My surf just loses power intermittently, all lights off. After I unplug and plug it back in it works fine. Short in the cord perhaps?
No, that’s totally wacky and unexpected. The first thing we’d do to to troubleshoot is to apply 12VDC to the coaxial power connector via another properly rated “wall wart” or via a regulated DC power supply. Switching power supplies are the most common point of failure in our experience so we’d want to eliminate that first. If the behavior you describe persists it would then be time to talk with your point of purchase about a RMA/repair/new unit.
Thanks, I’ll try to find another power supply with the same ratings.
