My fan has become rather noisy recently.
Ditto! Is anyone else having this issue? I'm on PJ#2 (first one had the red line issue after 200 hours). I just hit 900 hours on this unit, and my fan sounds like it is dying. It actually sounds like the fan blades are rubbing on something. If I put it into "high altitude mode", the fan speeds up and the noise goes away.
I took the projector apart today just for giggles. There are several blowers inside, but the culprit appears to be the exhuast fan located towards the front of the unit by the grille. It is a Nidec Ultra Flo U92T12MMB7-53. I thought I might just replace it myself, but I'm not having much luck finding a suitable replacement. It seems Epson opted to use a 3-wire low pass/high fail locked rotor alarm signal (rather than a tach signal), which are hard to find. If anyone has any leads, I am all ears. FWIW, here are the rest of the specs: 92X92X25mm, 12VDC, .10A, sleeve bearing, 7-blade impeller (Best guess is its a 34CFM, 19.5 DB, 2050RPM unit).
I suppose I will call Epson and try to get another projector soon...
