The tv image is showing in three colors....Almost ghost like but in three colors. I checked my connections and tried my blue ray player and the image is still messed up....I did press the magic focus...


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 projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

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 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

In convergence mode, I can't move red line up and down, blue line works fine. And my Toshiba projection TV shows double layer vertically.


once you have exceeded user intervention, condsider that the convergence boards are on the way out and will need replacing and retuning correctly Not a DIY as it requires special tools circuit diagram and knowledge of HT power and radiation protection.

Goes from normal to weird colour saturation blues and reds seperated and ghost double images


It sounds as if the video card driver is on the blink. Try going to Toshiba.com and look for video driver upgrades for your system and download. Let me know if that works.

Thx

Ghost red image


If you are connecting via HDMI, try either getting the firmware upgrade from the Philips website or switching to Component (Red, Green and Blue) cables.

PLEASE HELP (Three Ghost Images)


You will need to have or change the convergence correction driver IC's. There are two of them in this TV set. Not a fix for a novice I'm afraid. If you have no solid state repair experience, play it safe and call out a pro to assist you in this repair.
