Annoyed at myself for breaking the pad for a 2nd time repairing. Changed the port and then did this.
So originally changed the port. It didn't work, turns out you need a special ps5 pad usb c port. Should have checked first. No biggie, did it all again and put the right port on, and it works. Soldered down nicely.
The light button was sticking, top left, so I pulled it apart so I could clean the button (control was really grimey)
So I put it back together and put the two black screws in as im sure they held the touchpad. Now im thinking I was wrong and that it was two silver screws. Either way, im going to recheck but had to order a new one to fix the touchpad. At least the motherboard came off easy enough.
So im now £20 deep in a pad that should have been a nice quick and easy £3 port replacement.
I'm just annoyed at myself this should have a fairly easy task and I feel like ive cocked it up. At least it can still be repaired.
