Samsung pn50b450b1dxza horizontal lines

[debugger]

This set had no picture all voltages were good except vs. I unplugged the y Main and vs came up to 209. I replaced the y main and the set fired right up.
The set has horizontal lines. I have cleaned and reset the ribbons, with no change. Give me the bad news about the panel or could it be something else.

Textbook mis-seated ribbon. You say you have reseated them but they are really hard to get right. I would pull out that one and try it again.
Looks like you also have a thin red line on the right of the panel, THAT is a bad panel for sure.

Ok Ill give it another try. Yes I have 1 vertical line that changes color with the scene. Looking like I may have some boards to sell. Thanks Tom.

I finally got the ribbon seated right. Too bad the vertical line is still there. I am disappointed that I have to part it out. At least I know all the boards are good.

Re: Samsung pn50b450b1dxza horizontal lines

I'm not so sure you have to part it out. I've sold a plasma before with a bad vertical line. (It's a rare fault; it's one of the few panel failures plasmas have, vs LCD which has a high panel failure rate.) I got about 30% less than I would normally, the person I sold it to just wanted a big screen to watch football on it. I still made a decent profit, as the TV was cheap (the seller didn't mention the line.) It would bug me, I couldn't use a TV like that, but some people don't really mind. Plus it's pretty faint.
