Replaced screen and charge (usb) board. Now USB is not working.
I have a nexus 7 2nd gen that had a cracked screen and worn usb jack thanks to my son. Anyway, I replaced the screen with a complete ebay piece and purchased a used usb board on eBay for it and now it will not charge at all via usb and the usb connection to my pc is not working. The tablet will only charge on the wireless charging pad now.
Thinking it was a bad board, the seller sent me another board and it's still doing the same thing. I also replaced the ribbon cable from the usb board to motherboard hoping that may have been damaged but still no luck. The only "testing" I have done was verify that I have 5v coming out of the usb jack, other than that I am lost. Any advice on what to do next? Thanks.
Is this a good question?
