I have CapAc, which after certain time of unstable working behaviour just decided to die completely.
I opened the case, disassembled the board and found that the element U5 overheats extremely. On a capacitor next to it I measured 8ohm which is an extremely low resistance. I desoldered and measured the capacitor and it gave high resistance and I assume buck converter IC has passed away. It has some markings reading mY2104 which gives me nothing when googled. So any help from mikrotik will be highly appreciated.
