I am having the same problem. Got mine 4 days ago and started having the problem yesterday. Would not power on, did not think to check if the screen was just not powering on from the tip above. However, when I plugged it back into the charger it would then power up. Now the screen has "smears or vertical lines" through it. I can get it to boot and work but the screen has not fixed itself. Is mine toasted as well?
