Rift S.... Black screens in headset!

Any one encountered Black screens in their Rift S headsets?

Ive done all the google searched fixes to as yet no success.
Updates, drivers, different USB ports, resets … oh dear …

Not keen on buying another rift S headset in case its my computer that is the issue…

Any inside knowledge available here ???

Finally back in VR !
