lontano Posted April 19, 2019 Report Share Posted April 19, 2019 Hi, everyone. 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. Quote Link to comment Share on other sites More sharing options...
PhilippeC Posted April 19, 2019 Report Share Posted April 19, 2019 Open it, search for hardened grease and belt. Solve also this problem. Quote Link to comment Share on other sites More sharing options...

I looked on YouTube before posting here but I didn't see anything relevant. The other link suggests it needs to be taken to someone who can repair it, but there is no such person in my area.

PhilippeC Posted April 22, 2019 Report Share Posted April 22, 2019 There are videos about how to change a belt but maybe it is not in english, try again Quote Link to comment Share on other sites More sharing options...
sfbp Posted April 22, 2019 Report Share Posted April 22, 2019 The first thing you need to check is whether the belt IS in fact loose/broken. This will be obvious as soon as you take the main cover off the deck (without disassembling the drive at all, which is quite self-contained). The service manuals (sony) for these decks are pretty comprehensive provided you can understand English, way better than most of the comparable manufacturers. It's actually reasonably easy to get the DRIVE serviced as it is light and can be shipped inexpensively, after removal. There are a fair number of other decks using the exact same drive, too, so a swap is possible, at least for checking purposes. Quote Link to comment Share on other sites More sharing options...
lontano Posted April 25, 2019 Author Report Share Posted April 25, 2019 I appreciate the advice! I'll see what I can do! Quote Link to comment Share on other sites More sharing options...
sfbp Posted April 25, 2019 Report Share Posted April 25, 2019 On re-reading what I wrote in the middle of the night, i will alter slightly what I said. You need to remove the (MDM-7) unit from the deck, and then you need to take the cover OFF and inspect the belt. Pictures posted here will help. Be VERY careful if you are trying to replace belt on your own. We'll try to give you tips, as some before you ended up wrecking the drive.

lontano Posted April 25, 2019 Author Report Share Posted April 25, 2019 Thanks! It's nice of you to try to help! I'm traveling now, so I haven't had a chance to ruin it yet! But I'll take a look when I get home. Quote Link to comment Share on other sites More sharing options...
freddyjollo Posted May 4, 2019 Report Share Posted May 4, 2019 if it is the belt then when you get it out and look at it you wonder why Sony chose just a small thin item. I have a 940 that had been in storage just as yours, when I took it out it wouldnt eject, the tiny belt had stretched in the mean time and eject stopped working.
