Yamaha Digital Desk (N12) Repairs

[lonearranger]

My YAMAHA N12 is having some logic/switching (channels 5-12 and some of the controller sections) are not booting or working as expected. Was wanting any recommendations for techs who are good with digital things such as this - especially if they are able to trace things beyond you need this board replaced.

Ideally Sydney or Brisbane or anywhere in between.

Cheers
