    aspire Z3801

    Hi,
    aspire touch all in one board DA0QK3MB6E0
    I have two boards, the first shows the screen divided into three orizontal parts
    the second have all usb ports not working.
    This occurs with the same memory and cpu.
    In the second board I detect a short on a usb port related to a data line but after replaced D18 the short disappears but nothing changes.
    The pch is an H61 SLJ4B , both boards are UMA and I haven't find any schematic . (I replace both bios and EC firmware)
    Thanks

    The PCH HM chip may be defective if the USB data and clock pins are intact and + 5V is smooth. You can try reball the VGA chip if the RAM is correct.

      Thanks,
      I am not familiar with this type of card, i only fix laptops, so the video controller is inside the HM61
