Re: Cello C55ANSMT-4K CURVE V2

I think U4 is the same.
U25 has the screen type so wont work.
I had one bricked with u4 being the fault.

Return of the BadCaps

Anyone else noticing higher volumes creeping back into a lot of budget brand tvs.

Those MEGMEET powersupplies are particularly prone.
assuming, of course, the LEDs dont go first.

Re: Is this an LED problem or panel problem?

Be interesting to see what's under the screen.

I had an LA series by LG a few years back that had pretty much caught fire. By the time I got to the tv there was no picture. But when taking it...

Re: Samsung UE55JU6470 wide vertical stripes on screen

Screen has failed. Likely has been cleaned fairly recently and the moisture has ran down the screen and killed a COF.
