I have a old but functionable panasonic/Sony SJ-MR230 Portable Md Player buit can't find the 4.5 charger to fit. Any suggestions?

"MF"? What does that mean?

Does this happen with other discs?

This is a best guess for an odd situation.

It could be you corrupted the MD somehow and can no longer play it. Since it is a portable I had a similar instance where I played the same song many times my disc did the same thing. I may have been running and giggled it at the wrong time. It is not impossible to mung a minidisc just unlikely.

Other options are you got dust in the minidisc and it is blocking the laser. I think I would try to make another MD of the song. If it only does it with a particular disc it is the disc if it does it will all of them the laser mechanism may be wearing out and is mechanically unable to slide to follow the track. I once lubricated the worm gear which moved the laser in an old portable which solved a similar situation.

To be honest it probably is not cost effictive to repair any but the most expensive MD decks.

I'd suggest you look for a working twin to yours on ebay and buy it.

I spent $350 to get a high end MD deck repaired and the repair only lasted six months. This is even more true with portables.

Watch out for any portable with odd rechargable batteries, there are several legendary protables which cannot be used as the batteries have not been made in years. Replacements if found are overly expensive and probably old, used replacements have little life left in them.

Most Sony MD remotes will operate most functions on this unit, almost all of the Sony MD remotes are available on ebay even the rare ones.

Page 121 of the Manual states that on the Net MD you cannot delete tracks, groups or the entire disc contents.

In other words you need to have it connected to your PC to Add & Remove tracks.


Please leave feedback

i understand (i've gone through 3 sony md recordable players & now i have about 15 - 20 md with good mixes from clubs/carribean islands beach partys) the only thing i can suggest is invest in another mini disc that is capable of playing the 74 min disc (and speed that was recorded) here are two sites to check out 1--http://shopping.yahoo.com/s:Portable%20MiniDisc%20Players and 2-- http://www.google.com/products?hl=en&q=mini+disc+player&um=1&ie=UTF-8&ei=OhkbSozEApC6tAOr9NCSDw&sa=X&oi=product_result_group&resnum=4&ct=title

had the same problem a few minutes ago!
removed the battery but it didn't help.
tried with another md, no success
tried the same md in another Mz 910, no success

then it got on my nerves and I gave the MZ n910 a little shock with my hand.

It worked, stopped spinning and started to play.

It was, I think, a spinning problem, md couldn't play properly, the little shock helped.
