I cannot get any of my MBU's to turn on. Tried two different power supplies, which are producing 26.6 volts at the end of the cord that plugs into the MBU. So far 8 different MBU's simply do not go through the startup sequence, the display remains 'dead'. Two of the units I used last October, and they were working then without any problems. The TM's assume they light up and show an error code. All units stored inside, out of the weather. Any ideas?
