OK, worried as much. Is repair something I could do myself, looks as if it slots in

Yes it depends on your DIY skills.

You will have to unplug it and pull it out.

Then remove the side panels and towards the bottom right you will see the power module.

You can remove it and replace it.

Customer: replied 9 days ago.
OK, great. I'll try and remove the old one before ordering. What is the possability that it is something else though?

If it was something else it will at least light up.

You can remove the connectors on the control (one at a time) and then reconnect them,see if it helps.

If not you will have to replace it.
