I just turned on my Marquee 8500 and was tinkering around. I accidently pulled the input board with the projector on. It shut off right away and I put the board back in and turned it back on. Guess what? no pic and I didn't hear that warm reassuring sizzle from the High Voltage. No diagnostic lights at this point. I pulled the HV and put it back in. Turned on to the same problem. I left it on and started writing this post when I heard that wonderful sizzle and thought maybe it was coming back to life. No luck and I now have a H-fail light on the back. A few minutes went by and I heard the sizzle again with no new news. Any help would be greatly appreciated.
