We had an issue where one of our VL2500 where it completely died. We sent it off for repair and then hung our spare that we just picked up from the repair shop. Now our spare that was just fixed is not homing properly and the LCD display will not turn on, but the fan does. It apparently points at the ceiling and only homes tilt as far as I have been told. I have had them check power going into the unit as well as trying to home it from the console and power cycling it. Thoughts on what further to try?? Edit: I forgot to mention that power for this unit is running about 100ft over 12/3 edison.
