SOURCE: Mitsubishi ws-55513 green flashing light issue

I would asssume that the four cap replacement you're referring too is in the power supply of the DM module. (The large silver looking box on the left looking at the back of the TV)..
You can unplug that module from the signal board and remove it. Open the cover and you should find 4 16v caps in the power supply. If they look buldged chances are they are the failure. If not you might want to take an ESR meter to them to confirm they're okay and move on... In the back of that module is a small vertical board called the E2P module. Unplug it from the DM and plug the DM back into the signal board. If it powers up your picture might not be in the best alignment but you've identified the problem - just replace the E2P module.
If none of this works you're going to start getting into some greater technical requirements - but let's cover that when you get that far...

I purchased my WD 62725 in January of 2005 and have had way too many problems with something costing this much.  My green reset button is now blinking and I have read and tried all of the suggested solutions. All of them have failed.  I sure think Mitsubishi should be held more responsible than they seem to be.  Some one suggested a class action lawsuit.  I would sure join one.  Jack P

Don't think dm board will solve your issue, might want to check power board for buldging caps.

OSRAM VS. PHILLIPS
This is about buying replacement bulbs for the WD62327 TVs.I dont know about the other models but I purchased a PHILLIPS replacement bulb and it worked for about a week and then those dumb flashing lights and no TV. I did some research and others were saying that you had to replace some condensers. Shop would do it for 600 dollars..Well i sent the bulb back and bought an OSRAM replaement bulb. The TV is now working perfect.

Mitsubishi LT-46164 Blue Scree for all inputs. Can this be resolved with Firmware update? If so, how do I install with a flashdrive less than 4g?

A firmware update is not likely to resolve the problem - you are just missing HDMI input functionality.

But it won't hurt to get the latest firmware if you can.

Green Blinking light on Mitsubishi Unisen lt 40164, tv wont turn on?


Hi Since that did not work, The next thing is you have to take the back off the TV and find the main power board. On that board there will be some bad capacitors. Look for bulged or leaking CAP(s).
Replace them with same capacitors types. If you're not tech. savy Go to TV repairman. Good luck.

Hello, I have a Mitsubishi LT-46151. When I power the TV ON I'm getting a blue screen and the GREEN power light is flashing. The blue screen continues to show and then the GREEN flashing power light


Hey it sounds like u have did everything, so check and make sure u downloaded the right firmware on a good USB drive such as a 4GB and make sure format it with Fat32 before u download. Have seen that before with jump drive device and follow directions from Mfg website. If does not work then the CPU or Eprom has been corrupted and main board needs replacing.

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.
