MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:
UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR A MOMENT AND GOES OFF.
PRESS AND HOLD "device"(input) and"menu" buttons on front of tv for at least 5 seconds and then release bothtogether.
Watch for power light to blink in a sequence:
1 blink-then 2 blinks-------no error
2 blink-then 1 blink-------X-ray
protection2 blink-then 2 blink-------SHORT PROTECTION*******
2 blink-then 3 blink---------deflection circuit problem
2 blink-then 4 blink---------vertical circuit problem
******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.
SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.
IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM
let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.

SD TECH
Rear projection TVs have a bulb that needs replacing every 4-8 years or so. This usually gives you some other indication though, like a blinking light or something of that nature. (but that's what this could be)
If it's not that, did you have a power out just recently?
If so, you could be in trouble.. The TV's video board could be fried. (worst case scenario)
This could be a fuze as well, but too hard to tell. That clicking you're hearing is most likely a video board being power up, and then shutting itself down.. You may want to call Mitsubishi for this one, but consult the owner's guide about bulb replacement first. If there is supposed to be an indicator light for this and there is not, call them.
I hope this helps a bit.
