    acer aspire one DA0ZE6MB6E0 no display

    acer aspire one DA0ZE6MB6E0 no display.

    All voltages ok

    All power good signals ok

    Replaced ram, DDR ram reset ok.

    No caps lock, Num lock lighting and no display to external monitor

    Flashed bios.

    Reflow processor.

    Same issue.No display.Any technical idea would be highly appreciated.

    If you have a oscilloscope,measure communication on SMBUS clock/data for Ram. If there is only one pulse on oscilloscope,very likely a damaged CPU or ram requirement is not completely fullfilled.You should have 3-4 pulses on DSO if ram is properly communicated.
