My MP3 won't turn on. Every time I press the ''on'' button it says ''walkman'' and has a loading bar, but then turn off automaticly. I'm not sure what caused this either.

I'm sorry that the Walkman Player is not turning ON normally and displaying "HOLD" message. The "HOLD" message indicates that the Walkman player is set to HOLD mode by sliding the HOLD button on the right side. Please make sure that the HOLD switch is not activated.

If the issue persists after moving it from HOLD position, please reset the Walkman player by pressing the reset button using a sharp pointed object. The reset button is located on the rear of the unit.

Thanks for understanding. Please let me know if you require any clarification.

How to turn on/off the power? To turn on the power Press the Play/Pause button to turn on the player so that the screen appears. ? If there is no operation on the player for a certain period of time while in the stop mode, the display turns off automatically and the player enters standby status.

The same thing is happening to me but I still haven't found anything

my sony nwz-b142f voulme button is not working. I've try to do but its voulme only decreases not increases..?? what to do..?? please help.!

Ok from the main screen, go to the icon that looks like a film strip - center left, hi light it and press the play button > if you have the right format video loaded, it will show in the window, hi light the one you want to play and press the play button. Videos need to be in the w++dows or wmv format.

try holding all buttons and pressing reset several times,it worked for me,hope it works for you.

I've the problem as well. Did you find out any solution? The button is like dead but the screen is on when i plug it in my PC.

Sorry to hear that. Just press the RESET button to see if it solves the problem. If not, go to the Sony Support Center online.

Good luck, and Happy Holidays.

Reset worked for me. Maybe you have to hold it longer? This is the first time I've had to do this but reset did the trick.

I had the exact same problem with my girlfriends sony nwd-b105 mp3 player. I fixed it by downloading the firmware version 1.2, which can be found here at the sony support link below.
