APM 2.6 heat problem

Yesterday, my apm 2.6 board is encounter at heat problem suddenly. It heats very high at red box in picture after connect with PM or USB connector. And can’t connect with mission planner blinking red led fastly. It’s fuse doesn’t breaked but can’t work any function. What is a probblem of this board? Is it problem of circuit or one of chip?

Hi zzsshzz,

It’s difficult to determine if there is a chip damaged or a circuit issue. Sometimes the serial mux is damaged or the 3.3v regulator is damaged, but on those cases I haven’t see the board getting hot, at least the cases I have seen.
