Did you get anywhere with these schematics? I have fixed the Channels 1-12 dead issue but still have issues with Chanels 5 and 6. Schematics would help me decide what to try net. I know companies don't like to give out schematics, but since they have stopped support for this (although they have been very helpful to be honest), I would point to the comment in their manual for this unit (introduction 1.1):PreSonus Audio Electronics has designed the StudioLive utilizing high-grade components to ensure optimum performance that will last a lifetime. Well they obviously haven't!! Especially with regard to voltage regulators. So, in the spirit of making this unit last a lifetime, schematics would help!!!
