LVDS cable problem causing no backlight?

I have an early 2014 Macbook Air given to me because wine was spilled on it. The backlight will not come on but it powers on and runs fine. I cleaned up the logic board the best I could. When plugged into an external monitor everything functions properly so I'm thinking it has to be the cable. I went to disconnect the LVDS cable and noticed that it looked almost chewed up or burnt on one end!? (picture attached). Is this the culprit for the backlight not coming on? I just wanted to make sure before ordering a new one. Also how difficult is to replace the cable? I couldn't' find any tutorials http://imgur.com/sSniqX7.jpgonline.

1. No tech would write "that's it."

2. Service manuals are not always free. I do see some disassembly tutorials and videos but all presume you are used to working on machines. If this is your first, then you may feel slighted.

Inside management for pros

Opening up a PC or a Mac is always a free video. Inside configurations always not so likely. You can get lucky on a common issue but for deep intensive or not so common fixes I'd leave to the pros.

But if you understand the basic functions of your devices hardware and it's internal applications then these machines become simple... But until then I suggest seeking professional help.
