Re: Internal Cleaning Of MM52110
Really it all depends on how handy you are. Yes thes sets do have three lenses and a couple of mirrors that should be cleaned every year or two, and a few tweeks on the screens and focus controls. In my opinion, this should be done by someone who knows what they are doing. A TV set is not a place to be experimenting around inside of.

Being able to read a schematic and understanding how a TV works are two different things. These chassis that RCA used in these sets can be somewhat complex to troubleshoot. I would geuess that unless the power light comes on at all then you have a dead power supply in the TV.
