Replace the convergence ICs and feed resistors. You can get replacement ICs and resistors at the following link with installation instructions. If you leave them a email with your model number they will tell you the correct ICs and resistors for your model set. Heres the link.

Our tv looks like a 3d tv. Out of focus


Try to adjust the convergence using the original remote control of your tv, then go to the convergence setting menu, then go to convergence section. You should be able to move the blue and red in any directions right, left and up, down. Or if you cannot move them far enough the convergence chip is defective replacing the bad convergence chip will fix the problem. Feel free to send feed back good day and best regards.

PHILIPS 60PP9202/17F - Left/Right convergence doesn't work for Red/Green or Blue. Up/Down convergence works OK - What might be the problem?


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.
