After replacing LCD, the screen lights up but no picture

I dropped my MacBook air and broke the left hinge, Shortly after that my screen was turned a blue hue. I opened it up and found the LVDS cable was frayed and then my screen went from all blue to completely large pixels. I replaced the LVDS cable but when I reboot the screen lights up but no image. I can get an external screen to work. Going into displays only shows the external display. I purchased a new MacBook air top complete with wires attached but got the same issue. Is my video controller in the laptop fried?

I noticed you never got an answer to this. Are you still having this problem?

Since the external monitor works the GPU and logic board are fine. The problem is all in the display. With the unit showing no internal display I would go back to the display data cable. Also how reliable was the display supplier?
