There is probably damage to the charging circuit. Sometimes it is one single component, some other times it is a whole bunch of them.
It can be repaired by someone with the right tools, experience, and access to spare parts.
However, if the problem resulted from liquid damage and that liquid damage is not addressed properly, there is a high risk of further deterioration of the components and traces on the board.
For one, cleaning must be done using a professional ultrasonic and proper cleaning agents.
Once done and the board is clean, the charging circuit can be assessed for damage and repaired.
If you feel like addressing it yourselves, you have to find the board number, the schematics, and follow the circuit using a multimeter. If you find the culprits, you can proceed to replace them using used parts from donor boards (sometimes necessary, in order for them to be programmed) or new spare parts when possible.
