Faulty Wingsland M5

Just got hold of a faulty Wingsland M5.

On power on all it does is this:-

In App shows battery 0% and also no reading from sensors at bottom.

So first thought was maybe something loose inside or some power issue?

So teardown time 😉

Once I got this apart did notice something on the connector from esc board to main board , on the bottom right 3 of the wires were stripped bare and possibly touching when together? I noticed this before I took plug out, so I know it was not my own doing.

Above is the M5 esc board

Anyway, back to fault..

I have now checked all the mosfets in case they were to blame and all power rails seem to be fine.

Intresting I feel is the fact the app shows battery at 0% , but also the sensors have no value.

Camera works and records fine, so is there a problem with comms bewteen wifi and flight control data?

The R6 is connected and has solid blue light, but in app says disconnected, a clue there me thinks.

Anyway, off to fix those bare wires first as that could be related.
