I have a Steinberg UR44 audio interface that I had in storage for a few years, and now that I want to use it doesn't power on. I want to take this opportunity to learn electronics repair so I am trying to repair it for learning experience.
I am looking for guidance on how to proceed with troubleshooting the problem.
I have checked the original power supply with a multi meter and it works.
I visually inspected the PCB board and don't see any issues, except what looks like a possible broken fuse but not sure. I checked it for continuity it reads 97 ohms, but... -
Has anyone ever seen an interface like this for video card testing, much more practical than typing codes?
