Ps4 controller charge ribon mare!

hi i have had a mare, i have replaced the left thunb stck on my jds 030 when i put the ribbon cable back in to the mother board the cores of the ribbon came out and probably touched, now after a new ribbon and usb port it still wont charge, i get 0.26 on the amp meter for probs a second then nothing the usb leds light uo orange and green on the pcb for about a second do you think the chip is u/s if so where is the best place to get one as they are about £13 off ebay uk and it probs not worth it.

idears please
