OK, I have a Panasonic PT-AE1000U. Just replaced the lamp after 3 years of great performance and ever since replacement I have the same problem:
About 2 minutes after turning on my system the projector shuts off. I have to power down the UPS, immediately power it back up, then projector will turn on immediately (no cool down time) and will run fine for hours.
I thought it might be the UPS unit so I tried just plugging into the wall outlet. Same problem. Once the projector shuts off (in about 2 minutes) I have to unplug from the wall, plug back in, and then the projector will run fine for hours.
(If I try to turn the projector back on without unplugging/re-setting it won't work....it's like it's stuck in cool down mode).
Anyone have a reason why this just started happening after the replacement bulb? Is it related to the bulb or just projector dying on me?
