Could anyone please advise where my nephew could look for this problem. The dmd was working last night, turn on today and no dmd at all. I don't know DE layouts etc so need a bit of help. He is close to being a qualified sparky so has some tech sense. My problem is he is holidaying in Sydney so I can't go look at it for him. I asked him to reseat the connectors to the dmd and no difference. Don't know what fuse is connected with the dmd so do not know if fuse blown
