Touchscreen not working even after replacement
I have a water damaged 6s+ which worked mostly fine after taking everything apart and cleaning it. Charging was very slow and it sometimes crashed but everything else worked. I thought maybe a bit of water was left and I took it apart again and dumped it in isopropyl. Then I changed the battery to an older original one and reinstalled iOS. The problems are now fixed but the touchscreen isn’t working anymore (worked before the second taking apart). Even with a refurbished screen replacement it still doesn’t work. There is no visible damage anywhere on the board that I can find and I checked the screw holes, I definitely didn’t use any wrong size screws.
I have no idea why the touchscreen doesn’t work. Any advise? I guess I have to return all parts and sell it as damaged if I can’t figure this out :c
EDIT
Looks fine to me. Here are some pictures
