    Mxm7570 keyboard wrong characters

    Iím having and issue with a mxm7570. Initially the op panel would go black randomly. I tried the firmware update without success. I ordered a new op panel screen. I replaced the screen and that issue of black was resolved. 3 weeks later I now have an issue with the keyboard. When you press any key it will type a sequence of random characters. Iím thinking the issue maybe with the converter underneath the keyboard.
    many ideas?

    Sounds like the display got hit with disinfectant. Have you tried to clean key contacts?

    I have had this happen a few times. Reseat the connectors if you haven't already done so. If that doesn't work, then you can either replace the little board that is on the keyboard or replace the keyboard.

    Good luck.

    I have seen this happen. Replacing the keyboard fixed it.
