Contrary to popular belief, any display product can have "Image Retention" and even "Burn-In". This is true for Plasma, LCD, LCOS, DLP, and CRT. I do not see a model number provided, but I would bet that you have an LCD rear projection TV rather than a DLP projection TV. If this is the case, the Blueish and Greenish blotches you are seeing on the screen are the result of UV light damage. UV light will move heavily damage the Blue panel, due it's short wave length. So, bad Blue or Green (absence or Blue) is typically the the first visual indicator of a problem. Replacing the Light Engine will resolve the problem.

I have yellow and purple blotches on screen


I had this same problem on my Mitsubishi rear projection WD52527 model television. The optic engine was changed twice, and the blotches were still there. It turned out that it was the mirror inside the television that was causing the purple blotches. It was filthy and once the repairman took it out and cleaned it the discolorations were gone. Hope this helps

Dark Blotch on rear projection TV screen


usually these are caused by cleaning the screen with a damp cloth or fkuid rear projection tv's usually have two plastic screens separated by about quarter inch with bulbs between,one being a magnified screen.problem is,condensation can occur causing various blotches,letting the screens naturly dry out usually solves this but failing this you have to strip down and wipe them with clean dry cloth.be careful though the inside screen is very delicate.

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.

VT45 Projector: Blue pixels throughout screen


If the problem is what I describe as a blue haze over the entire image projected, I was told this is a defect in the cable - we have a Dell Video Projector 2300 - and it takes only a dell VGA cable.

So, the problem is in the cable - solution is replace cable.
