Re: not sure, but looks like blue and red shadows around...

Al, bring up your convergence grid (look in menu for it) and I think you`ll find that the set is out of convergence, if you can adjust the red up & down and the blue up & down your ok, if they won`t move in one or both directions the convergence IC`s will have to be changed out, hope this helps, BMW Rider

Lots of Blue shadows off to side. concaved picture almost

HI, this is a failed convergence chip that is located on the convergence board. it will need to be replace ASAP. you can just replace the chip or , you can order a new board.

Replacing the chip can be a rough job if you don't have tech experience. if you are a fluid tech and you can solder and know your way around a circuit board, just replacing the chip will cost less. if you are not an experienced TV tech, i recommend a service call to the nearest TV tech to replace the convergence board.

Red shadows of words on screen of projection TV

you have to go into the menue, and go under video settings, under advanced, then into convergence, when you get the white lines all over the screen, follow the directions and adjust the red so it lines back up, other wise , take the front bottom panel off the tv, look for the 6 little nobs, look at the ones on the left, they should agjust the red, thrn the top one untill the red is focused back in.

Wave at bottom of screen with green and pink shadows

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 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.
