How to know the problem when your dlp tv wd 57733 turns on and wont show anything then shuts off in 30 seconds

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.

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.

Did your replace lamp come on the screen or did you lose picture? Just because the LED indicator suggest replace lamp it doesn't mean it needs it. If your pix was dull or loss of brightness then replace it, if not then just reset your lamp timer, check your owners manual for instructions.

Hi, I'm not a service expert. I too own a WD-62528 DLP TV with exactly the same problem. Manufacture date Nov. 2005.

I have found in another forum (CNET) that this is a very well known problem. And that Mitsubishi (MDEA) is not taking responsibility for it. A group of people tried to make a Class Lawsuit but it was rejected. Also other people found that this TV actually does not display 1080i resolution, that is a separate problem from the lamp issue.

If you are able to solve this problem with the TV (blinking lights requesting a new lamp all the time and TV turning off by itself), please let me know. If you want a link to the other forum, let me know and I will send the link.

Also, please don't be discouraged from trying to find a solution. Keep trying.
