Why isn't my iPhone touch screen working?

iPhone 5

Episode 1641

Tom from Burlington, VT

Tom's iPhone 5S died, and he bought a new iPhone 8. But he's not having luck with the 3D touch option. It just doesn't respond. And at other times, it seems overly sensitive. What is going on? Rich says that since the phone is still under warranty, it'll be worth going to the Apple Store and have the digitizer tested. If you don't have one nearby, Best Buy is now an authorized iPhone service center. A reboot of the phone will also help.

Why did the touch screen on my point of sale system go out?

Kevin from Palm Desert, CA

Kevin has a point of sale touch screen system and it blacked out right in the middle of sale and didn't come back. What can he do? Leo says that when a screen goes out, it could sometimes be the backlight. If he looks at an angle, he may see a very dim screen. But if it's totally black, that means that the screen completely died. Or it may be a bad cable. Leo suggestions changing out the cable to start. If it's proprietary hardware and software, then it's not going to be user repairable.
