I must admit that the red screen of death happens a lot more than I'd expect it to. I thought it was just my Jag until I read that many others have the same issue.
Of course with the CD add-on there's no red screen, just the usual VLM bank but with a picture of the back of the Jag with an arrow pointing to the power input, but I know it's an equal error to the red screen.
When it occurs I just unplug the cartridge and try again, usually takes about three attempts then it's fine.
