That model has some bad capacitors that will cause this. Does the power light constantly blink when it wont start? If so change the (4) 1000uf capacitors on the DM board this should solve the problem

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.

I had to turn the main breaker to my house off to do some repair. When I turned the breaker on, the power light was blinking like it normally does. However, I have not been able to power on the TV. What is...


You are the victim of 4 leaky capacitors on the DM assembly, that's the vertical board all the way to the left looking from the rear of the unit. Replacement of the 4 capacitors (1000mf @ 25v, 105 degree) will restore the TV. As always, at plug-in the TV will blink for up to 70 seconds during the boot-up sequence so make sure to allow for this time. Good luck!
