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 problem is most likely the panel itself where the ribbon cables are corroded. There is however the also possibility that the tcon connectros need A clean.

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 Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, 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

You will need two STK392-120 convergence IC and about six 6.8 ohm 1watt convergence resistors you can get the parts at the following link and they provide free step by step instructions with pics.

need to replace the convergence Ics STK392-110 there are two of them. Also check the six 2.2 ohm 2watt resistors

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.

have a nice day

If it goes all the way from top to bottom, you have a bad panel. much to expensive to repair

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.
