Vertical bar on Daewoo Plasma screen

I am getting a vertical black bar on my Daewoo Plasma screen which comes and goes. We have a 46" LG plasma, with vertical lines in a variety of colors: red, blue, orange, green, you name it. We have 3 lines on the right and 1 on the left. Please help!

    We're having a similar problem with our LG plasma (model# DU-42PX12X). We had absolutely no problems with this TV until a couple of days ago when suddenly half the screen got vertical bar lines of various colours.  Sound works great and so does the other half of the screen, but the TV isn't much good to us the way it is.  We haven't done anything yet because up until reading about the dry sockets, we had no idea what it could be.Thanks for any assistance.

    I just bought a 50" Panasonic Plasma HDTV (TH-50PX75U). I saved $60 buying an "open box" special.




    I'm guessing the reason it was on "special" was that the original owner encountered the issue I'm having.


    After being on for about 1 hour... a set of black bars appeared on the left side of the screen. There are two of them (about 1.5" each / about 1.5" apart) on the left side only.


    They appear whether I'm watching DirecTV satellitel connection or DVD playback.


    This is not something that can be adjusted by me is it?

I have a LG 50PX1D-UC plasma TV with a black vertical line


You could have a Driver Board that has a loose connection or a Ribbon Cable that has a intermittent connection to the Plasma Panel, or a defective Plasma Panel. Either one could cause the problem and I would recommend only a Qualified Service Person to check it out.
Here is LG's Customer Service Number. 1800-243-0000. They could direct you to a Local Service Facility.
I hope this helps,

Black Vertical line appeared on my Daewoo Plasma


Bad connection somewhere along the bottom or top of the panel, there are boards most likely along the bottom of the screen that control vertical drawing, a connection that breaks as it is heated up sounds about right. check the connectors along the bottom. Be very careful because if you wreck em the screen is junk. The connector that will be at fault will be in direct line with the black bar.

Vertical bar on Daewoo Plasma screen


The main problem of this model is VPB (video process board) and the reason is they build in it SMD capacitors and they are always crap.First thing that you guys should do is to replace them all but not with SMDs,get a normal capacitors same values.And of course replace all capacitos on PSU.Parts are cheap to buy about 30euros,work on the PSU is easy,only the VPB is tricky but it can be done.It only takes time but belive me don't even think of board replacament its cheeper to by a new set
