    are the colors (red, green, blue) mis-aligned? = convergence
    are they out of focus? = bad focus block or power/defection board

When you cleaned the "projectors: you knocked them out of alignment. If you cant correct by menu, I suggest you call a service technician, should be less than an hour for qualified tech to solve the problem, Good luck

It sounds like you have moved the mirror, turn it on and try to see if you can realign it. KEPP YOUR FACE OUT OF THE LIGHT PATH.

Picture looks 3d how do i fix


If you can access the three projector lenses you will probably find them covered in dust, this shifts the light slightly giving a blurry 3D effect on the screen. Clean the dust off with lens tissue and window cleaner or a cleaner made for glasses and this will restore your picture.

Picture is dark, appears to need either cleaning, some sort of adjustment or both.


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.

Blurry picture


You need to clean the projector lens on the optical engine using a soft cotton or, better yet, a chamois cloth. Also clean the mirror mounted inside the rear cabinet and also the front and rear of the screen itself.
If picture is still blurred then your the optical engine is most probably defective.

How to take cover off


First, my disclaimer:

I have a much older projector, but the way they are constructed hasn't changed a lot to my knowledge.

An excess of dust can shorten the life of electronics, it's a given. But the majority of these sets are allowed to collect dust for many years of operation before any problem occurs.
I sense that you may instead be asking about cleaning the lenses and mirror. Actually, the mirror, since it faces somewhat at a downward angle in these sets tends to stay clean. the lenses however, face upwards, and do get quite dusty, causing a blurry picture, with ghostly images on the screen at their worst.
To clean the lenses on most RCA sets I've seen, the screen must be removed. Allow the set to cool and voltages to dissipate for 30 minutes before beginning this process. There should be a removable panel beneath the screen, usually retained by screws on the backside at each end. REmoving the panel will expose the screws that keep the screen in place at the bottom. With the screen removed, the lenses (there are three) will be quite obvious. I clean mine with typical glass cleaner and SOFT paper towels. PAY ATTENTION not to allow any liquid to drip into the projector below or you may disable the projector unit possibly causing damage that must be repaired. If you are successful at the lens cleaning you will have restored the picture quality to like new.

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!

Dust behind screen


2 ways. There are two access panels about mid screen on the sides of the cabinet. Or you can take all of the screws out and take the whole screen apart ,all the way down to the lens on the projector. It is up to you. If you are pretty mechanincally inclined then take the whole cabinet apart, as you will be able to clean more of the cabinet. Use a microfiber cloth to clean both the screen and the rear mirror. Hope this helps. I usually clean mine every three months or so.

The TV Picture


The most common reason I've found for picture deterioration with projection TVs is dust build-up on the mirror. Try popping off the trim around the screen and look of several screw and retaining clips and remove them. Now remove the screen - it's just a piece of plastic. Now the mirror should be in plain view. Simply clean it thoroughly with windex and newspaper (you can also clean the back of the projection screen since you have it out). Now replace the screen and see if the picture doesn't look much brighter and clearer. This should be done perhaps every six months as TV generate a lot of static which attracts dust like a magnet. If the picture is blurry after doing this, it's possible to adjust the projector beams (there are three) to better align with the position of the screen, however I'm willing to bet this won't be necessary after the cleaning procedure. It sounds complicated, but trust me, anyone can do this. If you cannot locate any retaining clips on the front, you may have to go in from the back, in which case you'll most likely have to complete remove the mirror to clean it. It's a little more involved than the frontal method, but equally effective. It's also possible that you have a bad projector. When you get the screen off, make sure that each one is lit (the red one always looks dimmer than the green/blue ones). If one is out, try tapping on it, it might just come back to life, you never know. If not, have it replaced (usually around a $200 fix). Hope this helps you, and good luck!
