How to Fix Projection TVs
Most decent televisions can last many years before they break down or before they need significant repairs. Some televisions can last as long as 20 years if they are properly cared for and regularly cleaned. However, no matter how great the brand or the make of the TV, problems are bound to arise. You can save yourself a lot of money and lengthen the lifetime of your television by learning some basic repairs to your projection TV.

1
Inspect your television to see whether you can find out what is wrong. Flip through the channels. Check whether the picture is fuzzy or whether the screen rolls up or down when you change the channel. Pay attention to the brightness of color and the quality of sound.
-
2
Turn the television on and check the coaxial cable connection. If the cable is loose from the TV or the cable outlet, your picture can look fuzzy or blurry. Twist and wiggle it to see whether that makes notable changes in the picture quality.

3
Turn your television off and unplug it. Wear rubber gloves while you work because the TV might still be holding an electrical charge. Unplug any other hardware such as DVD players, VCRs and cable boxes from the TV before you take off the protective case.
-
4
Place the television face down on the floor and remove the protective backing. Gently remove the casing and set it down beside the television.
-
5
Examine the inner parts of the television. Look for dirt, grime, dust and other types of buildup that might affect the color and picture quality.
-
6
Spray air from a can on some of the dusty parts. Do this gently to avoid damaging your TV.
-
7
Use a soft cloth and gently wipe away grime and dirt from the picture tube and other parts of the television.
-
8
Replace the protective case, plug the TV back in and turn it on. Your picture should be bright and crisp.
-
9
Remove objects around the television that might cause it to overheat. If your television turns itself off during use, it is probably overheated.
