    Sony Vaio VGN-FZ21Z PCG-391m no image after replacing the graphics chip

    After replacing the G86-770-A2 and G86-750-a2 chip from sony VGN-FZ21Z image after you log in to Windows displays only on an external monitor. Safe mode is displayed normally.
    Solution:
    Uninstall the graphics drivers from the device manager. After reboot, install the original drivers from sony web page and everything will return to normal.
