Question about LG DU-42PX12XC 42 in. Plasma HDTV

Red lines on right hand side of the screen now no picture on right hand side!

We started having problems with this set about 4 months ago with the red lines on the right hand side of the screen. Last month multi colored lines started appearing on the left hand screen. Now the left hand screen is completely blank? Right hand side still works with red lines still present.I was wondering if replacing the driver board would fix both of these problems or just the red lines. I was an electronics tech with the navy so replacing the board should be no problem but I have no experience in the plasma field. Any thing I need to look out for?

    I agree with your assessment but the only repair kits that I can find are for the series 7 panels. Totally different tv. Boy I would love to find a subsidized kit like that for my model. If you know of one and who carries it I would definitely buy it.

I'm not an expert, but I have determined that the vertical bars that are often red, sometimes blue ... and sometimes both ... are related to a bad control board. I've also read that a common fix is to buy a repair kit with includes the ysus, zsus and control boards ... all replaced together. My experience was that after a month or two with the 1.5" wide stripes, that you eventually loose the entire picture and have sound only. MIne comes back, but won't stay working for very long and the stripes are always there (buy used to fade and flicker sometimes). I'm planning on replacing the control board.

Red vertical lines on right side of LED TV set


It is likely the main board that processes all signal to and from the display panel (entire front screen unit).

It is also possible it is the display panel itself which is fatal.

The panel is almost certainly bad. The only fix for this is to replace the whole panel which would cost more than the whole TV.

Vertical line on side of LCD TV


Modern televisions have screens divided into sections. Each section controls all the rows in its area, and it is controlled by its own video separate video driver. If you are missing a line in a section, then a problem has occurred with the driver board in that area. It will be pretty expensive to fix, I hope your warranty has not just expired!

Insignia(samsung) 50" plasma Vertical red lines


I would take it back. I know from purchasing an Insignia LCD from them a while back, the TV just died after about 4 or 5 months. They ended up offering me another TV or with store credit. I took the store credit and chose another TV. I also did not have a warranty. I was told since it was Insignia (which is a Best Buy house brand) that replacing it was not a problem. Good luck.

Red line on screen


I had the same problem -red, vertical bars along the right side of my Samsung 42" Plasma- and this is what fixed it: Removed unterminated cable.  
I had hooked up an HD video camera to the set about two weeks ago.  While I disconnected the camera I left the other end of the connector cable plugged into the T.V..  As I've since learned from friends who work in television, this is what's called an "unterminated cable" -meaning one end is unconnected.  It can lead to problems with electrical interference and appears to have been the problem in this case;  When I disconnected this cable from the T.V. the red bars went away.
So, check your cables.  Make sure everything is properly connected and get rid of anything that might be picking up interference.  
Hope this makes sense.
