Hi , i am working on a PN50C450B1DXZA when i hit the power button the screen flickers once but doesn't come on. The power supply will stop delivering power to the logic board after a few seconds, if i don't short the pins to turn the tcon board on. The tcon board and the y buffer board has been replaced from supposedly working parts. The next board on my list would be the x and y sus boards, would either of those boards cause the psu to turn off , like a disconnected tcon board?
Also how do i know if the panel is shorted out ?
