    TV Won't Power on Green Flashing Timer Light.

    I've reset, I've unplugged, I've unplugged and held the reset while plugging in. No luck. I'm going to start with the easy suggestions like blowing the dust off. Then I'll kick it. If that doesn't work, I guess it's time to shell out some coin for someone to come replace the DM. Let me know if someone figures something out other then the expensive DM replacement.

    I also won a WS-55859 that is having the same problem. Power went off today while at work and when we returned the famous blinking green lamp on the front panel. I have unpluged and pushed reset as manual states but nothing seems to work. Would really appreciate some cheap Help. Thanks

The green power light is continually flashing and the tv will not turn on. I hit the reset button and nothing happened. I have exhausted all other troubleshooting methods. Please help, what should I do?

99% of the time the dm is the problem. if your lucky its the power supply capacitors located on the power board. this board is contained within the digital module.the capacitors are
1000mf/16v. mitsu has changed these to 680mf/16volt. theses caps will not necessarily look bad and should be checked with a capacitor meter

Someone left a WS-55859 TV in front of the dumpster at work. Plugged it in and timer light was flashing green. Removed the capacitors on the DM board and tested all 7, four failed. Bought 4 new ones, same as original for $1.90 each. Installed them and tv is working great. Remember, after unplugging this tv & back in, when you power on, the timer light will flash green for up to 2 minutes then stop. This is the normal bootup process after unplugged from a wall outlet.

Here's a guy who fixed it himself, with no prior soldering experience, and completely documented the process.
check it out here:

The only thing I would add, based on all the online Q&A sites, which all agree that replacing the seven (7) Capacitors on the DM board is the recomended fix, is to upgrade the Capacitors to:

1000 micro Farads @ 25Volt 105 deg.Celcius

Hdtv flashing green light for timer tv wont turn on

If the TV is a few years old the flashing green light means the bulb need to be replaced. That's why the TV will not show a picture. Check your owners manual on how to replace.

My Mitsubishi Medallion tv stays on for about 10 minutes and then shuts down and won't turn back on until a period of time has passed. It is a rear projection tv about 9 years old. Can anyone help ex

When it shuts off and the green power light goes off, press both the menu and input buttons on the front of the set (not the remote) and hold both for about five seconds and release.

Power light will blink a two digit error code like 2 blinks and then 3 blinks and repeat it several times.

What is the error code?

The other night while watching the tv turned off by itself.

There are two usual causes for this. One is the convergence integrated circuits have failed. The second cause is slight leakage of one or more picture tubes.

Green light flashing

This is most commonly caused by the Formatter not booting up. The cure is to replace 4 capacitors on the Formatter board 1000 mfd @ 16vdc. The Formatter is the large stand up shielded board on the left as you look in from the back of the set. The capacitors will be domed on top if bad.
