Area-51m R2, no backlight

Last week I broke the screen on my Area-51m R2. I know my way around the internals of a pc so i removed the broken screen. I ordered the same 300hz G-SYNC panel as the one I removed. The new panel works great but I have no backlight in the screen. I have made sure the connector is not damaged. Part numbers for the screens match. The old screen did not light up at all when it broke. I get a display just fine with external monitor. Gaming also is not affected so i think motherboard and video card are fine. I am torn between another screen or replacing the connecting cable. I am open to any advice someone may have. Warranty is not an option as it ran out in February and I did not renew.
