HP vp6111 DLP projector, manufacture PN L1707 Serial TWB4173993 lamp USHIO type NSH200BQ wattage 200. April 2004 is manufacture date.
The projector started shutting off after running for a while. Based on what users said, it would run a few minutes and then shut down. After it sat for a while they could reconnect and it would run OK but might shut down unexpectedly. The last time I set it up it started normally but the projected images of windows desktop were yellowed and left side was blue and blurred. I shut it down by using power button and it went into normal stand by cool down mode. When I came back to it an hour later it was shut off. It is now total dead and does not respond to any power on mode, connected or not connected to anything. I suspect the bulb is bad but have no way to test and do not want to buy a $400.00 bulb and find the problem is something else. Can a bad bulb cause the project to act this way and stop it from turning on or what would be the cause?
