780 shuts down

[mercolini]

My wifire d2 shuts down on start up, it’s less then 6 months old. So far I have replaced I have replace the power brick, the main board, and the hot rod. I’m tired of dealing with service. Any help would be great. I’m thinking of just throwing it away and buy something cheaper. I am fed up with replacing parts that customer service tells me it will solve the problem. Not a very happy customer……please help
