This, sadly is getting to be a very common problem with all Projection LCD TV's
Colored Blotches on an LCD Projection TV are usually caused by defects or marks on filters or lenses or one of the LCD panels themselves which are all located in the light engine (or optical block) First confirm that the lamp or main lens is not discolored by removing the lamp (unplug set and let cool before removing!) and inspecting the lamp itself and the lens that it shine onto. The light engine is an expensive part ($600-$1200) to replace and requires major disassembly. Get an estimate -Be sure to vote/rate me if this helped Thanks!

Let me know what actual model number is; one listed is for a newer set.

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.

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

sounds like its your optical engine block. if it starts to leave green spots or white dots that keep on coming then its your optical engine. let me know I know someone who repairs the optical engine block. leave a rating after you find out.

power on.
press and hold the down volume button on the TV and the split button on the original remote together for over 5 seconds.
It should reset the timer and the lamp led should go out.
