Black stripes on screen

http://androidforums.com – Hi, I´m looking for advice please, I have an LG Optimus P500 for just over 1 year, so out of warranty of course, & the bottom half of the screen has 2 large & lots of thinner black lines across it.

I telephoned LG but they weren´t very helpful, simply said as out of warranty send it in & they´ll quote for the necessary repair.
