BDM-010 Doesn't turn on

[LORDCHECHE]

I replaced the joysticks in my controller and went to try it on my pc (i don't own a PS5). It was working fine but the sticks where going way to far to the corners soy y tried calibrating with steam. When i moved the stick it disconnected. Didn't want to turn on but eventually it did and same thing happened again. now it doesn't want to turn on at all. I checked and the soldering points are fine. could it be that a missing coupling cap is causing the problem?
