Alright gang, here's the situation. See this collection of publicly viewable pictures for context:
EPSON 8700ub; ECO mode OFF; High Altitude Mode ON
Projector lamp hours is at 17, very recently replaced.
Unit warranty expired January 2013
Air filter is clean
I keep my apartment at 74 F
The unit works for 15 minutes, then powers off, blinks the red light, and turns the fans on super-high for about a minute. Then I have to flip the power switch off and on, then power button. Next go only lasts about 10 minutes, until it gets to the point where I'll power it on, and it will immediately go to overheat-high-power-fan mode.
What I suspect is that with the positioning in the room, the heat venting out of the PJ exhaust is diverted sharply to the unit's left. The air conditioning vent blows air diagonally down and toward the side of the shelf the PJ is perched on. This airflow encourages the hot exhaust air to make it's way back around to the intake on the back of the unit.
I'm thinking of a two/three step solution, the first step involving kludging up a way to direct the exhaust out into the center of the room where the ceiling fan is. Second step is to add an external fan to the projector intake, and possible third step is adding an external fan to the exhaust. Each of these steps should encourage hot air getting away, and only cooled air getting in.
Any of you guys had any experience/success with this kind of situation?
Also worth noting: if I dtop my AC down to 70 F, I don't have any difficulty, but that's kind of expensive : /
