 and it stopped working.
When I plug in I hear two relay clicks and after a few seconds I hear another one. Green light is on but no image or sound.
I tried few things, here are the results:
I dissconnect connectors of the X-Main and Y-Main boards from the PSU board and measured the voltages. All are OK. (I can post the readings if you want)
When I connect them problem starts. Many voltages are missing or wrong and the led (LED8001) blinks 5 times. Alarm codes on the boards says Vscan for 5 but it was OK when X and Y boards was removed.
When I connect them one by one the led stays steady but no image.
The PSU board was completely replaced some time ago by the previous owner.
I could not understand if the problem is on the PSU board or X or Y boards.
Could you help me to find out the problem?
