SD many thanks for the prompts,
why is the obvious, so obvious, you can't see it sometimes
It was staring me in the face, as it were.
Did the power options change...nothing.
Did the display settings change...nothing.
Then, it jumped out at me.... the screensaver was set to 'blank' and was behaving as it should. Set it to 'none' and roberts you're father's etc.
DOH! wot a dumbo.
