I have the same problem. I have owned my M13 (bought new) for about 2 years. I have used it at home, it has been well-cared for. Firmware is the most recent version. I have tried a friend's M13 power supply which I know to be working, and the issue persists. Happens as soon as the unit is powered up, channel blinks with all sorts of erratic behavior ensuing. Unit is completely unusable. I really like the M13 and hope to be able to fix this issue. Has there been any solution offered?
