Display dead, no PC connection anymore :(


Recommended Posts

Posted · Display dead, no PC connection anymore :(

Hello,

I'm from Germany so please forgive me my crappy English.

Today I wanted to change the 5V hotend fan as I unfortunately noticed my UM2 shutting down.

After a second it restarted but the display stays dark and there's no connection to PC possible anymore.

The White LED Lights are still working. The PSU delivers 23V. The yellow LED indicator is on.

Has anyone an idea or suggestion what to do or check? A new board is soooo expensive. 😞

Greetings from Germany

    Did you just worked on the print head or also on the bottom of the printer? 

    You have probably shortened something during your work. So please ALWAYS turn off the printer and disconnect the power before you start working on it.

     

    If you opened the cover on the bottom then maybe a connector is not in place anymore.

    Hi @Disobeyed,

     

    Sorry to hear that..

     

    When you said white led, are you talking about the light strip inside the printer?

    So to the amber light, is this the one on the main PCB?

    There is "several" LED lights, so we need to know the correct one.

    There is three "amber/red" lights, two yellow and one green LED on the main PCB.

     

    Here is the PCB layout with associated components:

    Please indicate here.

     

    Thanks

    Torgeir

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
