iPhone 6S plus touch not working.

history:customer drop the phone.
need to replace lcd.
tried 3 LCD's no luck.

Solution: Jumper C4251 and FL4251
see image

NOTE: all my post is not the only solution.
circuitry has a lot of connections.
always use tester for troubleshooting.
i asure you that someday you'll have your own idea...

thanks for viewing,

Hi, I have the exact same problem after cracking my glass and replacing it. I've tried 5 different new LCD screen so I know it's not a bad replacement LCD or the IC Chip for the touch that's on the screen. I've been trying to figure out what to do from your pictures, but couldn't... Would you please point me to the right direction? Or is there anything else you think I can try before I trash my expensive 6S plus?

Thanks a lot!
