LG6100 screen inverted / no outer display

Hey all,

I should probably just get a new phone, but all of a sudden my LG6100 has no outer front display and the inner screen has inverted all the colors. The text is also a bit blurry. Any ideas greatly appreciated, as I need a phone at all times for work. I don't care if the screen stays like that, but its critical the whole phone doesn't fail.

Thanks
