Hi there,
I’ve been using my Sansa for quite a long time, today I faced this problem, when I try to turn on the player actually turns on, appears the loading screen of rockbox and the menu but when I release the power button it turns off.
I’ve tried to connect it via usb cable to my laptop but the same thing happens, after 30 seconds more or less it turns off by itself.
I’ve also tried to charge it with my phone’s charger and yet the same thing happens.
It’s not a battery problem 'cause the battery is full loaded.
Already did the reset by holding the power button, but as I said if I hold the power button it will turn on and off even if I keep pressing the button.
Hope everything’s clear, hope someone can help me, thanks in advance.
