Re: Lg 60PZ550 no picture

or you can do some guessing, my first guess would be maybe a tcon issue but it's just a guess without testing.

Re: Sony Bravia KDL-70W850B T-CON board / software update issue

ok, does it come back on by itself after it shuts of, like on 10 seconds off for whatever time then back on for 10 seconds or it just shuts off and stays off?

Re: Philips 55PUS6262 no picture

it seems like you need to figure out why a little pressure on the ribbon cable fixes the issue, wonder if a little paper shim or sum such on top, not where the contacts are, would do the trick.

Re: Philips 55PUS6262 no picture

Re: Sony Bravia KDL-70W850B T-CON board / software update issue

from all i read, some did fix this issue with a replacement mainboard, I think I overcooked mine and the replacement for my model was 150 or so, seems like more than the tv is worth, I'm curious if...

Re: RCA led50b45rq tv backlights flash then shuts down

oh crap, hate when that happens, they are way too flimsy, seems like they could make them more durable but they probably don't want to spend a few more pennies during manufacture.

Re: LG 42LE4900 no backlight, possibly no display

if no joy, maybe try to run the powerboard as stand alone, to see if you can get the backlights up, this one is unfamiliar to me so I don't know the procedure.

Re: RCA led50b45rq tv backlights flash then shuts down

Probably time to carefully strip it down to inspect backlights. You can if you like, replace individual backlights, possibly with some from a previous salvage if they match, more are likely to fail...

Re: Sony Bravia KDL-70W850B T-CON board / software update issue
