Question about Yamaha DSP-A1 Receiver
The display problem is because the solderings on the back of the display are broken. To fix it you have to open the amp and redo the solderings (there are about 50 or 60 of them). There is a Youtube video that shows how to do it. I have fixed this on my DSP-A1.
I also have the problem with the motorized volume control. I have tried cleaning it, and it works for a few days, then it's stuck again. I guess I will have to replace it to have it fixed permanently. The part number is VZ621400, a new one costs about 40$.

Sounds like a capacitor problem in the power supply to front panel display,another common problem is everything o.k for a few miutes since power on then goes off like you say which could be down to dry joints on the vacuum display panel whick go open circuit when everythig warms up (open circuit meaning non contact) in non tech term.
