Clean rear projection TV?

by wern19 / September 29, 2005 1:09 AM PDT

I have an older model Hitachi rear projection tv. the quality of the picture leads me to believe it needs to be cleaned. does anyone have any experience in removing the back panel to clean the interior components (screen, lens, mirrors, etc.)? is it advisable for a non-professional to do this? any feedback will help. thanks.

Most big screen TV's...

You should be able to remove the back cover from the set. You may have to remove screws around the connection area too, as this will be connected to some sort of board inside. I would certainly caution you about power issues, make sure the set is unplugged. Once removed,in most big screens you will now be exposed to a mirror,(the mirror will often be attached to the back cover you removed) and you will see the 3 "guns" red/blue and green. If you are unsure of what to use to clean, go to any quality camera store, find out what they would recommend to clean expensive camera lenses with, this should be safe for the mirror and lenses inside the TV. Obviously you do not want to use anything that could be abrasive. Some sets, like Pioneer, you will want to enter from the front, by removing the screen, this will give you a chance to clean that too. For someone that is comfortable with what they are doing this should take about 1 hour. Good luck.

Don't use ammonia based cleaners

on any of the plastic components such as the screen. The ammonia can cause the plastic to cloud. Best not to use it on the lens or mirror either.

Keep in mind that just because the set is unplugged doesn't mean you can't get shocked. Certain parts of the chassis can carry a residual charge that will send you flying.

Don't move any part of the projector assembly.

If you see any leaking cooling gel around the projector tubes then get a technician.

good luck
