This Panasonic GH6 camera has failed just after one year. Hopefully the supplier will replace it as this is clearly a motherboard failure, and this is not a reasonbale lifetime for an expensive product like this.

I purchased this from Wex. They sent me a return label, sent it for repair. It took some time to get the replacement board, but the camera has been cleaned and the main motherboard replaced. Now returned to me without charge.
Thanks Wex for good service
