Cheeky whippersnapper :) Neil has been an electronics engineer for nearly thirty years and knew what he was looking for... and if one 70 had a fault in one of three power circuits, it was a good place to start looking. > > Now the issue with this 110 MB is that >nothing< works when the system is > powered up.

Silly question I know - but is there anything coming out of the video socket? Is it just the video screen that's dead? If it is, then it's likely a fuse or other component of the voltage supply to the screen; the lamp driver inverter, perhaps? Neil
