Flooded xiaomi redmi note 4 - The phone does not charge when it is turned on

Hello, sorry if I chose the wrong section.
To the point, I have a xiaomi redmi note 4 phone, it was shattered (not important) but after that it fell into the water and after this incident the display spilled (maybe it did not spill, but there were stripes on it, it is normally readable in full), but works, but the problem appears when charging, when the phone is turned on, it does not detect the charger or connection to the computer, but when I turn off the phone, it behaves like a discharged one, detects the charger, the charging icon appears and the process continues, while after turning on the phone again it stops detecting the charger, can it be saved somehow?

You had to start with this, since the phone is flooded: https://www.elektroda.pl/rtvforum/topic1273413.html
In addition, it is still after the fall, so it's a difficult matter. it would fit to go to the website and ask for a diagnosis.

I mean, the strikte phone works, it cracked in the morning and worked normally, all functions, it drowned in the evening ... only the only drawback that he has left is charging, how much can it cost? Thank you very much

Then you have to ask local services because everyone has their own prices.

I have the same problem with the flooded xiaomi mi note 10. There is still a chance to find out if the phone was repaired?
