Can't play mp4 files

The mp4 files must be maximum 320x240 resolution, any larger and it will tell you that the file is not supported. If the mp4 is created with any profile other than "AVC Baseline" it will tell you the file is corrupted. It also won't do DRM, but I can't remember what, if any, DRM systems typically get used on mp4 files.

Nwz-e438f will not play, or connect to computer

Please try connecting the Walkman to a different USB port on the Computer and check if that helps.

Please make sure that there is no other USB devices connected to the Computer at the same time.

If there was no change after the player was reset, connect it to the computer and reset it again, leaving it connected.

Keep the Walkman connected to the Computer for 4 hours to fully charge the battery. Then, check whether the Walkman is working properly.

Ensure that the HOLD switch is not activated.

If the issue still persists after performing the steps provided above service of the Walkman is required.

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.

Mp3 Player Froze

Follow this procedure if the portable player appears to be frozen with Every Moment Has its Music on the display.
  1. Confirm that the portable player is connected to a working USB port and that it is charging. If necessary, connect it to a different port. When connected properly, the battery icon will be animated or it will indicate the charge status such as FULLwhen charging is completed.
  2. Make sure that you are pressing the POWER button to turn the player on. Previous Walkman models that did not have a power button would turn on by pressing any button. This model must have the power button pressed to turn it on.
  3. Ensure that the HOLD function is not activated.NOTE: For some models, when you use the portable player for the first time, if you have not used it for a long time, or the battery is depleted, it may take up to 5 minutes for it to be recognized or start charging. On models with a display, the display will remain blank. If it the portable player is not recognized or does not begin to charge after waiting 5 minutes, continue with this procedure to reset the unit.
  4. If the portable player is still not responding, reset it by pressing the RESET button with a small pin or similar object.NOTE: When the RESET button is pressed, although the unit will retain the music data and clock settings, all other stored data and settings may be deleted. If the unit starts up after the reset, access the Settings menu and initialize the unit using the Format (initialize) function.
  5. If there was no change after the player was reset, connect it to the computer and reset it again, leaving it connected.
  6. Check the Sony Support Web site to see if there are any available firmware updates for your model. Updates can be found on the Sony Support Web Site in your country.

I dont know how to

There is really no power button only OPTION/PWR OFF button of your player.
If you press and hold the OPTION/PWR OFF button, the screen turns off and the player enters standby mode.
If you press any button while the player is in standby mode, the "Now Playing" screen, etc., appears
and the player is ready for operation. Furthermore, if you leave the player in standby mode for about 4 hours,the player turns completely off automatically.
If you press any button when the player is turned off, the start up screen appears first, then the "Now Playing" screen appears.
