I’m sure you just had the wrong power cord on it. If the Yamaha has an IEC plug in it, try a different PC, it cures all sorts of problems.
All seriousness aside: It is extremely difficult to fault Yamaha for your situation.
Priced at that point, you can’t assume you will get high end quality binding posts. Since it’s not brand new and straight off the production line, it is B-stock. Expect it’s been worn and gone through.
For multi-thousand dollar items, I expect it them to hold up better with some use, and R&R, ie expensively machined knobs with set screws, not push on plastic caps, extensive soft foam packing cushions in sturdy boxes, and of course, a better PC.
