Re: sharp lc-60le640u
Tcon is good. Panel is good. Sharp will fail if tcon cables are messed with while powered up. That's probably what happened. I suspect mainboard. Try heating up the mainboard with a hairdryer....

Re: LG 55EC930V OLED - 3 Second Power No Display

Re: Sharp Aquos TV LC-60LE644U
Sounds like mainboard failure. Ot locks up due to bad connections under the main processor or may be RAM related. Either way, replace the mainboard and you'll be back in business.

Re: Samsung UN48J5000: Backlight Strip Burn

Re: Un50j5200afxza
Check on ohms test with a voltmeter.. Those tan rectangles caps. Are any of them reading low ohms? 0 ohms? Compare these readings to the working side of the panel.
