Re:
FIRST CHECK CONNECTOR "DR" FOR PROPER CONNECTION, BETWEEN THE DEFL MINI PCB AND THE MAIN PCB. 2. CHECK C5A09 AND C5A50 BOTH 33 UFD 50 V OFF OF IC5A01 ON PCB-DEFL MINI. 3. CHECK FOR LEAKY IC5A03 PART # 270P704010 ON PCB-DEFL MINI 4. SUSPECT THE HIGH VOLTAGE BLOCK PART # 920P016010 IF STILL NO HELP PROBLEM CAN BE INTERMITTENT (TEMPERATURE RELATED) CAUSED BY IC7D04 PART # 275P245010 ON THE DOUBLER PCB THIS WOULD BE A THIN VERTICAL LINE IN CENTER, IF GUNS WERE ON.

A full service manual is available online---I will presume you tried to unplug it for a while and then power back to see if will reset itself.
This set has three hidden menus---one is the OPTION menu--in that menu with the Mitsubishi remote you can do a hard reset of the entire set= sets all back to factory except convergence adjustments which are stored in another area--cures all kinds of oddball issues.
I can give you a link to the manual and the page numbers for the OPTION menu.
Note: the other two hidden menus are Convergence and adjustment--do not go into adjustment menu as one wrong move and poof!
Check Your Rear Projection Light Open Back Cover it a little Door on the back ov your TV Set Possibilty Light Burn Out ....Cause of this Problem Fan Malfunctioning Or The Bulb as to be change for new one ... Type The Brand and the Model ov your TV According To your Model it will gave you a list ov different Light Projector Make Shure You dont Touch the bulb with your bare Hand when you put it On Because those light produce very hi Temperature and cant burn out immediatly or explode.
When green light comes on and then goes off, ON the front of the set press and hold BOTH the Menu and Input buttons at the same time for at least 5 seconds and release both buttons.
Power light should blink a two digit error code; most common is: 2 blinks, 2 blinks, a pause and it will repeat the error for a total of five times.
Let me know what error you find and I will tell you what it means.
If this information told you something you did not know, rate this solution as very helpful as I do this here for free.
Look on the back of the set and confirm the correct model number--55805 does not show as a good model number.
If blue will not adjust what ever it uses (either one or two convergence chips need to BOTH be replaced and then the set adjusted.
I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR for most of these sets.
Double check the model number and let me know and I will tell you what parts it uses and also then be able depending on the model number to give you the instructions etc.

If the LED never stops blinking, you have a failure in the DM module. It is usually caused by 4 or 7 1000uf capacitors going bad inside the module. Mits says to replace with 680uf 16v caps to fix..
check this site first http://www.chrisandnat.com/Projects/BlinkingTV/blink.htm if you dont have this in your set then check convergance amp ic. http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm
