    I believe I have a failed SBC (touchscreen computer) in my T-112 surface. I have some questions about replacing it.

    1) Based on the attached document I found in another thread, there appear to have been three different SBCs used in the T series. I believe I have the “Fujitsu SBC – 004-111 – AE8214” in my surface. Would I have to replace it with the same SBC, or would any of the three models work?

    2) Does anyone know if the T-80 and T-112 used the same SBCs? I’m guessing the answer is yes since the attached document calls out different SBC models for the R72, but it would be great to have confirmation of this.

    3) As far as I know these SBCs are no longer available from Allen & Heath. These SBC units look like off-the-shelf computers to me, but so far I haven’t found the right search terms to find anything like these outside of the Allen & Heath world. Does anyone know what the generic name for these computers are that I might be able to pull up in a Google search (type of computer or processor model or anything)? Or better yet, does anyone know where/how to find these computers outside of Allen & Heath?

    By the way, the troubleshooting I’ve done that makes me think the SBC is bad:
    * The CMOS battery has been replaced and is good
    * There is 24V power to the SBC (actually 25.6V when not under load)
    * When powered on the touchscreen is all white. I’ve tried attaching an external monitor to the VGA port and I get absolutely nothing on it.

    I’m open to other troubleshooting steps, but I work with several iLive systems so sooner or later I’m going to need the above SBC info even if not for this surface.

    Thanks.

    any of the three will work, I guess

    Did you ever asked?

    Update: based on posts I had seen I didn’t think the SBCs were still available. But Full Compass finally got back to me and my SBC is still available for a bit over $1200.

    I’d still like to know if anyone knows the commercial part numbers for these SBCs, as they still don’t look exclusive to Allen & Heath to me.

    Hi there,
    When the cmos battery goes flat you end up with a white screen on boot up. If you have changed the back up battery you will still have just a white screen at boot up. The touch screen computer has reverted back to its factory setting. You have to reset the screen resolution and the VGA output port by entering the bios mode of the computer at boot up. I had to do this to my own T-112 and T-80 after the touchscreen just stayed white.

    Hi Kevin:
    Thanks for posting this info. I also Have a T-112 and T-80. Do you have any documentation explaining how to get in to BIOS mode on the T series?

    -thanks, Mark

    Hi Mark,

    First you need to connect up an external monitor and also a USB keyboard to select the various settings once you get into the BIOS.

    Power up your desk and hold down the DELETE key, there are different instructions to follow depending on the type of SBC you have. I will attempt to attach the instructions here but if that doesn’t work I will have to email them to you. You will see the instructions are for the factory guys to set up a brand new SBC out of the box, so some of the steps will not be required as you have an installed device already. Let me know how you get on.
