Projection TV is Dimming...Getting darker with every hour its on
I have a Panasonic projection TV PT-56HX40, I have had it for 6 years now, I allways knew that at some point I would have to get a replacement bulb/lamp for it. It started to dim about 3 days ago. With every hour that it is on it dims considerably more. I called a TV parts place and they tell me that my TV is not a Lamp TV but a 4 color bulb tv. My questions is: Could there be something elso wrong with my tv than the bulbs? If it where "a" bulb I would surely get a clear image from the other colors, right? If anybody has an insight to this problem, I woul apreciate it.

this set is over 11 years old now. All RPTVs have three CRTs light guns that create's massive static electricity. if this sets lenses and mirror have never been cleaned, this is why its getting darker. there is probably a massive build up of dust/dirt and grime on the light guns and mirror. clean these and it will perform like new again.

We replaced the lamp on our pr61lcx65 rear projector panasonic tv. We still have colorful spots and now it is getting darker and have yellow on bright picture and red on dark picture running through it. Please help.
====Disclaimer==== WARNING! There are high voltages inside the set even when unplugged dueto stored energy in some components. Do not attempt this yourselfunless you are experienced with this type of circuitry. I stronglysuggest that you get a professional repair person to do this work. ================
