espowsong, you should be more specific : what model exactly (link to site of purchase?), what did you do to try to turn it on? wer'e you able to turn it on before, or is it a brand new player? explain with as many details as possible, then maybe someone can help.
On the one I have just purchased, you have a slider you have to set on the ON position (not written), then you push on menu (UP) ; keep pressing a few seconds if it is needed.
Of course maybe you have to charge the device a bit if it is brand new (or kept unused for a long time). But the thing is, you have to turn the device ON to be able to charge it up! (that could be a problem with a fully depleted battery)
