My JNC SSF M9 20GB MP3 player not working

Try delete everything in the MP3 that isn't .mp3 format, if this doesn't work then you can try to download a program that will format it.

I have the same player. The AC cord I use just plugs in, there is no transformer or anything. I am not sure what to tell you - just the cord has the following printed on it, not sure if that will help.

AWM 2468 VW-1 80 (DEGREES SYMBOL)C 300V E157717 18AWGX2C JHI WEI CSA

I hope this helps.

it might be that u have saved the files in a different place without realising or u have replicated the songs.

and try again to load song

EEK i know what this is , the memory cells or NAND/Flash storage on the mp3 is dying as you cannot delete it , you can try to add an sd/mmc/xd card if your mp3 supports to add and delete songs as it wont be affected it but it wont cure the fact that you cant delete it .

Alternatively you can update the mp3 player firmware by downloading it from the web or you can try to return it under warrently (number in support manual)

As a last resort you can connect it to the pc right click it and press format this will erase all data /everything on your mp3.

I am currently using one from a camera, just look for one with the same connection.
