Sharp 7" LCD

I bought a 7" Sharp LCD Screen (w/ AV,Cable,Antenna, Speaker Inputs) about a year ago, and about a month after i bought it, the screen starting going up and down very fast. I tossed it in my attic, and thought it was done for. Lately, Ive been cleaning out my attic and i came upon it. So i unscrewed the casing, and unplugged the wires that carry the video. I left the power plugged in that goes from the Screen to the motherboard. I then plugged the 12V power in and the screen turns on fine(remember, there is no video connection to the motherboard, just the power connection). The thing is I tried rerouting the Video wire (the yellow one that goes into the back of the screens chip) and i tried hooking it up with a DVD Player Video Cable, and I got no picture, the power was turned on and the screen was white, and everytime i put the 2 yellow spliced wires together nothing came up. Any Suggestions?

BTW, the version is a LQ070T5BG01

It broke after a month? Don't they have warranties where you live?

Yeh it had a warranty, but it wasnt covered. The tv was still 'operating' and it was a user inflicted damage so they told me it wasnt covered.

User inflicted? What did you do to it?
