hint: the two pins the lamp plugs onto go directly to the ballast which is really a power supply for the lamp.

not clear from all you have said if ballast is the problem===these sets had a lot of issues; anything, even too much dust on the fans inside will shut it down...........

Won't power on

Have you checked the power cable or the back cover of your television? Often times, customers forget to plug their television in after a repair. The back cover for most DLP or LCD projection televisions have a sensor as well that will keep the television from turning on. If there is still no power after the steps below, you may have a problem with your power supply module.Consult your owner's manual or a service technician for assistance..
If the previous advice wasn't helpful, try this: Do you hear your ballast "click?" The ballast is what powers the lamp. Initially, UHP lamps need to be jump-started with a lot of energy. The ballast will make a clicking noise as it starts up the lamp. If there is no clicking noise, there may be no power to the ballast or the lamp.

Mitsubishi WD-57732 LAMP continuously burns out. I have replaced four in two years. We don't watch alot of TV.

There are a few issues here:

The lamp you are purchasing could not be OEM, or a compatible lamp--OR you have a ballast/power supply issue blowing the lamp out.

The original lamp is manufactured by Osram, but a better and compatible lamp would be Philips, who pioneered the lighting for DLPs. The ballast needs to be compatible with the lamp and Mitsubishi ballasts are compatible with most lamps, but work best with Philips and Osram. Only buy from an authorized dealer!

Need to replace ballast on mitsubishi wd-62526

there is a good chance that it is not the ballast.
you would need to measure the voltage on the heavy wires going to the ballast. to see if there is approx 300vdc on them if not or if it is low then the problem is in the chassis or the engine.

Hi there

The most common cause for a Ballast to go faulty is power failures & power spikes and off course lightning.

I normally advise my clients to hook up a UPS to the Projector just to make the power supplied to the Projector more even and smooth.

Ballast problems however occurs more than often on any model of Mitsubishi I have found.
