Hi all

I need a little help

My firiend managed to burn out his gopro hero by connecting power supply the opposite way.

There was only one visibly damaged capacitor (C18).

Now I would like to isolate other damaged parts but don't know where to start (I don't have the schematic, I believe no one has).

It would be nice to have at least voltages at certain points of the boards (aren't these TPxx a test points ?).

Or maybe anyone can provide more general solution to find broken parts ?

Waiting for your help.

Cheers,

Michał
