If it is a picture tube type TV not a plasma or lcd try degausing the picture tube. I think Radio Shack carries degausers or find the plans for one on the net.

If bowed like )( it is in the pincussion circuit or a wave moves up from bottom to top in what you have it is a bad input filter in the power supply. The wave if there will look like a ripple moving either up or down in what can be seen on the screen.

Picture cut off on sides, how do i shrink picture to screen?


If model listed is correct the problem is in power supply or vertical or horizontal circuits.

If cut off on sides (horizontal) and bowed on sides it is a pincussion problem. IF short top and bottom a vertical issue--if both it is in the power supply.

Model listed is rather old and parts may not be available for it.

Hey I have a mitsubishi vs-80803 i have picture but it is a bit bowed on the right side and bottom of picture (black curvature space showing no colors or picture) maybe the convergence needs to be reset?...


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

BOWED IN SCREEN/PICTURE


the problem is called pincushion

usually fixable not by anyone without electronics background

guessing around $150 you have to decide
as long as it has a good clear sharp picture its worth it

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

This mis probably a cold solder connection in the horizontal circuitry called the pincussion. Theres a couple of coils and resistors that overheat from time to time and the solder connections get loose. Not really for a handiman has this tv has hi vboltage inside even when turned off. Shouldnt cost an arm ans a leg to fix if the repair shop knows what they Are doing. Good Luck
