Evelin Ivanov, it is very tedious to open this type of device and secondly it has to be kept open and safe until you order the parts and it till it arrive

Since one section is damaged and has a lower voltage, the charging current exceeded the maximum and the built-in protection stopped charging and that is why you had fluctuations for pin 5. After eliminating the problem, the charging current does not exceed the maximum and charging starts and everything is fine.
