    Display not working MPC2550

    Hi!

    I went on a MPC2550 this morning and the display dident work. Well it works but theres no text on the display just light form it. I change the Card under the display but no results.
    I also checked the Powersuply for brokend fuses but they are OK...

    Im out if ides. The machine is 2 weeks old.

    Quick answer is appreciated

      When you say "Card", do you mean the LCD display or the touchscreen or both? If you have access to another MPC2550, swap out the entire control panel to test. If it works then swap individual boards out until you find the offending one. If another control panel has the same symptoms then you know you need to look at the controller/bicu.

          Thx for quick answer.
