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.

54inch Hitachi TV has double figures and colors red, yellow-not normal. Set approximately seven -eight years old. Lost remote control and direction book in moving. Is the set worth getting fixed? Generally...


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony2_bing.gif,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer2_bing.gif, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms

  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

You can see some more examples and find a fix here

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.

Sony KP-51HW40


I had the same problem with mine 2 years ago (TV was 1.5 years old at that time) I had extended warranty on TV and it was fixed by Sony at no cost to me. Now yesterday I have another problem with it. All of a sudden screen went BLUE. No Sound either. It could be the CRT (That's what I read here) Out of luck this time. Will call local Repair shop (70 miles away) and see how much it will cost to fix it. Good luck.
