You have blown capacators in your DM board. Here is a video that I used that guides you step by step video instructions for repairing TV. Bought the capacators at Radio shack for appx. $2/each.

This could mean the DM (HD tuner) failed. In the future connect your TV to a good surge protector. The manufacturer's solution is to replace the module and swap the memory from the failed part to the new one. (Except for the memory it is just an unplug one and plug in the new one.)
If you are handy with a soldering iron, you may be able to fix this by opening the DM module and removing 8 capacitors (as I understand the board) and replacing them. All 8 are 1000uf 16v 105C Capacitors

I hope this helps.

ONLY 1 of 2 things can cause this problem----
First thing to do is remove front speaker grill--it should pull out and is secured with plastic pegs--behind it you will find an inspection plate---
Notice the one or two pairs of wires coming from the front keyboard of the set---remove the inspection plate and follow the wires to the right--you can unplug both plugs(most have two and they are marked with letters and different sizes so you cannot get them wrong)
The idea here is to remove the front keyboard with its reset button etc from the circuit---You will still be able to try to turn the set on with the remote---
These sets have a Receiver that is called a DM board--(large metal box to the left as you look from the back) and if the power goes out the green light will blink for about 70 seconds and then go out---it is the Receiver booting up. It is called the DM board.
If disconnecting the keyboard allows the set to turn on--you have a bad reset switch and two choices---either operate the set only with the remote or to remove the front screen and get at the reset switch (it is tiny) and remove and/or replace it.
If disconnecting the keyboard does not restore the set to operation---the receiver is bad---there are 4 or more caps and some pico fuses that can fail in that unit---Mitsubishi no longer sells or repairs these--if it is bad and not the caps there is a company you can send the unit to and have it repaired--if you need to know their name let me know---
You can call them and get a quote for repairing the receiver.
Let me know what more information you need--I am here to help.
If this told you something you did not know rate this solution as very helpful as I do this here for free.
