Hi dB C, Ordering a new LCD might not help. Since you are replacing the battery and the LCD was good before, replacing the LCD would not help. The problem is with the Zif connector where the LCD ribbon cable plugs in. If it does not have good contact, it would not work. From my own experience, I tried to connect and disconnect the cable a few times using different mylar pieces. I was ready to give up when by pure luck, I applied some pressure to the area where the connection located and voila, the screen turned on. I would suggest to try it again with different "tape/mylar".

I ran into similar problem on an IPad 3 and was able to fix it. The black retaining clip was broken off. I found this article but it was for the digitizer, not LCD: Digitizer(Touch screen), Not responding after Tear down. The fix is similar to either case. I used a thin plastic piece, cut to the size of the ribbon cable and push it in, on top of the ribbon cable to thicken it. Instead of the mylar tape, I re-used the screen protector from an old Nintendo DS and cut it to size. I did not think it would work but it did for me after 4,5 tries. I believe any screen protector would do, if you do not have the mylar tape around. Good luck.
