Preparing for Cleaning
If you own an older style rear projection television, you will want to learn properly clean the set without causing damage to the different parts. Certain cleaning solutions can lead to problems like corroding and distorted picture. To prepare the rear projection television for cleaning, you will want to remove the back cover. You can unscrew the screws in the rear in order to do this. You will then have access to the mirrors and projection lamps. In some sets, you are able to remove the front screen as well in order to clean it.
Frequency of Cleanings
You should clean the lamps and mirror of your television annually or on an as needed basis. You will need to dust and clean the front screen much more often; most likely every couple of weeks or so.
Your Cleaning Solution
Use a cleaning solution that is safe to use on glass and will not damage the coating on any of the parts. Many times, a camera lens cleaner will work particularly well on the mirror and projection lamps. Avoid any cleaning products that contain ammonia since this can lead to corrosion. Apply the cleaner with a lint free cloth in one direction in order to avoid streaking. Once you are finished with the mirror and projection lamps, you can clean the front screen with the same cleaning solution. Also, if you have a plastic cover that protects the screen, you can use a dry cloth in order to dust this while cleaning the television. You can also dust off speaker grills with the same dry cloth.
Considerations
Remember to always disconnect the power before attempting to clean your rear projection television. You may also want to look through the television manual in order to review any specific cleaning instructions for that model. Don't move around any parts of the television set while cleaning. If you break or misadjust one of the parts, it can prove to be an expensive fix. Also, don't use paper products since they can easily scratch the screen.
