I am using Philips GoGear SA3345 4GB MP3 player. My problem is that my MP3 Player won't turn on at all. I thought that the battery must be died and I checked it but it is still operational. I've tried holding the play/stop button as told in the manual, but that to didn't worked. But when I connect it via the USB to my computer, the play button lights up and I can see it on my computer. Please help me!
