My walkman MP3 player model NWZ-B183F has stopped working as an MP3 player. It works only as USB flash stick. Even that I have to reset it every time before using. The screen says "Do not disconnect" and even when its fully charged it doesn't turn on.
Are there any files that I can copy into the walkman to make it work again?
I hope to get a practical solution, I tried all the e-support suggestions and it wasn't solved. No does the customer service of my region have a solution
