Model of your discman is ... ?

Possible problem with the power jack/ battery switch, requiring a replacement jack socket

Hi,
You can't put video on it. It's a discman with mp3 capabilities. Meaning you can play shop purchased cds or play cdr discs with mp3 audio data files on. It sounds as though you are confusing mp3 with mp4. Mp4 is a video codec/file format.

In the search bar above, type in the name and model and hit search. good luck

It can be fixed at service center.
