I have a sony KDS-R60XBR1. The lamp burned out so I ordered a new one. When I took the old one out, I noticed the area directly in front of the lamp, the first thing the lamp shines into, is a little dirty...


Use a eyeglass cloth or LCD screen cloth. Use NO solvants on it. Just dry cloth. ALSO goto the settings menu and put the tv in HIGH altitude mode. There tv's get too hot and the light engines go out. Green or blue tint. or dots. It also helps the lamp last longer.

Mitsu 65" DLP-picture seems washed out


Most likely cause of your trouble is dust on the small mirror inside you set. Your DLP set has 2 mirrors not including the DLP chip itself which has about 500,000 tiny mirrors. The 2 mirrors reflect the DLP chip image to the screen you view. The first is the main suspect it's about 4inches by 7inches. It's mounted on the bottom center facing backwards. This mirror faces slightly up and somtimes after time dust, smoke, dirt settles on it . The second fills the space of the entire back of the cabinet but it faces down and takes alot longer to get dirty.
The compartment is sealed but dust seems to find it's way in. If you remove the screws that secure the screen assembly from the top , sides and bottom. Make sure to have a friend available the screen assembly is delicate when it's not mounted to the cabinet. You can remove and clean the mirrors. These mirrors are glass and you can use glass cleaned. Don't use glass cleaner on the screen it's plastic. You can clean it if necessary with plastic cleaner only. Probably not needed.
Good luck.

Sony KDSR50XBR1 50 black screen, no faults! Lamp working, fans OK Sony KDSR50XBR1 50" HDTV: The light engine was working fine before the fan quit starting on it's own. After disassembly, cleaning and lubrication of the fan, I have no errors but the input display or menu options will not post on the screen. The lamp is on but seems to either be projecting a solid black picture, or not be at full brightness and there are no faults. I have a solid greed LED on top, but can get no picture. Sound is fine. What should the lamp voltage be at operating mode? I have tried reseating connectors and pushing on the wires to make sure the connectors seat. This is baffelling because the lamp fired fine for 1 second before the stuck fan issue was corrected and I have no faults now after lubricating the fan. I'm going to check connectors again today as a triple check; as I did remove the power supply. The TV has been reset per instructions in the book. Any advice would be much appreciated but I cannot believe it's the OB as it worked fine before the fan quit and it's about 14 months old. I'm thinking something may not be assembeled correctly, but everthing seems to be pretty idiot proof for re-assembly. Also the menu or input banners will not post. I have 2 new lamps, so it's not that.It seems to be stuck in somne black screen mode. The large fan does start by itself now after cleaning and lubrication, therefore no fault blinks. Please help!!!
