Long story short, I sold my M13 since I'm focusing less on guitar, shipped it, got damaged in shipping, buyer sent it back to me. There is a very slight dent on the right side of the board, but I took it apart and nothing seems to have been damaged internally (But I'm not ruling that out). The prongs at the end of the power supply were also bent in shipping. I replaced the prongs. I go to power up the board, the screens flash different colors for awhile, then stay on as green, blue, blue, and green. This unit has never been updated with new firmware. Any help as to what may be wrong, or if I just need to send this unit in would be greatly appreciated!
