SOURCE: mitsubishi wd-62825 dlp

The WD62825 has a Digital Module located on the left side of the chassis looking at it from the rear of the set. It's housed in a metal box that can slide out of its holder after removing the trim screws.
The module has its own power supply board and there are a group of 16v/1000uf caps on that board which commonly fail causing the constant flashing standby light. Further back on the module is a small board about the size of a matchbook called the E2P module. Its SMT (Surface Mount Technology) caps also commonly fail which can cause the same symptoms. Techs can tell whether the E2P has failed by simply removing it, hooking the DM back up and trying to power the set. If it powers on the picture won't be much good - but at least you can tell what's keeping it down...
Back to the caps on the pwr board. If they've failed they usually will buldge visibly on top. And ESR is almost not necessary. In any event that's the nuts and bolts on this model.
Is it a job for a layman? Yes and no - you might strongly consider a tech if you don't feel comfortable removing all the connections that the DM has with the signal board. There are about six - multi-pin - wired connections to unplug and then sliding the DM out of the unit and carefully removing the screws and latching to take the DM top cover off...
Hope this helps.
Bill

SOURCE: Mitsubishi WD-73732 TV

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.

Looses color after playing for short time. color comes back after turning off for awhile


First see if it does this with a DVD etc connected--rules some things in and out.

Most of these have two resets, the soft and the hard-----if it has the soft with the Mitsubishi remote: (set on) Menu, 1,2,3 enter.

I would not do the reset if no issue with a DVD etc.

My mitsubishi wd-65c8 has a flashing green light.. I have replaced the capacitors on the DM board and the same is happening.. what else could be the...


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.
