Surface pro 3 had weird issues with touch (jumping all over the place). Teardown revealed that part of the touch controller cable is disconnected (it was bent a bit, I think it was a previously botched repair attempt). I see the touch controller cable has glue all around it. I am going to try cleaning the disconnected part and reattach the cable using non-conductive glue. Should I look for a replacement digitizer for that piece? I think at current prices it will be cheaper to replace the entire device.
