What is generic parser and why does it show a black screen.
First check if your AV cables are plugged in properly. and if ur playing in HD make sure u have them in right

Plug it into your computer and restore it. Or if it's not jailbroken take it back.
If it is an lcd screen which I'm assuming it is then one of the lamps in the back of the screen has probable blown which is causing it to appear dark. or you could have damaged something else inside...
