I have a RCA projection tv. While cleaning the mirror inside the tv, I
looked into the projectors and noticed dead bugs underneath the lens's.
The lens's appear to be sealed. How would I go about cleaning, without
knocking something out of whack. The model states it to be P5273IWK

Some projection tvs have three picture tubes called CRT, this crt system requires a little manintenence every once in awhile, lens and mirror cleaning as well as projection screen cleaning, there are other procedures that have to be ran sometimes to return the picture to a regular viewable level. With the projector type of TV, there is usually the light box , mirror and screen maintenence, these procedures should be done at least once a year and only requires a minimum of materials and time, and there are other parts and procedures that can bring the picture to normal viewing levels.
Check for dust on the lens. There may also be dust inside the projector on the mirrors, lenses, or LCD. If cleaning the lens on the outside doesn't resolve your problem, I would contact a professional to get the insides cleaned out.
you need to take the screws out from around the screen in the back, on edges, go to the front and take the screws out from the bottom of the screen, should be 4 or 6 in the front, pick up on the screen and lift off, only about 8 pounds, now clean the little mirror in front of the projector, and clean the dust off the projector lence, that will solve it, iv had to do this on about 50 of thease tv's
The yellow you see is all dust on the mirrrors inside your projector.
If u are lucky you can get the mirrors cleaned by a pro, if you are unlycky as i was, the blue mirror has burn and u need to replace it.
Take your projector to someone who repaire tv:s ot other electronics, they will help you. If its only the cleaning its cheap, if you need to replace a mirror its expensive.
I solved the problem by connecting a VCR to the TV and surfed the tv channels with the vcr remote, some how the new video input cables and the vcr solved this problem for me. I just set the tv on Video Input 1 and use the VCR. It wasn't as hard as I thought the problem was, just poor signal.
There is black insulating foam that surrounds the projector and it may be displaced to one side.This leaves about an 1 inch opening around the projector lens and that could be the source of the problem,dust being blown into the compartment with the mirrors. Cleaned the mirrors really well and used double stick tape to reattach the foam to the plastic frame and this will closed off the opening that maybe letting the dust into the mirrored area of the TV.
