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.

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. Make sure all bad caps are changed.

The first would be excessive dust causing inadequate airflow through the lamp cage. Cleaning the filter may resolve the problem.

It could also be that one, or both, of the temperature sensors could be defective. This is a known problem to the extent that Mitsubishi extended the warranty an extra two years on your model and similar models with the same design.

Mitsubishi Digital Electronics America, Inc (MDEA) 2006 DLP® Projection Televisions Models: WD-52631, WD-57731, WD-65731, WD-Y57, WD-Y65, WD-57732, WD- 65732, WD-57831, WD-65831.
As part of our commitment to quality and customer satisfaction, MDEA is announcing an extension of the warranty coverage to replace the thermal sensor for the above referenced models. For a period of two additional years beyond the one year limited warranty, MDEA will cover the cost of the thermal sensor (parts and labor) at no charge. All other terms of the MDEA limited warranty will continue to apply.

Sound But No Picture Shuts it's self Off


Hello... About the only thing that can cause this symptom is a bad lamp. Most of the time, you can look at the lamp and tell if it's bad. If it's not shattered, it might have an odd bulge at the base of the reflector, or a gray circle on the clear tube at the bottom. I hope this helps!
