hey lift-tech, I was also curious as to why the we lost the display on a couple of starters after a power spike in long beach. We replaced the drives to get the cars running, but curiosity got the best of me. I opened up the drive, and found the 22 ohm resistor opened, I couldn't find any other problems, so i put a 1 amp pico fuse in place of the 22 ohm resistor. When I applied power to the drive, the display circuit board went up in smoke before I could turn off the power, alot of the board was cooked by this time, so i wasnt able to determine the original cause. Have you replaced the c45 capacitor on a damaged unit and were able to put it back in service?
