My kp 53s65 picture seems to be darker now than

KP53S65 is a rear projection Sony several years old--It is not a DLP and does not have a bulb--it has three picture tubes---if the set has not been serviced in a long time here is what you can do to try to improve it:

1.) Unplug set
2.) Remove back cover
3.) You will see 3 black lens (one for each tube)
4.) With a paper towel (spray glass cleaner on it) clean the dust from the three lens---if they have not been cleaned in a long time and have dust on them the picture will be darker and less distinct.

5.) Replace back cover and plug set in to see if this has helped----I have seen some where there was so much dust on the lens that it looked 50% better after just cleaning the lens--depending on area you live in--should be cleaned once a year.

I do this here for free so if this has helped you please take a minute to give me a vote here.
