Well, I've had 2 XBR800's with bad lamps......and I think I replaced one Lamp Driver board Weird thing about this is the symptom.....TV illuminates, about 30 - 60 seconds later it shuts down (the lamp does), then about 30-60 seconds later you hear the Lamp fire, lights up quick.........runs about a minute, then shuts down again...... You would Ass-u-me it acts like one of the thermoswitches is kicking in/out or the Lamp Driver board is shutting down, but it's actually the Lamp at fault.
