How to Clean the Lens and Mirrors of Your Projection TV

How to Clean the Lens and Mirrors of Your Projection TV. Over time, you may find that the picture of your projection TV gets blurry or fuzzy. One of the first lines of defense in avoiding this is to clean the lens and mirrors of your projection TV. You can do it on your own with great care.

Step

Unplug the TV from the power supply. Never undertake any type of repairs on electric equipment without first disconnecting from power. Take care in handling any electric parts, as some may contain a residual charge that can shock you.

Step

Remove screws from the back cover and connection area of the TV. Be sure to put them in a safe place, or on a piece of paper with notations for where each one fits in the television.

Step

Gently remove the back cover. Locate the mirror and three projection "guns," as these are what you want to clean eventually.

Step

Use a camera lens cleaning cloth (or other very soft and gentle cloth) to clean the mirror and lens. Gently remove any other dust before closing the TV.

Step

Replace the back cover and screws. Plug back in the power supply.

Step

Turn on the television. Check to see that everything works correctly and that your picture is now clearer.
