For years I kept my MDS-JB940 in my basement, unused. Recently, I decided to put it to work again to enjoy my MiniDiscs. Sadly, for any disc I insert, I receive the message "C13 Read Error" and the deck ejects the disc. I never had any problems with this unit until now, and frankly, it hadn't received a lot of use. It's a pity because it's such a nice device and I didn't enjoy it as often as I should have. I cleaned the lens with hydrogen peroxide and isopropyl alcohol, but that had no effect. Can anyone offer a suggestion about how to fix it? Thanks for reading this. Any suggestions will be appreciated.
