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!

Why can i hardly see the picture on my rca 52wh74 its so dark

If you had the tv 4 long, it may need a new bulp.
meanwhile, I would clean the optics and such.
those tv`s usually have several fans inside and turn into
expensive air cleaners.

My rca scenium hd50lpw175 has a dark image, everything else works, no lights blink, no strange noises, just a dark image. Is it just the lamp that needs to be replaced?

Yup. What happens is, from the heat of the lamp, it begins to warp and gradually sag in the socket. As such, the light no longer gets projected onto the screen as it should.
It will likely die within a week or so, altogether. You will indeed need a new lamp. Make sure the TV is not knocked while in operation - that can cause your lamp to quite literally break (in two!) on the spot.
Learned that the hard way with my projector, which is built around the same principles as a projection TV.

I have an RCA 52in Rear Projection TV. One day it

There is a sub-board in this set that powers the convergence circuit. Often a big Ic shorts, two diodes and finally the main fuse. not something you can fix yourself.

Panasonic pt 52lcx66 won't turn on

Sounds like the light engine. Is this a DLP or LCD rear projection? Did you see any patches of color any time before the problem with the really dark screen. Please rate my answer and let me know what other questions, Tech Malick
