iPad Pro 11" 2022 does not charge. The connector has been replaced.

The iPad periodically did not charge and stopped charging at all. I disassembled it and charged the internal battery. The iPad turned on and works fine except for charging and data transfer via cable. I replaced the connector. I examined the old one carefully and I do not rule out that the contacts on it were damaged and shorted out. With the new connector, the iPad also does not want to charge. I checked the USB-C tester and I see that the VBUS line is faulty, but I do not have a diagram to trace the path of this line and decide on further repairs.

Voltage on the port is 5V, current fluctuates around 0.2A.

Perhaps someone has a diagram of at least previous models to suggest where to look for the problem? Can you advise anything?

Thanks!
