How do i clean my screen

  CRT Rear-Projection - Before you can begin cleaning, you need to determine if you do, or do not have a screen shield. A screen shield is a hard plastic cover over the front of the TV screen. If you can't tell, give the front of the TV a light tap. Another way to tell is to check for ridges in the screen area. If you can feel ridges on the screen, then you do not have a screen shield. Rear projection TVs without a screen shield require a special kind of cleaner and rag. These are available for purchase at your local TV service center. Those that do have a screen shield should be cleaned with a dry or damp soft cloth. If it's extremely dirty, a mild soap may be used. Do not use paper products, such as paper towels, to clean the screen shield. Paper products can easily scratch the surface of the shield. Screen shields can have a tendency to streak while cleaning. If this happens, use a dry cloth and buff the screen in a small circular motions.

Where can I get screws for the back of my rca 52 inch tv? without the scres i can lift the back out for the picture to show.

It is easy. Take the bottom off. It is all one piece and just pops off. This is the part with the speaker covers. After you pop that off you will see 4 screws along the bottom of the screen. Take them out and grab the screen and pull out and up at the same time. It will come right off and it is not very heavy. Then you can clean those cobwebs out. I always take this time to feather dust the 3 projection lenses also for a clearer picture. Pop off bottom and 4 screws and it is wide open for cleaning.
