I know this is an old topic but it does happen to me on occasion. So I wanted to tell anyone with this how I fix it.
I use my player for audio books. I downloaded from the library and I am constantly adding and deleting files. The adding and deleteing will cause any computer to slow down.
I do get that green screen from time to time. Sometimes it is just for under a minute starting and stopping, which is a bit annoying. But today it turned green while I was listening and did not go away and it was turning off, I gave it over 5 minutes. It took over a minute holding down the on/off to shut off completely.
Step I use to fix.
- To reset (reboot) it may take holding down the on/off for over a minute.
- Plug into the computer and backup anything you want to save.
- Unplug from computer and go reformat
- Plug back into computer and check for firmware updates
- Copy files back.
- Unplug from computer and all should be well again.
