Mitsubishi has problems with the thermal sensor going bad. They extended the warranty for several sets. The sensor is right by the lamp. Call mitsubishi and insist they do something for you. If you keep playing your set, the bulb could also be at risk. I would think your set is covered being a 62" set. Good-luck and be sure to act ASAP.

It could be a bad lamp but I've run into many of these TVs with bad color wheel assemblies. Also, if you are getting a dialog box coming up with these words," airflow blocked, TV will shutdown ..." that's a defective thermal fuse.

This is a job for a mitsubishi authorized service center. A tech can disassemble the light engine and confirm that the wheel is the problem. If you're still in warranty, great. If you're only recently out of warranty, call mitsubishi for assistance. Remember that persistance pays off when dealing with large corporations. You very seldom get what you're looking for on the first call or from the first person you speak to.

Air flow vent is blocked, tv keeps shutting down, mitsubishi ws-55615, how to fix ?


Mitsubishi's product line includes a wide array of LCD, Flat Panel, and DLP televisions to suit your home entertainment needs. The electronics division has the distinction of inventing the first rear-projection television and selling the very first HDTV in America. Their 400,000 square foot manufacturing facility, located in Irvine, CA, boasts the ability to produce more than 1,000 projection TV's in one day. The company's oft-stated goal of unmatched excellence is driven by their mantra: "Technically, anything is possible." In June, 2008, Mitsubishi introduced a new premium flat panel TV with an integrated 16-speaker sound projector.
Warranty Information
There is in-home service on all big screen models, which have warranties of 30 days for screens and one year for parts and labor. The LCD televisions have a one year warranty on parts and one year on labor with carry-in service. For plasma sets, in-home service is available on all models. There is a one year warranty on parts and one year on labor. The faulty thermal sensor, mentioned in the commmon repairs section, is now covered by an extended 2 year warranty, as is the problem related to the optical engine.
Common Repairs
For the following models: WD-52631, WD-57731, WD-65731, WD-Y57, WD-Y65, WD-57732, WD-65732, WD-57831, WD-65831, the most common repair problem stems from television shutting off almost immediately after it has been turned on accompanied by the message, "TV will shut down in a few seconds. Please check if the air flow is blocked." According to the Mitsubishi website, this issue is caused by a loose connection as a result of a faulty thermal sensor. For models: WD-73727, WD-73827, WD-73927, WD-73732, WD-7383, the most encountered repair problem has been in relation to the optical engine. Another common situation consumers have encountered is failure of the TV to turn on along with unceasing flashing of the green power light. The solution for this problem, caused by the DM board, will vary by repairman. Consumers have also encountered issues with moving vertical or horizontal lines appearing on the screen which can either be due to problems with the capacitor, light engine, or formatter board.

sounds like the projector globe is gone. i think you will need to replace it. if you are lucky there should be a pannel on the side or rear of the tv that allows you to replace the globe. pricey though.

good luck
