I'm back with a new problem with my JE510 minidisc deck, and I hope someone here will be able to help me.
So here is what happened first : I bought a mds-je510 player that was sold as working, but I struggled to make it read minidiscs. It was just spinnng a bit and then ejected the disc. It turned out that it was because it's been plugged out for a long time and if I let it plugged in, it reads and records minidiscs flawlessly.
But someday it started to turn on by itself
