it works fine for a whole year
then all the sudden, every time i try to turn it on, the power led light flash then just goes off and doesn't turn on. i had to sit there and continuously press power button over and over for over 10 minutes then it turns on.

now every time i go and turn it off and turn it back on right away it's fine
but if i leave it off for over 5 minutes, i have to go through the whole process of raging over the power button, watching the light flash a kazillion times before the screen comes on. It is taking longer and longer each time now, soo i don't i just leave it on now. my warranty is already over soo any help would be GREATLY appreciated!!!
