Bravia TV are a bit tricky as all the boards are co dependent but I would try doing a firmware update with a USB drive. You should be able to locate that on the Sony Support page and walks you through creating the usb with that file and the steps to do on the TV. AND also give the usb a long while to compete it's thing. I once was impatient and had given up on it, left for lunch and it was able to complete the process and came up.
