I have a mitsubishi ws-73711. I get a rapid flashing green light after unplugging and plugging back in. TV won't power up. I replaced the seven DM capacitors and the exact same thing is occuring. I am getting an error code of "1" "2" when pushing the device + menu buttons. Is there something else to try?

the green light blinking is normal if set has been unplugged--when set is plugged back it should blink for about 70 seconds and then go out--then you can try to turn it on---it is the DM unit inside the set booting up.

If the light just blinks and never stops you have likely bad caps in the DM unit---there are kits available for that.

The other possible reason is that so called reset switch may be bad--fairly easy way to find that out and it is more common than you would think, let me know if you have questions.

Thats a very common problem caused by weak capacitors on the DM board. When power is lost the caps discharge and when the power is restored they cannot recharge so the timer led will blink non stop. You can get the DM repair kit for your model from www.tvrepairworld.com it contains the upgraded capacitors and the CD with repair instructions.

You need the WS55909 - WS73909 DM kit. You can get it at the following link which contains the capacitors and the CD with instructions on how to do the repair.

Replacing those capacitors usually solves the problem however sometimes the issue is back in the power supply. Make sure the 12 volts be supplied to the DM module is present. If not you'll need to fix the power supply.

The Bulb in the unit needs to be replaced. To confirm, look in the manual for the set and it will explain the flashing lights by the numer and duration of flashes. Hope this helps.

could be a lot of things really. when you replace the bulb, there is a switch that will prevent the tv from turning on if the cover isn't sitting correctly, by moving it that might have shifted so it would blink, but not turn on. if not, well get it serviced, sorry

Good Day, charliek1;
This a very common problem with model. Don't listen to other comments unless the use the correct replacement parts.

SYMPTOM: Power LED does not stop blinking after plug in.

CURE: replace C9B01, C9B02,C9B10, and C9B11 (1000 uFD 16V) on the DM PCB. Replace them with part # 181P734030 (680uFd 16V).

The DM Board (PCB) is located on the very left side of the TV looking from back. Caution on removing Board and note what cables you disconnect to access the Metal Shielded Board.
Good Luck, big IRISH.

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?

I have the same problem and I don't know what to do>

The four cap replacement in DM module repair is simplistic
and incomplete, as you found out. ALL defective DM modules
have bad SMC's ( small "top hat" caps) AKA surface-mount
capacitors that can be changed only by the most highly skilled
bench techs. We used to change out hundreds years ago in
camcorder circuit board repair.DM board repair is a much more
accessible,thus more "do-able". For more info.............T.
