SOURCE: had a power outage while watching tv. Then 3 blinking lights.
This is an on-going problem with DLP sets. Normally you shut the set off and the cooling fan cools the lamp down and then it shuts off. In your case, of which it's not your fault, however your lamp has taken a major hit by not properly cooling down, in turn, you need to replace your lamp at this time.
I suggest in the future if you have an electrical storm and a chance of a power outage while your watching tv, I would'nt play that model or any other model of a DLP set.

Lamp Fan, make sure all fans are running if they run for alittle while and stop Fan is defective.

The grinding sound is most likely the color wheel. The lamp will not fire up if the computer senses the color wheel is not in motion or turning too slowly. It does this to protect the color wheel from being burned.
Something else you need to realize is the fans sometimes make some noise(especially the fan at the rear of the DMD Board).
The Ballast does not go bad that often and is misdiagnosed more times than it actually needs to be replaced. Sometimes the DMD Board is defective and won't send the color wheel the signal to start which in turn doesn't let the lamp turn on. I have read this misdiagnosed as a bad lamp, ballast, and color wheel multiple times. I currently have two of these in my shop at the moment and they were both verified by swapping known good DMD Boards.
There is some very good information available on this site but many times it isn't that simple of a repair. You need to get all the information and verify before buying parts. Most of the time it will pay for someone to have a reputable shop do a repair rather than buy parts that are not needed. I have had three people buy lamps in the last week, and two replace capacitors, only to give me a call and fix the problem correctly. All of these people got the repair tips from the internet.

Most likely your problem is on the DMD Assy Board P/N BP96-00249A . More presicely there is a few bad electronic components on that board that are bad. That board can be repaired by replacing the bad components (and the other few compoonents that are probly going bad and will soon cause your tv to lockup and lose remote and button functions when it fails so you will need to unplug it to get it on again).
Or the DMD board can be replaced .But it is not a cheap board.
For removal and Installation of the DMD board I would reccomend a tv service person because it is in the heart of the television and there are some adjustements to be made when the new board is installed.
To get the new board you could probably find it by just gooogling the part number.
Component level repair would require some experience in desoldering and soldering SMT,SMD , and or surface mount components.The actual components are about $15.00 total so just repairing your board should cost about $125.00 by a qualified servicer (if you were to remove and install it yourself). This DMD board is used in many models and can a few common problems.

SYMPTOMS:
