Vertical bar not touchscreen that does not work

view story

http://forum.xda-developers.com – I was wondering if anyone else is having a similar problem. I have a vertical bar on the left side (not edge) that has no response to touch. I tried it even in recovery and it doesn't work. Do you guys have any solution other than changing the digitizer? Sent from my Nexus 7 using Tapatalk HD (HowTos)
