If you're NOT still under warrantee you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace. Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs. You can also check the board where the components are mounted and resoled any that look bad. Brief power outages may cause the TV to turn off on its own. If you are using a surge protector, try connecting the set directly to the wall outlet. In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer. All can be replaced at a local electronic or hardware store and they're easy to replace If this does not correct the problem, you may need to have your TV serviced. good luck!

This could be part of the text mode, which has to do with the caption. Check and see if it's turned on.

I battled with this for a while before I realized that my 18 month year old had somehow turned on one of the less common closed caption modes. Since the mode was not supported, it just displays a black frame over most of the screen. Just turn it off and you are good to go.

Sounds like you dlp lamp is going out. That's a pretty old TV and if you are still running on the stock lamp this is exactly the type of thing that will happen. The lamp model for this particular tv is the ty-la1001. You can find that over here:
