I hae had the TV for three years and never a problem. Today, I turned it on and the power green light came on for a few seconds. I heard a little crackling noise. The light went off, then came back on, went off, then came back on and now turned off for good. Any help would be greatly appreciated. Thanks.

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.
IF model number posted is correct and green power light comes on for a few seconds and then goes off: On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.
Power light will then blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.
Let me know what error code is found and I will tell you what it means.
i think the convergence amps are weak, or the akb circut has caused the tubes to go bad, google your model number to see if it is in the tube problem. sony made some projos w/ bad tubes in them. tv lasts only three or four years,no cause i had one
It sounds to me like your bulb has burned out. Look behind your TV for where the bulb housing is and pull the bulb out to check if it's burned out or not. You'll know when you look at it if it's toast.
You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance: 1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours 2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris. 3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle
Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!
I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
