Took a look at the capacitors, cleaned the motherboard and "poked" the capacitors - and sudddenly I got sound again. So yes it's a leaking capacitor problem.
Found a guy who sells those capacitors:

That is all very well, but you have to be good at SMC too
in fact *ALL* the caps on the motherboard need to be replaced as they ALL can spew. Also, you need to desolder U402 and U403 as the acid can get underneath them.
I got someone local to me in Australia to do ALL my caps and battery.
