When iturn on my projector it turns on as per normal(green light), however about no more than 5 seconds the fan cuts out and the projectors flashes a white screen and turns back to standby mode(red light).
I'm not finding anything like this on any other sites?
The globe is under 1500 hours
cleaned out the vent
everythings plugged in correct.
Can Anyone shoot some ideas at me?
"Smart enough to know better, to old to care" ------ Dedicated Home Theater, Mitsubishi HC7900DW Projector, 110" 16:9 Jamestown screen with variable power masking for CIW 2.50:1 to 16:9, Marantz 7009 with 7.1.4 Atmos with Ohm mains,3 DIY Subs (2 15" (1 ported, 1 sealed and a 12" 4th order bandpass), 1 DIY butt kicker, Custom Built HTPC, 10TB DroboFS NAS
Having the same problem with my PT-AE700E.
Projector powers up fine (screen image looks great, fan can be heard) then powers down in 3-5 seconds with both LAMP and STANDBY LEDs on RED.
At this point, pressing the power button does nothing. The ON/OFF switch at the back needs to be switched to OFF and back to ON to allow for above process to be repeated.
Replaced the lamp and no difference.
Been thinking that the LAMP timer needs to be reset but I don't have enough time to enter the menu to reset it, thought there may be some other way to do it.
Then after searching and searching online without coming across this issue much at all, thinking it's not even the lamp.
The TEMP LED does not illuminate, ever.
Hoping someone has an idea what's wrong with this thing.
Thanks for reply.
The lamp that was in there for over 3000hrs I believe is factory, and I replaced it with an aftermarket.
On power up, the image looks fine with either lamp, can even quickly start activating the menus, but no chance to get into the lamp reset portion before the unit powers down.
Can't imagine that the unit would be built in such a way that you're SOL if you cross over the caution barrier of 3000.5hrs even though the lamp is fine, so I am liking your idea that something else is signaling the unit to shut down.
Any idea how to check the fans? I can hear at least 'a' fan coming on when the unit powers up.
There is one removable filter that I can see and no difference in operation when removed.
Not following your instructions to further test fan operation with the lamp out and case open since unit does not power up unless the case is closed.
If you could please elaborate the process.
