Little Square color blotches


The most common reason for this is your video card overheating. You did not post the make & model of your computer, but if you have a separate video card installed check it for overheating. Pull the side panel off the computer to inspect. If your card has a cooling fan make sure it is still working (it may have failed) and not clogged with dust. If you have integrated video (the video "card" is part of the motherboard, not separate) check for dust & clogging in the vents. This is especially important if you have overclocked the GPU (video card processor) or the CPU, many gamers do this.
If you are still having problems, I hang out at www.suggest-a-fix.com, a free help forum. Post in there and we can go deeper. This forum is just not set up for in-depth communication.

KF-50WE610 blotch of color on screen


Either dust/dirt inside (unlikely but possible) or a damaged optical light engine--Google the model number with "problems" etc.

Rca scenium 50 inch dlp. i now have 3 black blotches in the screen. they look like giant finger print smudges. very noticable on light colored screen.


You have a problem in the light engine portion of the set. Somewhere in the optics. It could also be a build up of dust or a foreign substance. Have a repair shop give it a good cleaning inside. You may want to pull the bulb and make sure there is no foggy places inside of it. Thanks

Yellow ring on screen of KDF-E50A10 Sony Wega


The optical engine has a build up of dust. This can cause yellow shapes and blotches to appear. It is no easy task on this model to dismantle and clean the engine.

Paper jams w/ all types of paper, Ink blotches...


If you're getting spots on the prints, run the Remove Ink Smears routine in the maintenance. It will clear the ink from the preheater. User packing tape to pull dust off of pick rollers. It's easy to unclip the unit and roll it on a piece of tape to remove dust.

Dark Blotches


This is probably caused by dust, either on the mirror, lens, or possibly inside the light engine. There is a 5" dia hole on the side of the back of the tv where you can take out one screw and take the door off. this is just big enough for you to put your hand through to clean the mirror and lens. Hope this helps.

Dark blotches / Dirty behind screen


it could be dust in the mirror or in the optics,in this set if im not mistaken you have acces to the mirror from the back, anywhere from 12-20 screws it sould be easy to remove plastic cover first and the the mirror.this mirror are very delicate you dont want to leave fingr prints on it it will show just like the dust is showing right know. taking the mirror off will also give acces to the lense.
use someting soft to clean it.

Purple blotches


Ok, so I'm about to flip a lid with my TV. I am showing purple quater sized blotches all over my screen. I bought it for a discounted price because of this issue, in hopes i could fix it. I took the back panel off the TV. ( about a 6in * 6 in plate) removed the light bulb and cleaned the bulb and lens, where the light bulb faced. I used a dust cleaner and special cloth. NOTHING! I took the entire front screen off cleaned it and then cleaned the mirror and second lens.... NOTHING! Then i heard that dusk sometimes gathers behind the lens and that should be cleaned. Try this, Its 4 screws, just be careful and remember the way you took it out, because it has to be replaced the same way.
