It sounds like a lamp. What model do you have?

Depends if you bought a French OEM bulb or an aftermarket.jlittrell said:Jim,
I have the WD-62725 and ours is doing the same thing. Keeps turning off and sometimes will turn on with no picture only sound. Mitsubishi had replaced the lamp previously and I have made the comment to my wife it seems like the picture is getting darker. Do the lamps go out more often the older the tv gets?

French bulbs rarely ever dim more than 10% before they implode at 2500-3500 hours.
Mitsubishi TV shut down cause: "TV will shut down in a few seconds. Please check if the air flow is blocked" Folks, this happened to my TV, except it would do it once in a blue moon when the tv was new, so no worries, then as I replaced the lamp over the next few years it started happening more and more, so I did the research and found out that it was a known problem in with Mitsubishi extended the warranty on for an extra year (3 years). This didn't help me as my TV turned 7 years old by the time I got fed up with the problem. In a 2007 Mitsubishi Service Tip: VS-72C the problem is identified. All authorized tv repair shops should know about it, and if they don't tell them about this service tip. CURE: Replace the Lamp Thermal Sensor, located on the Lamp Cartridge Housing, with the new version, p/n 299P313010A, which is the new and improved connection. This is a simple fix, and should cost you about $80 for the service call and $40 for the part. I did this a few weeks ago Feb. 2013. Google part number: 299P313010A for a list of retailers selling the part. For about $120 you can get your TV back, or better yet, buy one really cheap and fix it for $120! A 65 inch DLP is an awesome TV with awesome picture quality. Well worth the repair!
