Default Samsung Plasma Tv with black vertical bar.

Someone has a Samsung plasma tv model#Pn50a400c2dxza with a black
vertical bar on the right side of the screen from top to bottom, and this tv is
two years old. Can anyone offer any solution for this problem?

Usually a bad panel. Sometimes fixable, often not. Would need a picture of the inside of TV to tell.

No, it's not the panel.

See this video:

It is possibly fixable.

It depends on the design. Some TVs have the X buffers off-panel which are replaceable - whereas others have the X buffers on the panel and replacing them is not possible.

Yea, but as the guy in the video points out, it's not the actual panel, the X Buffers were on the permanent cable coming out of the panel, so it's still not fixable, but there is nothing technically wrong with the panel itself.

Suppose, but I'd still write the TV off either way, as the panel+cables is going to be very expensive.

You don`t know if it is a board or the chip on the ribbon cable. I have repaired over a couple hundred tvs so far. I learn something new on each one. Not always pattern failure.

I have had two plasma tvs with the vertical bar as said above. One was a burned chip on the panel ribbon cable.

The other had a bad board and a failed chip on the ribbon cable.

The chip looked ok but when I replaced the faulty board it still had a vertical bar.

The real problem here is people will make the tv dead (does not power on or blank screen) because everyone knows not to buy or take a tv with a vertical bar unless you need boards.

The one I have is a samsung and I use it for testing boards and learning.

In one case I have fixed the black vertical bar problem on an older LG plasma. It was just a resistor on the FFC that had a cold joint and had separated itself from the board. Tapping the bottom of the TV would sometimes fix it, but never for long. Fixed it with a bit of solder and a soldering iron.

Older is the key word here... as in 2005?

I think the older tvs were less of an issue and more repairable. I have a few of the oldie but goodies and I will not part with them.
