Hi everyone!
Just wanna know if there is any progress in this repair thread.
I am having the same problem just like joe joe. PSU unit BN44-00204A is tested
ok. All voltages remain constant when PS_ON and / or VS_ON enabled.

I suspect the culprit lies on the Main Board BN41-00982B. Unfortunately, I haven't found schematics for this mainboard. Does anyone know replacing the eeprom will solve the turning on and off problem?

Thanks in advance for any help!
