    The reset button didn't work and holding the menu button to unlock the keyboard didn't work. Is there a part I can replace to resolve this issue?

    touchy issue as if remote numbers would work you could go into hidden menu and do a hard reset of entire set--at this point since you did the repair I would double check the keyboard etc are plugged back and no plugs are off or loose from the DM--that keyboard release should work but if keyboard issue...

Let me know as I can look for this---the set has a keyboard lockout that is cleared by holding the menu or another front button for more than 5-10 seconds with set on---I can find the service manual and check if needed.

SOURCE: PROBLEM WITH MITSUBISHI WS 55411

I had the same problem with my model as well. Luckily, I had the extended warranty and a technician came out and said that many people with TVs of this model have the same problem. He replaced the main system board and the problem was fixed. It has been about 4 months now and the problem just came back again. My TV is out of warranty now, but I hope I can get a warranty on that newly replaced party which appears to have gone bad again.

Your model will have two picos mounted on the same board with the 7 capacitors they will look like resistors without the color bands they will be F9B01 and F9B00 check them for continuity.

SOURCE: Mitsubishi WS-55511 Problem TV out - Getting only continously blinking green light on the front-panel

I had the same problem with the blinking light on the front of the TV and it would not power up. I read all the problems everyone was having and thought I was going to face a huge repair bill. The service guy came out, pulled off the front panel where the speakers are and disconnected the circuit for the front display panel. 3 1/2 minutes in my house, $90 service call. Apparently, when you give the TV too many commands at once, it's safety feature is to"shut down and lock up". He mentioned also that sometimes when these sets get to be about 4-5 years old, the wires in front can "leak" causing a shortage and then locking up the TV. I keep the circuit unplugged and operate the TV solely by the remote. Give it a try, what can it hurt!! Hope this helps.

Ws 73909 has bad dm module. Where can I get it repaired or replaced?


If this is for the green blinking light issue, you can easily fix yourself if you have a soldering iron. It is just a few capacitors. But if you can't, then just about any mom n pop service compony will fix it for you, but will charge a lot of money to do it.

Won't turn on.


Hi, If when you turn on your TV all you get is a blinking green light, you can find a lot of posts about this problem.  It usually is caused by bad capacitors in the DM board.  If you are handy and not afraid of pulling the DM board desoldering old capacitors and resoldering in new capacitors, this could be done for around $20 - $30.  You can look up Mitsubishi blinking green light or follow this link which gives a good discription of the process.

Green light flikering


Replace all 7 capacitors in the DM Module on the DM Power Supply Board. If it is similar to the WS-65869 and WS-65513 it will have a metal enclosed DM Module at far left of chassis, looking from rear. About 4 or 5 connectors, screws, and Module slides out. Take top shield off. Take good notes or use digital camera or video recorder to make re-assembly easy. These capacitors are 1000uf@16 volts. They always check good, just replace them! After re-assembly plug AC in and wait 90 seconds or more (green Timer LED will stop blinking), then press Power button. If Timer LED doesn't stop, look for small pinhole (System Reset) and press switch with pen or small screwdriver, then wait for green LED to stop blinking. Then Power On TV.
