Hi everyone. I bought two ds4 after water. The largest traces of oxidation were under MCU and bluetooth module. After cleaning, I resolder the MCU, used hot air gun, waited until the balls under the MCU melted and gently shook the microcircuit with tweezers. I did these operations for two ds4. Thereafter the ds4 turned on and was detected by the PC. The only thing is that the l3 and Options buttons are constantly pressed.
I've checked the buttons for continnuity - the buttons are working fine. While writing this topic, I connected DS4 to the PC - the problem disappeared. after 10 seconds, the buttons again became constantly pressed. I will be glad to any advice. Thx.
