Hi there. I have a PJ-TX200, that now when I watch it goes light (slightly), then darker (slightly)...enough to notice. This happens every 20-30 seconds. It is slight, however others have noticed and it's getting annoying. I've only had my projector for about 1 year, and my lamp just hit 600 hours. Do I have a bulb problem, a light engine problem, or something else? Your advice would be greatly appreciated. I have a authorized service department near by, I'de just like to be able to tell him what I think is wrong. Thanks again.

Sounds like a "keystone" problem. Your projector needs to be oriented to the screen in an exact manner. Manufacturers provide "keystone" correct to adjust for mis-alignment. If proper orientation is impossible, use the keystone correction of the unit to adjust your edges.
This is a serious issue and It seems as though you have got a defective peice. Either the PJ was damaged when in transit or it was a faulty piece. The PJ could have a defective lamp because if it is trying to trip off on loading , then the chances are that the Lamp is taking intoo much current and tripping off the circuit. Since your PJ is brand new, if it is under warranty , you must take the privilege of free replacement of the part, than to try any repairs. What could be done is to check again for power connections faulty voltage. If not since the trouble shooting was ably done there is not much to check than to take this decision. You must ask them to give you extended warranty and claim for damages if they seems unhelpful. Hope you decide with my advice. Good day
Yeah, thats the bad fault that one. The fault you have described is the main controller board giving up the ghost and stops supplying enough voltage to the fan tp allow it to run, and shutting down after 4 or 5 mins is the safety thermostat on the bulb cutting it out as to not cause any damage due to overheating. My projector had both these same faults, I ended up just buying a new light tunnel after many attempts of glueing mine back together unsuccesfully =(, and to fix the fan issue (without spending $800 on a new controller board), I permanently mounted the insides of an old nokia charger inside the projector, which supplies the fan with its own power source, worked like a charm =D. Yes I would be more then happy to send you the service manual, may I have your email adress to send it to?
