My lamp is out, amd would need ro buy some time until i can get a replacement lamp
SOURCE: Lamp failure indicator
I had the same issue when replacing my lamp for the first time. I replace just the bulb with the Phillips replacement bulb. After installing the power down issue started and it would take up to 7 attempts before the TV would stay on with a picture.
Since I never had this problem until i replaced the bulb i decided to send the new bulb back and replace it with a difference one. In my opinion replacement parts are never made to the same standard as original OEM parts. This TV is definitely very temperamental in regard to the bulbs.
When the second replacement bulb arrived I decided to not only replace the bulb I also cleaned the connector plug in the cartridge with a QTip and alcohol. I did the same for the plug receptor in the TV.
When I replaced the bulb i insured the the top of bulb lettering was facing the handle of the cartridge so when you put the cartridge back in the TV the top of the bulb would be facing you.
I also cleaned the entire inside of the TV where the cartridge is inserted including the screws.
Once I did all this the TV turned on the first time and has been working fine for three days now.
I do believe the replacement bulb position is very important as to how it heats up and determines when it needs to cool.
I hope this helps others with the same success i had because I really do not want to replace this TV and start replacing all the parts others have done with little to no success for this issue.

The lamp is not that exspensive you should be able to get one for around $150 and you can replace it yourself.
The lamp can be bought as a lamp or you can order the entire cartridge, I would suggest the cartridge, unless you are handy at taking things apart as the cartridge can be tricky to take apart without breaking it. The only difference will be the cost. It is your choice. The Mitsubishi part number is 915P020010
You can google this and find many places to purchase the lamp or cartridge on line.
Replacing the Lamp Cartridge Tool needed: Phillips screwdriver
1. Turn the television off and unplug the AC cord.
2. Remove the front speaker grill by gently pulling on each side. The grill will snap out.
3. Using a Phillips screwdriver, remove the three screws (one on the left and two on the right side) that hold the recessed plastic cover in place.
4. Remove the plastic cover and set aside with the screws.
5. After removing the cover, you will be able to see the lamp cartridge. With the screwdriver, loosen the threes crews of the cartridge. The three screws will not completely remove.
6. Gently grasp the metal handle and pull straight out (towardsyou).
7. Insert the new lamp cartridge securely into the TV. Do not touch the glass surface of the cartridge.
8. With the screwdriver, tighten the screws on the lamp cartridge.
9. Replace the plastic cover and screws.
10. Snap the speaker grill back into place by pushing it into place on each side with the palm of your hand.
I hope this information allows you to resolve this issue.

Pull off the panel below the screen.
Remove the two screws hold the 2nd cover from the left.
Remove one screw from the lamp module and pull it out.
Buy the lamp module. It is not worth it to try replacing the lamp. You can damage the bulb easily.

Actually you must replace the DLP chip that is buried deep in the works of the tv. Unfortunately this can run into a nice lump of change. Do what I did. Perhaps you've heard the old addage
