    Hi Jorge;

    This problem is indicative the thousands of transistor inside from LCD, are faulty, you Will need to replace the LCD Display.

    However, you must Tight very well the ribbon or flat cables, and see if there are o.k, or are Dirty, loose, or broken, or Corroded and clean.

    See if the Display are Battery, and measure the Voltage, and see if there are o.k , otherwise replace with the same characteristic.

    Hi Jorge,
    As Chock explained, the LCD panel should be replaced. I did it on the same control panel one months ago. Send me an email to make a quotation for you. It's better to send it to Denmark for repairing.

    It could be just the back light that is faulty, or inverter. Check if there are 2 white wires to the side of the screen and a little pub, try changing these

    Hi Andy, Thanks for the picture I am waiting for the machine to finish the job so I can open the control panel to see what display is and if it looks like the photo.
    I will replay when I open that.
    Thanks.

    Dear Jorge,

    Backlight CCFLamp(s) and/or the CCFL High Voltage inverter(shown on the Andy's picture) should be replaced.

    Regards,
    Oleg T.
