Repairing PS4 Controller

Bought a faulty PS4 DualShock controller off eBay which has a issue with some buttons not working.

Opened up the controller and after inspecting everything found a problem with the flex ribbon. Looks like some liquid damage to the controller and something has eaten away one of the pcb ribbon connectors.

The pin in the middle of the picture is completely missing!! Some of the other pins also look pretty suspect. This explains why only some of the keys are not working.

Looking around on the internet it seems to be a common problem with faulty ribbon flex. Luckily its cheap enough to replace.

Goes for $1-$2 on eBay. Ordered a replacement which should hopefully fix the problem.
