The monitor has an independent mains power supply (not via the base unit and works fine with my older machine) so I don’t think there is any problem there.

I don’t have the pleasure of seeing anything at all unfortunately the monitor just switches itself on and off intermittently with a frequency of around once per second. Whilst the monitor is on all that is displayed is a blank white screen.
Thanks both for taking the time to reply and try to help me sort this out.
