sony walman mp3 player

[brothmix]

I have two sony walkman mp3 players,

one is  NWZ-B142, the other NWZ-B133

The drag and drop simplicity is good, but both are enormously tempremental in terms of the screen going blank for long periods (despite resetting using the button at the back).  This is extremely disappointing, since they players aren't dirt cheap and the software problem is so evident that it must have come up during product testing.  Does anyone have any experience or advice with this issue?

all best,

Hi brothmix

The Walkman screen will always go blank after a few seconds to save power, this is not a fault but a design feature to ensure battery life.

The screen will become active again once a any button is pressed.
