Not Responding to Touch
I received a 6 Plus that woud not charge or power on for repair. I replaced U2 (TriStar) and Tigris... After receiving about half the voltage it should, I tried to power it up but still would not power up. I double checked for shorts and found one near Meson IC. I removed Meson IC and Short went away, so I replaced it with new one. No Short now.
Now, Phone boots up fine but not responding to touch. It is a tested Screen that works, no damage to Digitizer FPC Connector so I removed Meson and tried another...Still same issue (Not responding to touch). Any suggestions on what to check next?
Is this a good question?
