Samsung ps51d550 plasma tv repair help

[jshhh]

Hi all,

I have an old Samsung ps51d550 that would power on with no picture. I was testing the voltages on the boards based on some advice I'd seen online, I took off 2 of the boards to try test the mosfets, but couldn't really get at them...I left it a while, came back and reinstalled the boards to do some tests and it started smoking. Looks like it was coming from this ribbon cable (see attached picture).

As you can see, im an absolute novice with this kind of thing but I don't like paying for repairs or buying new stuff if I can fix it cheaper.

do you think this is still fixable? Any advice where I should start if so? I should've done more research before starting to take stuff apart and test so now I'm looking for some help to see if I can get this done cheaper than getting a replacement 😅.

Thanks in advance for any help.

Hello
My first suggestion is that you might want to look for a replacement cable
If you dont know where to find you could start with AliExpress
They have many of those flex cables available for purchase

To create this burn or smoke I would assume you have short to ground somewhere in what ever parts are related to that cable. that or the cable itself was just shorting two wires internally.

that is the current suggestions that i have for you
