I have 2 systems with a benQ drive, and they are both doing the same thing. They will load to dashboard, one is modded one is not. Neither drive will open tray, or read a CD/DVD if I open it and put it ontop with the magnet. All circuits test with a voltage meter that they have not burned out. I checked the potentiometers. They're correct. Do I need to just re-flash both, or is there something I can do?
