Anyone out there got any experience of this issue with this product?

I don't, but I would recommend getting in touch with Varilight's customer support:

They've got a decent ticketing system and the service behind it seems pretty good - they've given me detailed technical advice in the past and are seemingly quite happy to send out replacement modules if a fault is suspected.
