dfk41 Other than that, I think we both know who will be along shortly with the right answer!
Pff… @Rob666 It could be a bad connection, if the LED is not on, it means the main board either:
- Isn’t getting power for some reason
- Has failed, for some reason.
If you have a voltmeter and know how to use it….might be worth checking whether the main board is getting power. If it’s not, then work back towards the plug.
