Quoted from bobwiley:The final fix was sending it to ChrisHibler He repaired the driver board (a-12697-1 )and the MPU. It was fantastic. Works great now, his communication and turnaround time was awesome. He even sent me a video link of my board repair. He replaced some parts and put the nvram replacement in so I don't have to worry about batteries. My only regret was not sending it out sooner since I was dealing with intermittent problems for months. Thanks to everyone for helping me narrow down where to look for the root of my problems!
