My 6 month old 5D Mark IV won't switch on (different batteries tried and so on), anyway I bought this on Ebay new but but basically grey market so no official warranty (I know - I am stupid). The supplier did offer a 1 year international "warranty" in the sale but after sending it back to them seems like bs as they now tell me they only cover return shipping and labour, not parts. They diagnosed a dead PCB and want £205 for the part. After doing some Google research it appears that the Mark iv does have reports of a 'won't turn on' due to pcb power issues. You cant do hard reset like on Mark III as it has no internal battery!
Whilst it looks like I am going to have to pay for a new PCB I am concerned that Mark IV may have an issue with this part and may well happen again??? Has anyone had this or similar issues?
