I have a problem and hope for help:
Samsung LE46C750R2Z as always left in the stand-by.
TV turned on, the red power LED (bottom right) continuously blinked in seconds (1st confusion) Also, the TV did not respond correctly to the buttons on the remote control.
Wiring diagram please
I have removed the cable between power supply and motherboard, the lighting goes on very fast and stays on
I think here is the problem of the motherboard or?

Please help
Thank you very much
