Epson projector temperature sensor malfunction
This happened after I transported the projector on a wheeled cart. It was protected with bubble plastic but it still hit some obstacles so I'm guessing a sensor became loose. I've already disassembled and reassembled the auto-iris and the sliding filter. All seemed to be good. UPDATE: Since the making of this video, I've fixed this issue. In my case, it had no relation to the malfunction. The way I fixed this temperature issue was by removing the fans and cleaning them. Fans are very touchy, and sometimes a bit of dust or a slight bump of the projector can make them rotate at a different speed causing the projector to shut-down. You can start by cleaning the two fans on the back of the projector, near the lamp. Sometimes it isn't necessary to clean them, all it takes is to take them out, tapping them, and placing them back. There is another fan near the removable filter on the back of the projector, but this one requires much more work to reach. If cleaning/tapping the fans does not fix the problem, then it may indeed be a faulty temperature sensor. Here's other video where I disassemble part of the projector to fix a different issue: https://www.youtube.com/watch?v=DzNIdS4Btsc I can also send you the technical diagrams of the projector if you want to. If the problem is the sensor: I've seen in comments that dropping it from about 3 feet over a soft surface, top facing up, should reposition the temperature sensor, but I'd rather find this sensor and reposition it myself.
