I have horizontal lines rolling up and down my p902b.. sometimes a white screen., sometimes blue. .. can.eventually. get rid of them by tapping rapidly on screen.. how do I fix that?

What I don't understand is why it works perfectly 95% of the time on Facebook and only about 10% of the time when I'm working in CHROME...
