Well I replaced the screen with a Version 1.4 and the only screen function that works it the back light. I traced the connector for the screen to the phone. It goes under a thin silver plate covering the rest of the connectors circuit board. I found that it is only held on by 2 small double sided stickies. Under the silver plate on the circuit board if found the following:
LG CU720 LCD Screen ********** - 1.2
Now I'm going to go out on a limb here and hope I don't fall, but I'm going to get a Version 1.2 screen and try it. Since the screens only cost $13.00 each, I'll now have $26.00 invested on this fix. (Hell of a lot cheaper than a new phone!)
I'll be back and post the results when I get the new screen and finish. Hope this helps someone!
