Re: LG 47LS4500 picture issue

That vertical band band corresponds to one of the TAB bond/flex cables (second one in from the edge). You can try putting some pressure on it but likely not repairable.

Re: Vizio M43-C1 No Backlights

ON/OFF (BL-ON) signal not going high. Should be at same level as PS-ON. Signal comes directly from the processor.

Re: M43-C1 1 long blink 16 short

This TV doesnt have blink codes. Likely a bad main board. I have purchased used ones with the same failure.

You can reprogram the eeprom with a cheap ch341 usb programmer.

Re: Hisense 55'' Issues Mainboard or Power Supply?

Any issue with the backlight is usually the LEDs failing or intermittent. You can try turning down the backlight level and see if they stay on longer. Running at 100% is what causes them to fail.

Re: Samsung UE46D6750 double image problem

Power up the tv with only one side connected at a time between the tcon and panel. If one side is good, you can try the tape cutoff method on the bad side.

Re: TCL 55S403 No picture. Sound and Backlight OK.

With a TV turning on with backlight and no video, the first suspect is the tcon board. Some newer models don't have tcons. To make sure it's not the panel, power up the TV with only one ribbon...

Re: Samsung UE50EH5300 - bad picture, helping to diagnose for a friend

Horizontal lines are panel issues. Google for the Sony tcon training manual. If one side displays a clean image, it is repairable with a workaround. If both sides are bad, its not repairable.
