I'm hoping for a little help. My Series IV stopped working last night. When I power it up, you can hear it turn on and begin to start, but then the green power light does not come on and the controller does not go through its normal start up cycle (board detection, loading library code, etc.) I've tried unplugging the controller and restarting it, but this doesn't fix the problem. Any suggestions short of contacting D-Box? I didn't know if there were any other kind of resets or fixes one can try first. Thanks in advance for any advice or if anyone else has encountered this problem.
