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.

Do you have your TV plugged directly into the wall? You cannot plug into a power strip, it needs its own direct power source. Also, I have heard that there can be electrical problems inside. I have this same model, I love it, picture and sound. I just replaced the bulb for the first time last night. It was a little premature to replace it now but I know what caused it. I bought a new bulb and it works like a gem. If you ever need to change the bulb do it yourself. It takes maybe 2 minutes. The bulb looks like the Flux Copassitor and all you do is remove the door in the back on the side. Unscrew the the 2 screws that hold the bulb in and just pull out. When you put the new one in make sure you do NOT touch the glass on the new lamp. Just slid it in and screw the 2 screws back in and make sure the door is closed and tight. My uncle had a service guy do his and he got raked for 5-$600, The bulb costs about $200. Should last about 5-6 years at a rate of 5-6 hours of TV on time. Hope this helped. If not, sorry, but at least you know how to change the bulb. Good Luck!!!

I think you answered your own question. You have a rear projection television. It sounds like the lamp is not functioning correctly.
All projection lamps have a recommended life measured in hours. I checked the web and this model appears to be about 3 or 4 years old. from 2005 or so.
The lamp in my Samsung is rated at 3000 to 5000 hours, I had 12,800 when the service Tech was in changing another part.
3 or 4 years running one lamp is a good run. This is why DLP has lost favor for table top sets, Most are LCD or Plasma now.
Check you TV for it's lamp model and them shop around allot. Lamps are not cheap however some suppliers offer much better pricing that others. Care should be taken to make sure you order and purchase real replacement lamp and not a clone / compatible model. Original parts should produce the picture you are expecting

Most likely a bad Polarizer within the light engine of which you cannot buy. The entire light engine would have to be re-built or replaced and they usually start around $600.00....
