Thank you in avance. My unit is running for a little up to 400 hours, when it shutted off. The lights at the rear were blinking, not according to the user manual. The fact is that when I turn on the projector it works for a short time and turns off. The red light keeps blinking. My space behind is more than adequate for cooling. Since I live in Brazil, there's not a Sim 2 servicing unit. I'll have to send the projector back to Miami. No hot air is coming from the exhaust vent and yet I can hear some noise internally. rovingtravler thinks I have a problem with the fans or the temperature sensors, i don't know how many the pj has. I' mworried about, talked to my dealer , who came in my house, and an specialized projector tecnician will have a look at it.
Do you have a possible dignosis on the issue. Sorry for posting here, but it's the only recent thread. Cheers. Waltie
Sorry for the late response, but I just noticed your post.
Your problem could be one or more of several things, all related to heat. First, there could be obstruction of any of the air intakes or the exhaust vent. When my projector is on, you can easily feel warm air exiting the ventilation holes at the right rear of the projector. You can also feel cool air being sucked in several other areas: from the left front (looking at the pj from the front). Also cool air is sucked in the left rear vent hole (looking at the pj from the rear). If you shine a bright flashlight in either of the rear ventilation holes, you won't see a fan, but it should be free of any debri or obstruction. The manual says to use a vacuum cleaner in suction mode to suck any debri from these vents.
To my knowledge, there are 2 fans in the MICO 50; one associated with the water cooling radiator to cool the LED's, and the other fan moving air to cool the electronics. Both of these fans are quiet. My guess is that rovingtravler is probably right about one of the fans not working because you can't feel any hot air exiting. Since it only takes a couple of minutes to overheat, I'd also guess it is the fan associated with the water cooling of the LED's.
If you have a technician who is careful, it is easy to remove the top panel so you can inspect the fans. I believe only two screws need to be removed. If you look at the review that cine4home did, they clearly show the fans and the directions of air flow. It also shows how easily the top panel comes off.
Another workaround might be to put the projector in high altitude mode in the user menu. This will cause all fans to run in high speed mode all the time. If this keeps your projector running, it's a pretty good bet you have a fan problem. I recommend reading the cine4home review as it will show you the internal details.

Good luck in getting this resolved.
