I know this is an old thread, but I hope that you still check it. I have an HD 1000 (about five years old), and I decided to use your example. It all went according to plan, but now, when I turn my projector on, the fans start for about a second, then it cuts off and goes back into standby mode (red light on power indicator, nothing else). When I turn it on, both lights go green, then they go back when the machine cuts back off.
Any idea what I may have done wrong? I was using it just a few hours ago, so it should be working fine. I've even double checked the circuit board again, going by my photos.
The only thing that I can think of is that I wasn't super careful about putting screws back where they originally went, but everything seems to fit and it's all secure.
Any ideas would be great!
