Small section of screen unresponsive to touch

Hi all,

My gen 5 had a damaged digitizer and LCD. It worked fine except the top right section wouldn’t operate by touch and some lines vertical and horizontal from this area. I replaced both the digitizer and the LCD. What is interesting is the exact same area of the screen still doesn’t work. Any ideas? Thankyou

What I’m finding odd is the screen test shows it to be improving by touch yet when trying to touch the screen in normal view it isnt any better than the original area that’s not responsive.

@axelhow since this is the identical area that is unresponsive my money would be on the touchscreen IC or possibly the connector being an issue. This sounds like a board level repair and you may need to connect with people that do that type of repair. I’d be contacting @refectio or @imicrosoldering and see what they have up their sleeve.

Oldturkey is right. I would carefully inspect the connector first. If you have a multimeter you could check the connector in continuity mode by putting one probe on the pins with the other on the pad. You could than check in diode mode with red probe on ground and see if any lines are open or compare the readings to a known good board.
