Love my HLP5067, however, having to get service today because on several occasions recently, the picture has refused to come on and and set itself just cycles on and off repeatedly on its own for no particular reason. Unplugging the set for various amounts of time seems to solve the issue...it's not the lamp itself, but has been explained to me as a "ballast" problem in the lamp assembly analogous to the ignitor not working on a grill.
