Replacement screen cant work after reboot

I have a very interesting issue. I have a pixel 7 pro. My screen touch is not working and bought a replacement unit. When I change the screen it was working fine. Touch and fingerprint sensor all working fine, can on and off also. However, once i restart the phone, the screen stops working. In order for the screen to work again. I need to remove and reconnect the screen connector (when the phone is on) and the screen will work perfectly again. However once i reboot, the same issue happens.

So, i tried the few solutions and still the same Issues.

1. Factory reset
2. Disconnect the battery and reconnect
3. update android to latest version.

So now the only way to keep the phone working is not to reboot which is scary. Any suggestions?
