regarding touch not working anymore after repairs

I recently ran into some trouble trying to refurbish a A53 5G.

not too long ago we took in an almost unused A53 but it had a crack in the screen so we decided to replace the screen to make it mint again. after i tried replacing the screen with a new one the touch suddenly stopped working.

while looking around on the internet I am reading about complaints about it happening a lot with the ribbon cable, but i also replaced that (twice) and I also tried 3 different working screens(2 of them soft-oled and 1 service pack from samsung themselves)

is there anything I could still try or a common problem with this? I am having a hard time fixing this device and it feels like a waste to give up on it at this moment
