I've the same problem with my controller that came with my PS4, I haven't used it much in the last year or so, but it was practically new, kept it in my ps4 bag, no hits or any damages, I tried to used it but the up and right arrows won't respond, I disassembled my controller to check it out, everything on the motherboard seemed ok, no damages, but still I cleaned it with qtips and some alcohol, but still not working, it is a v.1 controller and don't have the money to get a new one, can anybody help me please?
