UPDATE! HAVE TV, But have lines...

I replaced the power board, and now have power and screen. I now have a good pic except for the top part of the screen has black lines in it. Any ideas?

Remove and reseat the ribbon cable for that part of the screen on the Y-buffer.
POWER MUST BE OFF WHILE DOING THIS!!!

Re: Samsung pn50b550t2fxza

Just reseated cable. No change.

Re: Samsung pn50b550t2fxza

Cable alignment is critical.
The cable has two positions it will go into.
The first is the obvious, intuitive one. It's not that one.
The second one gives a light "click" feeling. It's that one.
Make sure you feel/hear the click.

Re: Samsung pn50b550t2fxza

I tried it a few times... i'm pretty sure its in correctly. Could this be a ymain/xmain issue yet?

Re: Samsung pn50b550t2fxza

No. it worked fine, then just died.

Re: Samsung pn50b550t2fxza

My buddy who owned it before, replaced the Y sustain board with one of Fleabay before giving it to me (board didnt fix problem).. but didnt save his old one. Could be that board i suppose.

Re: Samsung pn50b550t2fxza

Did you replace the Y-buffer board or just the Y-main board?

[Digglr]

Re: Samsung pn50b550t2fxza

He told me just Y main/sustain.

Re: Samsung pn50b550t2fxza

I don't know what to suggest. Is that ribbon cable undamaged? No wear or tear on it? All contacts clean?

Re: Samsung pn50b550t2fxza

Do you know by chance the Vs and Va voltage numbers I should be getting? Or where I can find them for this model?

[Digglr]

Re: Samsung pn50b550t2fxza

I tried the Samsung manual link in the sticky, but its dead.

[Digglr]

Re: Samsung pn50b550t2fxza

Still cannot locate the Vs and Va specs... anyone know of a site or link?
