Re: Samsung plasma TV not starting PS50B 450B1DXXY

I'm going to trick the power supply to start up fully as i think the mainboard is not sending the write signal.
All caps are fine and no signs of crapping themselves. All components look fine.

Hi
I was given this faulty 50" plasma tv.
It has a red standby light. When i press the on button i here a 1 click and the screen flashes white then off and i here the samsung chime then it clicks off.

I can see a green light flashing on the x driver board.
I turned the tv off and waited 15 min, then disconnected the y-z sustain and buffer boards and turned it back on to see if the x driver green light stops flashing but it makes no difference.

So i think the problem is in the power board (BN44-00274B MODEL P08050A).
I reconnected...
