SOURCE: color spots on panasonic projection screen

Move anything magnetic or any sound producing electronics away from you television. This includes stereo speakers or alarm clocks. Give your TV 30min. to 1hr. to cooldown completely and see if that fixes your problem.

SOURCE: Hitatchi 52" rear projection TV has blue spot in middle of screen

Hello :
I suggest u retrace you the steps u took to replace your lamp make sure no foriegn objects got on the prism where the light shines throung the optics engine, if you remove the lamp compartment througly. If you had a perfect picture prior to replacing the lamp, then retracing your steps you might find something that does not belone. One final note: Did you purchase the right lamp 120watts anything higher than this wattage could damage your optics engine. I suggest never vacuuming the compartment because particals fly around from the suction and could get on the glass of the color wheel asembly.

We have a blue spot just below center, not extremely annoying just there. Light engine was replaced 2 1/2 yrs after tv bought. TV only 3-4 yrs old. Thanks for any help.


This blue is caused by magnetic fields. Either the speakers of tv is faulty or demagnatziser not working. Switch of tv and remove powercord from wallsockets. Leave for about 10 hours and plug in powercord and switch on. if demagnatiszr is working the blue will be gone. if not have youre tv demagnetized

If hometheatre or radio speakers are closer than ½ meter this could also generate coulouration of screen. move speakers further away. If tv is on and and being moved your static electricity can also cause this. So switch of if if you move your tv.

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.

Blue spot


the model number KP-51WS510 deosnt use a bulb or lamp. and touching the face of the lamp will not cause color problems in the picture. if your tv is an LCD projection then i would suspect the optical engine as the culprit. to check when you turn the tv off do you still see the blue distortion? if so then you have a bad optical engine.......as long as it is an LCD projection.
