My iPod touch wont turn on at all.I tried connecting to computer and it syncs and it makes that noise when you connect your iPod to computer but the iPod doesnt turn on at all.I thought it wasnt charged but my computer tells me it is fully charged so I dont know why it doesnt turn on. I did connect the iPod touch to a cassete input to hear my music in my big stereo. It played like three songs and then it turned off and from there on it didnt turn on even when i charged it and connected to the computer.What should i do is there a solution?
