THis set is notorus..bad to converge ...here at the shop seting the convergence takes up alot of my time... you may have to get a technician to converge in factory or service model.. this is something a non tech should not due "you can mess it up good" there may be a convergence amplifer board problem too. suggest getting a tech to chech it out. IF you can converge at all is a good sign that it might just be adjustment. average repair for this is 100 to 200

Can not get the focus grid to line up correct green adjusts fine but blue upper left corner will not adjust and the red grid is way off and will not fix


All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

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. In some cases the TV will also not show any video. 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 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 pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

Look in users manual or internet you should find how to access service mode, this is different from regular setup CONVERGENCE, this involves getting into changing parameters to tweek convergence, even after amps are changed.

Try to describe problem better----is picture concave or bowed with colors out of place or is is just not straight?

If in doubt go into customer menu and select convergence and then advanced(instructions will be on screen) it will bring up a grid of lines--what you are looking for and I need to know is is the grid not square or are there red or blue lines with or without a bow in them?

The more you can tell me the better the chance I can help you--I am in California and will be here for the next few hours.

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.

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
