Alde touch screen not working

I've already replaced both fuses in the Alde itself. Any other suggestions about what to check?

The touch screen doesn't work both on 12v and 110v power.

    Just make sure the Alde is plugged in under the bench - although it may be a 12v issue.
    Check/change the fuse for the Alde circuit in the converter box.  If it is ok (I would just change it anyway), and still no go try this:
    If all your other 12v lights and appliances work, just turn the battery switch off - wait a few minutes, then turn it back on.  After a few minutes, try turning on the Alde. 
    If that does not work, remove the 12v wire located between the Alde 2 green fuse holders.  Then after a few minutes reinsert it.

    So I've got 12v to the unit itself and 5v out to the touch screen but the screen isn't lighting up at all. That to me seems to indicate that the screen is bad... Thoughts?

    Did you remove then reinsert the 12v Alde cable?

    Yes, removed the cable, waited 20 minutes plugged it back in. Also removed all power to the ALDE, waited 20 minutes. I've unplugged and plugged in both ends of the touch screen cable.

    This is from the Alde 3020 manual for a control panel failure:  

    Panel failure: Moisture is trapped in the control panel. Remove the Alde control panel from the vehicle and air it in a warm, dry place overnight.

    And:

    NOTICE
    Do not clamp or bind 12V cables or sensor cables together with 120V cables. It is preferable not to place the cables close to each other. If the cables are bundled, the risk of shutdown increases.

    It sounds like you have done all the usual things.  Is it possible there is a link or short in the wire to the control panel?

    I Found this:  A way to check the control panel is to “unplug the white DC power plug (between the two green fuses), then watch the control panel screen as you plug it back in.  If the screen briefly flashes from black to white, the screen is getting power, but the board in the panel is bad.

    Just ran out there and tested it and that's exactly what happened... Screen flashed and then nothing. So must be a bad board in the touch screen.

    Sure sounds like it.  Maybe that would be an easy thing to change out.  Is yours still under warranty?

    I don't think so. It's  2018. I'll call my dealer today and see if he can just ship me a new screen.

    A touch screen should literally last forever....
    So do you have any idea why the unit failed? Was there an event that might have damaged it? 
    Properly designed modern electronics should stand up to ambient voltage surges and certainly drops and live for years.
    All of the plugging in, waiting 20 minutes, changing fuses etc. etc. suggests a marginal design.
    Do you use a surge protector?
    Does anyone return failed electronics to nuCamp for failure analysis?
    There seem to be a significant number of Alde problems reported and troubleshot on this forum and seemingly an acceptance that this is normal. It's not.
    What is really great about the forum is that folks share their troubleshooting experience and knowledge but without field returns and failure analyses the Aldi design robustness will not improve.

    Agree, IMHO these ALDE units are not very good quality.
