Sony walkman NZ-E353 was working fine both alone and attached too a docking station. Next day it won't come on and keeps flashing "HOLD" before turing off.Battery is fully charged. Please...

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.

My SONY WALKMAN NWZ-S545 does not start up. It stucks in "Every Moment Has its Music" loading screen. I accidentally deleted the ".trash" folder in my Linux Ubuntu virtual machine....

I do not know if I had the same problem, but similar. As far as I know, I did not delete the trash folder. However, it would not start. The "Every Moment.." screen would go on, then shut off.When I hooked it via USB to the PC, windows 7, the computer did not recognize it, the icons for it did not appear. So I tried turning it on rapidly, rapidly pressing any button, it flashed on continuously for a shorter period. Then I switched the left-hand buttons down, off ear-phone and off hold. Plugged i9t in again via USB and it went on. It is working. I tried taking it off "hold" before to no avail. Battery was just about dead. So I think what might have happened: when I tried to take it off hold before, the battery was too weak. Because I just kept trying to turn it on while taking it off hold, I caught that grace second when the battery sent a second of power. Of course, this theory of why it now works only holds water if in fact the PC will not recognize the walkman if it is on hold. Another theory is the PC can only detect the walkman if there's a little battery power sending signal to the PC. What ever,now it is working.

On hold... cancel Hold function to activate

This is not an issue with the Walkman player. You can resolve this by sliding the HOLD switch located at the side panel of the Walkman Player (Model specific).
HOLD switch is used to protect the Player against accidental operation. By sliding the HOLD switch in the direction of the ">", all the buttons are disabled. If you slide the HOLD switch to the opposite direction, the HOLD function is released.
