TV issue Hi, just curious if you might know what is causing my Panasonic LCD projection to have about 4 spots on the screen that are either red blue or green. Kind of annoying. They started to appear about 6-8 months ago. Seems to be getting worse. Your thoughts?

There are many causes for spots on top of an LCD rear projection tv, you are probably in the first two cases, both require part replacements and repair job.

If the spots are faint blue, green or pink shadows, then it can be a problem with the anti polarization panel placed on top of the LCD.

Similar spots (colored shadows) may be caused by a problem with the light engine, in that case the fix will be expensive.

If the spots are bright lights, like an aura, that is a problem with the color wheel.

Problems on the light tunnel can cause static gray shadows.

If the spots are static dark stains than that is lcd liquid, the LCD panel must be replaced.

I have colored spots appearing on my screen when the TV is on. The spots are 2 to 6 inches in diameter and always appear in the same locations at various places on the screen. The first spots I noticed...


the light engine (optical block) is failing. there are lcd panels and light filters in the light engine. the problem your having is that they over heated and the image is burnt into the lcd or light filter. my be caused by a failing fan or just it's life span. the lcd panel or light filter are done for. you can keep calling panasonic and bug them over and over and they may send you a new tv. sony sent me one after 5 phone calls. i had the same problem. hope this helps.

I am getting 4 color spots on my tv its not the lamp i just replaced it and they are still there


The spots are due to the LCD driver panel with faulty software on it. You will need to contact a Panasonic servicer so they can perform a software upgrade to the driver panel. Most servicer's should be fully aware of this issue and the needed tools to repair it. Most likely you have blue, red or green circles.

My Sony Grand Wega LCD TV currently has a large blue spot on the left side of the screen when powered on. I have changed the lamp, but this did not solve the problem. Could this be caused by bad component...


Hi,
I'm afraid, it is problem of optics unit block (light engine), there are 3 LCDs red-green-blue for color picture formation and blue LCD sounds bad, please call local TV tech for fix.
Thanks.

Light green and pink spots on my hd tv!!!


Hi--Bought my panasonic pt-52lcx65 on sale for $2200 in 8/05. Replaced the lamp for about $300 in 1/08, just prior to Superbowl. Admittedly, this was to be expected after family members watched lots of tv over 30 months. However, two months later the blue spot emerged in 3/08, and red spot emerged 5/08. Set looks decorated by a Andy Warhol or Van Gogh wannabe. I'm looking for a fix it solution. Dr. Bob Heiliger, Lebanon, OH.
