Hello, brand new to this forum. I have a Pioneer PDR-555RW I purchased from a fellow who hardly used it at all, after a few months of enjoyable recording and playback, I put a rw disc in to erase, and after the erase process was complete, I had a power outage in the house, and after Power was restored, I pressed the power button on the recorder, and all I get is the green flashing light and no displays, and I cannot open the tray. Any ideas on what is wrong? I am a complete electronics novice, so be kind please. Many Thanks!
