    I found a pdf on this site about alarm 401 from congchipham in 2008.

    With that pdf I followed the steps.

    Was a problem with the JX5 pins (they go in my machine to X32 on main board)
    bad contact but now is working again.

    Thx for putting that pdf on the internet.


    kind regards pedro
