LG 3D TV with picture failures

[bilian]

Hi there. I have a 3D TV LG 42lw650s that one day stopped working. Attached images of what happens when turning on. The t_con board is not, since I changed it and the same thing keeps happening ... What could it be? Thanks in advance.

Most likely the LCD panel itself - as the majority of LCD TV failures are.

that could be the main pcb too...

It 'could', but it's MUCH more likely to be the LCD panel - as I said, the vast majority of faults are the LCD panels, at least on the 'better' makes.

3D was a TV fad that certainly came with much hype, and then rapidly left without a whimper.

probably because manufacturers couldn't settle on a good way to execute it. they got the display and transmission part of it standardized, but the viewer's glasses (passive vs active (requiring batteries and some method of synchronizing)) and the limited viewing angle were still limitations that left people less than "wowed" by the technology

I have fixed!!!! I have done reflow on the main board, 12 minutes at the oven on 230 ºC. Very easy fix, I was very dizzy with this problem haha. Thanks you all guys
