Usb connector broke off
The + and - are the 2 outside pads on the USB plugs, one will be a thicker track than the rest and should be +5 volts, the other side will of course be 'ground' and is normally the broad copper strips on the pcb that go all the way round. If you're lucky it's a single layer double-sided PCB and the + and - connections may be on opposite sides of the board, if you're unlucky it's a multi-layer PCB that has extra tracks underneath the visible ones, they are impossible to repair i'm afraid. If you have a multimeter it's much easier to trace the power tracks, just don't short anything with the probes, choose a part of the track that's not too crowded.Switch on, locate the + and - and mark them with black & red markers, then switch off asap.
Always touch something earthed like a radiator etc before handling the pcb, this minimises static damage. Hope this helps, good luck!
