I bought a defective controller and replaced the battery and the flex cable to the charging socket. Now when I connect it to the power the yellow light does not flash, only once briefly when I have completely dismantled it and had removed the charging book and put it back in. Since I bought the right spare parts, it can only be due to the charging socket, right? I've already connected it to the laptop and PS4, but it doesn't load anywhere. I would be excited to receive answers.
Have you connected and checked everything correctly?
Otherwise it can really only be due to the socket
Yes I think so. Would you recommend that I buy a new socket or can you repair it otherwise.
Buy a new one
