I'd be tempted to say loose panel connector or digital board issue. Reseat the panel connector for that portion on the X buffer. Only do it with power disconnected or you risk further damage.

Ok ill try that, when you say digital board do you mean the main board or the Y-Buffer? also does it look like a bad panel or no?

Control board = digital board. Sort of like LCD TV T-con. Usually has a blinking light on it.

You should also try this test to rule out main board:

I'd say panel failure is about 25% likely on this (not seen it before personally), if you had a single pixel line or dead bar with pixel lines then I'd call panel 100% dead.

Well I was having success with the lines I got them to disappear, but as I was about to close it up I heard a pop and I seen a spark and after inspection I see what blew, I'm not sure but it look like to be a capacitor on the logic buffer E which the buffer looks like its not replaceable cause the ribbons to the screen are attached to it, anyhow I took a picture of what blew you can see its burnt in the picture also the number on the board of the failed part is C2555 is that replaceable by soldering a new one and if so what value is it? right now its just a black lit screen.

Other values are in parallel with it, they are probably the same. Remove another one and test it.

Actually its the The fuse in my Samsung Plasma E-Buffer board is blown because of a power outage in my house. I jumped the fuse for a few minutes to see if the set was fine and it was. How safe is it to just leave the fuse jumped? would it be ok? If not I have included a picture of the fuse.

"RISK OF FIRE. REPLACE FUSE AS MARKED" gives a small clue.

Ok, any tips for unsoldering the faulty one and soldering the new one in place? I have one here from a digital board I don't need its exactly the same specs and same fuse. I assume its going to be had with an iron that can only heat up one side at a time. I'm scared of lifting the pads or burning them. Any tips? how about soldering the new one on top of the old one? Do you think a heat gun would work to melt both sides at the same time to pull off the fuse with tweezers
