I had owned the MSB LS-1/PS-1 combo when Mark Brassfield still headed that company.During the winter months,I would have the same problem.Generally,a 24 hour unplug brought the unit back on line.You might try grounding your rack to "discharge" before coming in contact with the unit or wear shoe wear that won't add to the problem {rubber sole}.
MSB Link and static electricity
In the winter around here it gets very dry. Dry enough to create a lot of static. Today I accidently touched my MSB Link, saw a spark, and the Link stopped working. The only light that stayed on was the power light. There was no analog output. I unplugged the power supply, and replugged to no avail. I then shut the whole thing off and went out to eat. When I returned two hours later and turned it back on, it worked. I thought for sure that I had somehow fried a chip. Has anyone else had this happen?
