So I am still getting LPS failures in Studio Command 700 units. This particular client has had at least 8 failures a year out of 24 units for the last 2 years and they have 3 so far this year. I cant figure out why these are blowing. The units use to be 2-ferd with 12/3 cable over 250' runs. They say that they each have their own power feed now and they are still blowing LPSs. Any ideas?
