    Hi sir:

    Most of the times happen this:

    1) the dirty is the worst enemy of electronic devices, please clean very well all Edge connector from boards key, and look for dry +colder joint solder, look for loose wires, or connectors., or key in short-circuit, that will be put all the keys in Short-circuit, test easy with some DMM in Continuity.

    2) Or the board is faulty, replace or repair.

    Blessing

    Test the power supply for PUD,
    2) look for loose wires in the connector.
    3) flat cable or ribbon cables faulty, or dirty, or loose.
    4) interchange the cables and electronic board, and see if the problem fix it.
    5) clean very well the connectors, from dust, corrosion, etc.

    Blessing
