There are a couple of possibilities on the last page...
Today I was changing the housing on my T720 along with a new screen to replace my cracked one. I got everything put on and it looks nice, however my volume up and voice memo didn't work afterwards. I took it apart again to take a look and compared the buttons that didn't work to the volume down button that still worked. It looks like the little buttons simply are pushed in and I can't get them to pop back out. The oem housing was really scratched up so I wasn't too careful removing it so its possible they just broke off. But is there some way to get the buttons to pop back out, if anyone else has seen this problem. Or can I buy a replacement the circuit board. Sorry for such a long post. Thanks for any info you guys can provide.
Thanks for the response. After taking the phone apart again, I've concluded that I broke off the two buttons. I guess I'll look into getting a replacement board and be more careful this time around.
