    Same model with the same problem. Any answers yet? Thanks

    We have a WD-57732 and have the same exact problem with the same error message.  The airflow has NEVER been blocked.  It doesn't matter whether the house temperature is low in the winter or in the high 70's in the summer or in winter heating mode.  We thought we figured out that it shut down on start-up after not being used for a long period, but we have found that is not the case.

Go to mitsubishi-tc.com. then go under warranty, they have a recall on the thermal sensor and will replace it for free.

Mitsubishi 73" DLP powers on, through welcome
If you are getting at turn on source and back ground is all blue the set will shut down rather quickly;

I have a suggestion, if it works fine, and if not it will not hurt anything.

with original Mitsubishi remote turn set on and then Menu, 1,2,3, enter.

This is the soft reset that most of these sets have (cannot be sure since Model number above is correct?)

The reset button on the front (if it has it) just shuts the set down and reboots the DM unit inside.

Most of these sets when it is pressed the green light will blink for about 70 seconds and go out; that is the DM unit rebooting and the soft restart is something else.

Let me know what you find before you rate this information.

My tv keeps shutting down when I turn on. The message on the the TV screen said that "the TV will be shutting down in a few minutes". I resit the lamp in the back of the TV and the TV works after I reset...
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.

Have a Mitsubishi 52725 52" DLP The TV shuts off frequently. It tells you "the TV with shut off in 30 seconds". It seems warm but I have a fan in the rear to cool it down but sometimes it still...
does it give you the "airflow" message?
if so it needs a new thermal sensor by the lamp, known issue defective sensor..

if not, suspect bad capacitors
there are many bad caps across 3 board , all part of the chassis.
a repair center will ship the chassis into mits for rebuild, about 400 or 500 total bill

Error Message
If the set is only 3 1/2 months old, you should still have warranty coverage. Opening up the unit will void the warranty, so don't open up the set. Call for warranty service. In all probability, the air flow sensor is defective. The message you are seeing is a result of the air flow not being detected or not sufficient. In any case, this is a covered problem and should cost you nothing to fix.

Shut Down Message
The repair is to have the DLP engine replaced!!
FYI: The engine also can cause the set to shut down without any display or might even tell you the lamp door is open when it is not.
