Hello, I repaired this controller by removing the battery and with an external source I put 2.5V to see if the charging IC or any other components got hot, it didn't get hot at all, I put the battery back in, which was in perfect condition and the controller was off, I connected it to the play and it worked, I disconnected it and it disconnected, so the controller was in perfect condition, I don't know if putting an external charge in it did something to the charging IC, but it started to work perfectly .
