Samsung UE49KU6500U boot loop

[signedupfordownload]

Hello,

My Samsung TV had a black patch on the left side of the screen for a while. One night it shut off and then became stuck in a boot loop. I initially believed the back-light was the issue and replaced the LEDs but it still boot loops. I've since replaced the main board and the issue persists.

With the main board unplugged, it powers on and the back-light comes on. I've tried the tape method but I gave up as I don't know what pins I need to cover.

I suspect the panel itself it broken but have no multi-meter to test. Is it worth investing in one to test? Apologies for the lack of information, I can provide more as needed and pictures too.

Thanks

The black patch may have been caused by possible damage to the panel itself, most likely a minor crack somewhere along the edges of the panel on that side of the tv or the COF over heating and literally burning the panel, either way, my guess is the panel has finally deteriorated to a point of no return.
