Bad news.  Mine did the same thing.  Mine is the 61", but the internals are basically the same.  I replaced the lamp and the problem was fixed.  Then after a couple days, it died again.  I replaced the ballast, to no avail.  Took it to the certified repair center and they said I needed a new DLP Light Engine.  They wanted $1250 to fix it, but I was able to order one online from partstore.com for $700 and fixed it myself.  No problems since.
Your certified repair center will charge a minimal fee to diagnose and then you can fix it yourself if you choose.
The easist fixes for the lamp problems are A) replacing the bulb and B) replacing the ballast.  Anything else, you'll want a certified tech to diagnose the problem.
