Dlp tv color goes fuzzy and green


Its probably unrelated to lamp, take the lamp out, try it again and look into the lens, if its still very green the projectors electronics are failing. The projector generates pictures as 3 streams of info Red Green and Blue. It looks like the projectors red and blue electronics are failing, but the green is working.

Fuzzy Picture


Fuzzy is a funny word. I never use it to describe a picture problem. That because fuzzy can go too many different ways. There is snowy fuzzy, blurry fuzzy, grainy fuzzy, and demodulated fuzzy. If the set goes out of focus intermittently that has something to do with the focus ciruitry. If it goes grainy that is a front end problem, usually tuner related. The other types of fuzzy are generally associated with problems in video processing some where. So, which is it?

Oh, and BTW that unit has three small picture tubes in it, one red, one blue, and one green. It doesn't have a 'bulb'.

I have a Panasonic model # PT-44LCX65 TV and have just replaced the lamp, as it was time to do so. A pink dot, that appeared before the old lamp needed replaced, remains on the picture. How is this fixed?


There are a few other threads on this board with the same issue, some say green spots, some say red spots, in my case it was blue/purple spots, but the solution is the same for all of them. Contact Panasonic and tell them that you read online that they are offering a warranty repair for this known "fuzzy spots" issue. They will send out a local repairman who will perform an EEPROM update to one of the computer chips inside of your TV, and viola good as new.
That is what others on this site suggested to me, and I did it and got all repairs covered under warranty by Panasonic even though my TV is 2+ out of the warranty period.
Good luck!
