Optima HD20 DLP projector boot up issue
Hello, all. I've had this projector since 2009, and its never given me a problem. A few days ago the picture and lamp turned off while watching a show, and the fan turned on and initiated the "cooling down" phase. (Honestly, I'm not sure how many hours are on the bulb, but i'd guess more than 2000)
After the projector fan finished the "cooling down" phase, I tried to turn it back on and the power light (which was amber as it normally is in standby) turns green, but flashes 3 or 4 times - and then nothing happens. No fan, no lamp turning on, nothing. I figured the lamp just needed to be replaced, but after replacing it, nothing changed. I did some googling and didn't find anything definitive on what the failure was. A bunch of posts suggested opening it up and cleaning out the dust with some compressed air, that maybe the fan was gunked up. Tried it - nothing changed. After opening this thing up, I'm pretty impressed, it's really clean.
Anyone have any ideas?
