If your device is not recognized by iTunes but works well otherwise, then it is probably an issue with Tristar. You will need to remove it again, check all the pads and surrounding components and install a new one.

Sorry for commenting on the old reply.
My ipad pro 12.94th gen is showing similar symptoms. It can be charged, but it is not detected by PC at all. (I tried replacing the dock flex cable by disassembling the ipad, but the symptoms didn't change. I used every means such as replacing usb cable/PC.)
Is this also likely to be a problem with USB ic like tristar? (in ipad pro, Probably the CD3217B12 chip is USB ic)

Check the mail voltage rails for shorts. (PP_VCC_MAIN, PP_BATT_VCC, etc.) does any part of the phone get hot?
