Help with Optoma HD70

Hi there,

My roommate and I have an Optoma HD70 that we've been using for about 15 months. Recently, it developed magenta/green color flickering, so we took it apart and cleaned it following a walk-through we found online. Now that it's back together, the LEDs on the top light up, and pressing power gives the green LED like it would be turning on, but the lamp, fan, etc... don't turn on or make noise, or anything. If we let it sit for several minutes, the lamp light comes on. When we took it apart, we did disconnect all of the cables from the main board, but they're all back in and secure (we've double-checked). What could be the source of our now non-functional projector? We've put a new lamp in, and it doesn't work with either the new or old lamp.

Thanks for the reply! My roommate was able to figure it out - when we reassembled the projector, we didn't have the large connector built into the bottom of the main circuit board connected properly. I'd seen that micro-switch issue, but tested and realized that wasn't the problem. With the lamp cover off and the switch open, the LEDs on the projector don't come on at all.
