Toshiba 52HM95 52-inch HD DLP Projection TV - Blank Screen - Getting worse!

[HDMAN]

The problem: What I am experiencing is my screen goes completely black (no lines or faint images), while the audio remains on. This is occurring at least once a day, sometimes two or three times every day now. I have had the TV since new in 2006, with this problem starting several months ago.
Temporary Actions Attempted:I can switch channels and the screen will come back on about 30% of the time. If this fails, I must power down and up again for the screen to come back on again, which always works.
Help Requested:Is anyone familiar with this problem and if so is the solution to it within the scope of a novice?
Please advise.
Thanks

Does it require a new lamp? 2006 was some time ago as far as tv's go.

Thanks for the response.

I have had to replace the bulb at least three times in the past 10 years but that was due to it burning up with no picture at all. I believe this case to be different although I am not sure of anything at this point.

bulbs do fail is other modes than just "burn up". Your only other option is the ballast. However, neither bulb nor ballast can be tested without a known completely working system (ie. bulb and ballast certified working).

...just replaced the bulb and the problem persists.

that would potentially point to the ballast next.... but you should do a few voltage checks to ensure there is some "base sanity" electronically for the system.
