This is what I found: I disconnect the cable for the digitizer (touch screen), and the LCD *will* work. Connect mouse with OST cable, and you can control your Xperia again. So issue looks like the digitizer... I think the OS cant cope with the firmware of the digitizer, and the digitizer firmware must be upgraded. I had this one time before, and I solved it with a firmware update (PC companion - Software repair, don't need a working LCD to do this, or disconnect the digitizer, connect an USB mouse with the OST cable, and upgrade firmware from android). Anyways, in this last case, firmware did not work for me. Any ideas are welcome. By the way, if you can find the youtube instructions... Please post!
