This is called the blinking green light of death-----only one of two things can cause this problem.
First: remove front speaker grill (IT PULLS OFF) AND remove inspection plate behind it; look for the two bundles of wires coming down and to the right from the front keyboard of the set.
Unplug both plugs you find (different and marked so you cannot mix them up-----the idea is to take the front keyboard out of circuit-----set will still function with remote as receiver is behind front screen)
Try (after 70 seconds) to turn on with remote
If it comes on---defective reset button on front keyboard----use set only with remote or remove and remove actual reset switch---it is located behind and part of frame for screen----entire front screen would have to be removed to get at it.
Second: if disconnection of the front keyboard does not help, the DM unit is bad.
As you look from back of set it is large metal box at extreme left side.
The blinking light is the unit trying to "Boot" up-----these have a problem where caps and a few other parts in that unit fail-----kits on the net are available----Mitsubishi no longer sells or services these units but PTS Electronics does repair them.
Let me know if you have questions and try disconnection of the front keyboard FIRST.
REGARDS, SD TECH
darn, the simple fix did not work. i am moderately capable with soldering iron and a schematic, can you direct me to a repair kit with suitable instructions? about how much might someone like PTS Electronics charge if i shipped them the DM. Thx
Pts gets around 200 last time I looked;
try this link and note kit is based on ACTUAL model number

You will have to get the unit out of the set---large circuit board is inside.
I bought the recommended repair kit and replaced the large capacitors as instructed. The TV now powers up and the 3 projector bulbs go on, but the TV shuts down within 1-2 minutes.....whassup?
Either something happened when you took set apart etc or another problem--these sets have a self check----unplug set for a minute; plug back in and wait at least 70 seconds for it to boot up: when it shuts off and power light goes off:
Press and hold both the menu and input (device) buttons on the front of the set for at least 5 seconds and then release both.
power light should blink a 2 digit error code, pause and repeat it several times; 1,2 is no error found, 2,2 is short protect etc.
let me know what error code you find-----most of the time (my 30 + years) when you have a new problem after you did something----you caused a new problem---ie a plug loose etc.
