Ha....strangest thing. I had the same problem. And experimented a bit. I replaced the WiFi cable and the only issues were the micro ribbon cables. Which side is up and which is down. I was getting the repeating chime on start and decided to flip the WiFi cable where it went into the screen at the top by the camera. This fixed it. If these cables (or any of the cables are flipped this causes problems that are hard to track. So if you mucked with cables or disconnected them, this might be your problem. It appears that the side with the copper strips generally face up. But before you disconnect, take close accurate pictures as you remove them.
