The folks at Cheng International (the distributors) told me there was no service manual or schematic available for my 8725, and that I had to send it to Indiana for service.
While I'm handy with a soldering iron, I'm not so good with modern surface mount components and wouldn't want to do additional damage trying to replace some blown component, even if I could identify it. I don't think service is feasible without specialized tools for de-soldering/re-soldering SMT components.
