My rear projection TV has color spots in the picture, most noticeable on light color picture


What is the make and model of TV. If it is a Panasonic that has different colored spots such as pink, blue etc. Then you need t6o contact Panasonic as this is a memory reset that they have to perform on the LCD driver board. Other brands of LCD projection sets that have spots that appear all over the screen mostly on white back rounds are almost always dust that has settled on the LCD panels. This requires a technician to clean the LCD panels if possible.

TV issue


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.

Pink and Blue Spots


Sony guarantee the consumer to replace the optical block assembly for thousands of dollars in parts and labor every four years or when the pink and blue spots appear every time. Then replace the optical block assembly again and again every time the spots appear.

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


Tiny particles of dust on the light engine lens can cause this (and was a service call for me about a month ago), or possibly the expensive light engine.

We Cleaned the optic block as was instructed by another post. But now we have a wide ribbon of light yellowish to the right of our screen. Could it be more dust to be removed or now we can see there is more problems then we thought? Over all the screen looks much better. But a far cry from when it was new.
