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....

Are there any LEDS lighting up on main board? There should be 2 I believe.

Re: Xbr55x930d. Has backlight and sound but no picture

This sounds all too familiar, if you have half the panel connected to the tcon you should see half a picture. If the panel is completely disconnected then no sub voltages will be present on tcon. I...

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

In my experience any of the 4 ribbons disconnected will cause this. They all have to be connected. The OLED does not work like a conventional LCD screen. Data transmits from the left cable and out...

Re: e701i-a3 no picture but backlights

OK that black line on the top lower quarter of the screen. It looks like it extends off darker on the right side. Even though the picture in the post 916 is upside down I would say there something...

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

The reason you're getting a dim picture is because DRV_ON is enabled. However there is no data being fed to the panel. The fact that you don't have any white vertical lines Is a good sign because...

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

So the LG logo is staying lit without any jumpers in place? It seems to respond by pressing volume up volume down and input buttons? I can see you are getting some kind of a picture can you put...

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 50" Plasma PS50A457P1D Grey Blotchy Cloudy

That sounds like they are shorted. One or more will have lower resistance then others. But for good measure pull the middle leg on all and mind the.mosfets that are shorted.

Also I read that you...

Re: Samsung PN43E450A1F 43" Plasma - with "line offset"

Good to know! Buffer ICs can fail in other ways besides shorted. Had one on a LG that was actually open. Caused a no picture but had prime.

Re: Samsung UN48J5000: Backlight Strip Burn

I would imagine if the LCD panel were installed inside out you would have the SMD components facing the inside of the TV and not the outside of the 2 boards attached to the LCD panel. Also you would...

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.

Re: Lg 55eg910v oled tv
