Mitsubishi dlp tv picture is getting darker
One of two possible issues:1. Lamp is nearing end of life and may dim just before total failure.2. A few of these models have 2 mirrors(check with Mitsubishi to see if yours is one) A large mirror in back (never gives a problem and do not try to clean it. Some idiot in these sets used a small mirror inside that the optical unit shines the picture into (wedge shaped mirror and small) and it is facing up----the fans intake air from the front of the set around this mirror--it gets coated with lots of dust---Picture can loose up to 70% of its brightness and clarity if that mirror is dirty--looks like 20 year old set .If you do not wish to check with Mitsubishi GOOGLE THE MODEL NUMBER with "mirrors" to see.If it has 2 mirrors I can tell you exactly how to get at it.SD TECH
How to clean mirror and optics mitsubishi 73 dlp
You have to remove the lower panel on the back of your tv, then remove the light engine. Unhook the wires attached to the DMD board. Remove the DMD board. Remove the heat cink from the DMD board. remove the optical lens but don't touch the lens. There is a video on shopjimmy.com that shows the entire procedure. Takes 2 hours. The optical lens can be cleaned with an eyeglass cloth, same for the DLP chip lens. no wet solutions on lenses. Remove dust from other internal parts with compressed air in a can. Your picture will be clean and clear. Wear latex gloves and make sure you are grounded to prevent static electricity.

Hi
Have you tuned the channel frequency tuner? Use the remote to bring up setup menu on TV, scan channel frequencies & save. If it's an old TV that can't pick up digital signals, then you need to get a digital set top box & tune to TV.
