Question about RCA R56WH76 Projection Television
When you say it is dark do you mean no contrast or some channels are dark while others aren't. While cleaning would certainly not be a bad thing you may also need to increase the crt drives if the unit is several years old. This is normal but unless you are familiar with the unit you could do more harm than good. Cleaning the lenses would be an easy first step. Unplug the unit from the mains. Remove the rear cover. You should be able to see the three lenses. Using a clean soft cloth spay a small amount of general purpose cleaner such as windex on the cloth. Using a circular motion clean each lense being careful not to move any of the focus adjustments on the lense assembly. When you have all three lenses clean reassemble unit and test. If this was your only problem you should have a better picture. If the unit is still too dark you should have a local technician adjust the crt drives. Good luck and be careful!
