TV Fault

There's a crack in the glass just up from the bottom left corner. The panel is covered with a grid of thin transparent conductive traces (typically indium tin oxide, ITO) that connect the drivers around the periphery to the individual pixels (LCD or OLED). The crack has broken the traces so the pixels downstream from the crack (vertically above in this case) are no longer connected and remain dark.

You need to replace the panel, but unless you can find a donor TV with the identical panel it's unlikely to be economical to repair. I'm afraid it's new TV time.

IMHO it's had it.

You could try reposting in sci.electronics.repair in case anyone has successfully fixed this sort of fault.

I was wondering what might fit the symptoms, and I believe you have 100% hit the nail on the head.

Since the cost of a TV is about 90% the LCD screen, unless you want to find another one with bust electronics and spend a day for an uncertain result, put it in the trash

at 10 years old it doesn't owe you much.

Yup, the LCD is physically broken - look close you will see fine cracks.

Yes, but, typically the new panel will cots more than the TV!

True, but sadly that means dealing with the modern spyware / ad slingers that modern TVs have become.

Many thanks for the replies - good to know, save wasting too much time on it.

Shame, it was a good telly, excellent UI and a really good picture. Previous owner discarded it as it could no longer do Netflix etc. I tried to persuade him to get a firestick etc, but he wouldn't have it and bought a new OLED.

I am all in favour of keeping old gear going, but part of that is knowing when its really reached end of life
