    Hello.

    I'm new to this forum, so far it looks great, lot of useful threads. Thank you for this

    I hope someone can help me with my problem. On our machine Heidelberg speedmaster XL 75, touch screen at infeed and delivery won't work. Sometimes work, sometimes don't work.

    I alredy figure it out it's the problem with touch screen (borowed from another press and it worked ok). Before I order new touch screen I would like to try doing calibration on this touch screen, maybe than it will work.

    I looked on screen and didn't find any button for calibrate except 3 pin jumper on touch screen electronic (see picture bellow).

    Does anyone know how to calibrate this screen?

    Hi sir:

    1)Attached is there the steps for calibration Touch screen Display for Heidelberg Xl75
    You do not need to touch any pin jumper.

    2) However you must test the Leds H2-H5: H2- Green =On interface supply is ok. H3- green =Flashes quickly H4-Green=ON power supply good H5-Green=Inverter Voltage for back-light is o.k

    Thanks.

    Thought it is more complicated ;)

    I made a screen calibration, at the moment it works normal without problem. Hope it stays this way.

    Hi sir:

    You said before:

    "I made a screen calibration, at the moment it works normal without problem. Hope it stays this way"??

    If stopped working a day, Is NOT your fault, you must understand that everything has determined working life.

    Sorry for to order new touch display.

    Blessing.
