    X646 / X644 LCD calibration or repair?

    I have a X644 with a slow response touchscreen and a X646 with "no centered" touchscreen defect.
    Is there a way to calibrate touch screen?
    What kind of procedure can we follow to solve these problems without changing all the LCD assemply?

    Thanks a lot

    I haven't seen that specific problem, I have had touch screens show the image reversed and upside down! Cute, huh? It was the small "inverter board" mounted under the cover to the left of the screen. Easy enough to replace, and it fixed the problem. If yours is under warranty I'd probably opt for that and the operator panel itself.

    Thanks for your help. No warranty. Machine are almost 4 years old.
    We never saw this problem too.
    So there's no calibration method.
    I will wche inverter then, if needed, change the lcd assembly.

    Thanks
