Long shot but , anyone have a Schematic or know someone who might be able to repair ?
I haven't talked with that dude in years, but I doubt he would release his schematics out on the internet. He assumes skilled techs like me are out there in the field that know how to work on equipment without schematics. But there are not a lot of people like me out there anymore.
What are you having a problem with?
Have you turned off the unit and re-seat the ribbon cable?
The rest of it is regular troubleshooting. Because its standard circuits.
