Top half of the screen is normal colour and the bottom half yellow greenish


Depending on the brand, it's likely that the color guns are out of alignment, or some of them are faulty. If bumping the TV has any affect on the picture, this is your problem. If the TV is a newer TV, this should be covered under warranty. If it is past warranty, the parts are available from the manufacturer. It's not "easy" to replace these parts, but it is doable. Good luck to you!

Picture looks like it is warped at the bottom and top of the picture. Have picture, no problem there, just not a centered picture anymore. Looks like the top of a half moon on the top and botom.


This is a very common failure on these projection sets and a fairly simple DIY fix. All projection 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 images of convergence problems.

Wavy picture at bottom half of screen looks like two different colors, top half convergence looks good bottom half of pictute looksbad . Can it be vertical coil on two piture tubes not being drivendue to...


Projection TV sets have two very common problems listed below.

Problem #1) 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
*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
