Hi all, I have recently received a C1 that does not have a working screen. When switched on, nothing comes on the screen and the Ext CRT light is permanently lit (regardless of jumper settings in the back). This seems to be a common problem among these and may be more reflective of some sort of general error than a screen issue per se.

Anyone out there familiar with this issue or able to suggest any basics to check? Ultimately, if it's not an easy fix I'd prefer to have someone who is well versed in computers look at it.
