Make sure you tested the pico fuses inside the unit with the caps==two or three of them.
Also from front of set behind speaker grill unplug both plugs that go up to front keyboard--set will still work with remote===if set functions now then the reset micro switch is bad/damaged.
I am assuming the television is not powering up and the only thing it is doing is showing the blinking green light.
Unplug TV from the wall and see if it will reset itself.
If unplugging doesn't fix the problem then you need to find out what is causing problem. First thing to check are the fuses. Second thing to check is looking for burnt resistors or bulging on top of capacitors. Something caused the TV to enter so called safe-mode.
TV's carry alot of voltage in them so BE CAREFUL and UNPLUG THE TV.
If you are handy with a soldering iron then you can save yourself alot of money. An average service call & repair is $300-$450.
Replace the Capacitors on the DM board. You can get the WS55859 DM repair kit which covers your model from www.tvrepairworld.com which has the caps and the CD with repair instructions
I found this answer and I believe it fits your problem perfectly.
Your TV has two microprocessors that depend on each other for communication. The problem is that a power glitch gets them out of sync. Try this:
1. Press the power button and wait for the blinking light to stop.
.
2. Press all the front panel buttons one at a time, except for the reset, and power button.
This will send a command to one processor and sets an interrupt.
3. Hit the power button, and the TV should power up.
4. Set the TV to low energy mode(see TV manual to find out how to do this. Doing this step will help prevent the problem from coming back. These instructions were taken from a Mitsubishi service manual.
Check for open pico fuse in power supply caused

They are little green soldered in fuses located on the center board (the one with the STK's on it) toward the rear of the set near the large transformer.
