A while back my daughter purchased a mp3 player. It sat around and this afternoon I loaded it with some music for my grandson. After it was loaded it would not play. When we opened the battery compartment an ugly surprise, the battery leaked. I found this advice on the net. Will try it tomorrow.
Clean battery contacts. You can use an eraser on the end of a pencil to clean and polish battery contacts. If batteries have leaked and corroded, try using ammonia on a cotton swab to clean the contacts first, then polish them with an eraser.
