Can't turn on my Miniplayer M6SL!!

I have a serious problem with my player -it started turning off now and agian with no reason and with its battery full!finally i couldnot even turn it on.I read the FAQ and tried everything-hard reset, rescovering a dead player -nothing helped.I 'd really appreciate some help.Thank u .

How long time have you had it?

5-6 months

Try leaving the M6 in the charger for 2 hours. Then unplug it and see if it stays on.

i tried it it didnot work out.Once i plugged in and turned it on - a white line appeared on the top of the screen- 2 hours after when i unplugged it and turned it on i didont start working-just a black screen.10x anyway
