I bought a broken one of these for $50 with the hope that I could fix it. It had fallen about 3 feet and was totally unresponsive after that. I just finished pulling it apart and I found a couple components on the PCB that have broken solder joints. Unfortunately they're all SMD and are going to be next to impossible for me to fix.
So the moral of this story is carefully inspect all of the PCBs for issues. Also I will be uploading the repair manual to demonoid shortly.
