I removed my Sansa clip mp3 player from the computer without clicking the safely remove hardware button and i believe that it caused a short in the motherboard and it no longer turns on or connects to the computer. Every now and again it will start to turn on but then shuts off after just a second or two before it even finishes refreshing the database. Is there anything i can do, even if I have to open it up myself and repair something manually
did you try resetting the device (hold the power switch in the up/on/off position for ~20 secs)
try connecting to your computer with the clip on hold and pressing the centre button as you connect it.
