Problem with new P2 (dead pixels, crashing etc)

[nightcrawler_]

Bought a P2 1 month ago, new. Since then I've had glitches with the touch sensitivity, crashing and now a dead pixel.
One time the player refused to turn on without me using the reset button, another time I was listening to music, screen turned off, I woke it up and the controls were missing on the screen. Then the screen went all funny with lines everywhere and it crashed out. Now I've turned it on 2 or so days later and there's a dead flashing blue pixel at the bottom of the screen that will not go away.
Anyway I can solve these problems, anyone had similar problems and what did you do about it?
I am running EU 5.10 Firmware (BlueWave 4)
