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

I am not laughing but I would suggest if possible from the rear with a light first to see if any of the bugs are on the mirror at the rear of the set inside or the lens This set should have inside---look for that first---anything on the mirror or between it and the screen will be magnified and projected into the picture----it is possible to take a good photo and post it here as well.
I have seen this once before---had lots of little moving specs on screen of a Sony---they had several hundred knats inside flying around that were attracted to the light and warmth there.
Solution in that case actually involved use of Moth balls for a while in the area.
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.
Hi, much easier to access the front screens (there are 2 sandwiched together) by removing the top back cover, be prepared for lots of screws and when you get down to the last 2-3 screws get some help, on the inside of the back cover is a large mirror, some are made of mylar, do NOT clean or even touch a mylar mirror, the others are made of real glass and the back will be much heavier than you think (and very expensive if you break it)once the back is removed you should have access to the bug, good luck, video-tek
I would recommend getting a service manual as the light engines are a little complicated to get out. where the manual would have an exploded diagram which would make it alot easier. If you need a link to get the manual let me know and I will post one for you.
it's fairly easy to remove the screws on the back bottom portion of any rear-projector television. when the bottom part is removed, you will see both the mirror and the 3 lens. isopropyl alcohol or windex should do an efficient job. a soft lens rag can be found at any camera store. i'd spray the lens rag instead of the actual lens or mirror when doing this job.
The important thing here is cleaning the refelective mirror inside you tv .We have noticed in dirty areas the dirt on mirror makes blurry picture.THerefore you have to open back cover and than tp cover to clean mirror and also dont forget to claen c.r.t lenses ,sisnce they are mounted facing upward ,lot of dust sit on c.r.t lens there fore clean 3 of them r.g.b..And you will notice on picture diffrence.
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.
