    You have a bad convergence IC's in the TV set, or it is on its way out. It is a single IC that controls all six channels of the convergence correction. It is labeled STK 393-110. You can get an original replacement from HERE You only need one of them

Projection sets have two very common problems.

The first common problem is convergence

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,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

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

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*No Audio/Video - TV Shuts down - May also make a constant 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

Red green lines across my screen on 51 inch tv hdtv


If you cannot align those crosses, then the convergence section is damaged. should be repaired by a qualified technician, its a big job.

Color seems to be pealing up from the bottom of screen



If the screen is bouncing...expanding/shrinking you need to get a repair kit from www.TvRepairKits.com

If your screen looks 3d in color, has a stationary bow, or if you can't adjust one or more colors from the "convergence" menu you need to buy a convergence repair kit. You can get one from the same site listed above. 

Hope this Helps,

I believe its the vertical output IC. Diodes would tend to blow fuses . I would replace the vertical output and see if that takes care of the problem.

You have two bad convergence integrated circuits and possibly an open resistor or two in the supply.
