machine was in storage for 6 years.
possibly on its side.I dont know
Driver board is mostly working.

Its actully not that bad.
most of the crud in the picture was just cosmetic.scrubbed off.
sure there is some components messed up but the traces etc etc look to be fine.

Thanks for the tips.
Im starting to doubt that the cap has leaked.
Im thinking maybe a drop of water got onto it years ago and rusted out a resister.
hence the brown crap.
I got those tip102s,the 36c's off the the few resistors/diodes off.
the ones where its worst.
no damage to the traces or pads etc etc
cleaned up nicely .
Just gotta replace them with new one and and I should be set.

Got this board sorted today.
Took off a load of resistors,diodes and the tip102,36cs.

got it all cleaned up and its all working as should.
I did find some rust under some of the resisters.

all good tho.
left those caps alone.
never thought to ESR them .They test fine in circuit?
