Its recomended to replace both at the same time as each IC controls one color and half the green so when one goes out the gree tends to weaken the other. You can get them with free instructions at the following link.

The red will not line up when it is in the


You have a yoke and screen voltage issue with your red crt tube. If the red moves but not enough to do the convergence then you may be able to adjust the red crt. If the red doesn't move at all when you try to do the convergence then you most likely have bad convergence IC chips that need to be replaced. They aren't expensive, the last pair I did cost $36, but it involves taking the set apart and doing some tedious soldering. If you have no experience with this sort of repair you may want to go to a shop, They will charge $300-$400 to replace the IC chips. If you want to try this yourself post back and I can help point you in the right direction.

Convergence problem


Your set has a convergence problem which is a common issue.

Take a look at this solution posted earlier on Fixya. It worked for me.

Red bowed lines


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.

Magnavox rear projection


If the red converge will not line up, then there the convergence chips are actually bad - the repair will cost around $700 if you go through a Magnavox authorized service center. I would look at posts by Slinteriors in the Philips or Magnavox rear projection sections - he has some ideas on generic chips that might be had for cheaper.
