  • So Frustrated!! (Solved)

    This Issue has been solved. The problem was related to how the monitor was connected to the PC. See Final Postings.

    Thanks for all your help. 1 down, 2 to go.


    Hi All.
    Hope I am posting in the correct thread and that someone can point me in the right direction. My first CarPC install and I am so frusted. My touch screen monitor does not work after restarting the PC. I have to uninstall the drivers each time and sometimes it takes a few restarts before it works again. My PC Specs are below:

    WIN 7 PRO (all updates)
    Lilliput 669GL-70NP/C/T-HB-RV 7" HDMI, DVI, VGA High Brightness, 4 Wire Resistive Touch Screen Monitor (Tried all suggested drivers on this site)
    Zotac G41-ITX Wifi
    2 GIG Ram

    Does anyone have this same setup working properly?
    Should I try WINXP?
    Should I get another MB?

    I have search the Forum, but have not seen any issues related to my own. Hope someone can help. Thanks.

    How are you powering the touch side usb via powered hub or directly into mainboard usb port, what power supply are you using? some more details would help SNO

      Thanks.
      Directly into the mainboard. Using the M2-ATX 160W and Quick disconnect kit from the MP3car store.

        is your pc in a place where you can try to disconnect the t/s usb cable and reconnect it after startup? i am wondering if it is a issue with the usb cable and not the screen.

        also, where is the pc located, and how long is the usb extension going to the screen?


        and finally-- when it doesn't work, i assume you have a different way to control the mouse-- if you go into computer management, does the touch screen show up under the devices list? this is kind of redundant of the first question, as disconnecting and reconnecting should give you the windows 'device disconnected' and 'device reconnected' sounds if working correctly at the windows level.

        overall, i don't believe that it should be a OS or mainboard issue, because them you should be seeing other odd issues elsewhere in the setup--does windows act odd anywhere else, or do any of the mainboard usb ports have issues with other devices?

          The PC is easily accessible and I can try your suggestion.

          The PC is located under the rear seat of the Ford Explorer. The USB extension is six feet.

          The touch screen shows up as Touchscreen Controller(Universal) "can't remember eactly". When it does work, it works perfectly even after resuming from hibernation. Only when I restart the PC that I have a problem. I have a mouse/keyboard combo that I use otherwise.

          Windows does not act odd with any of the other USB devices.

                ^^ That link above, didn't work on my Win7 install. I ended up trying the xp drivers (I found them off a lilliput mini disc I had from an old touchscreen), and they worked perfectly. Who knew Win7 drivers didn't work with Win7. Maybe try the XP drivers as well, although not saying it will directly work with you/your system, but worth a try.

                Of course, I haven't re-started mine since using the drivers, always hibernating.

                    Those are the drivers I've used and never had a problem. I wonder why your Win7 system doesn't work with them, when my Win 7 Ultimate system does.

                      ok, that narrows it down a lot--

                      so the easiest thing to do would be to restart your pc so the issue shows up, and then see if the touch screen controller shows up under the device manager, if it does, check for a error code(clicking on it should say weather it is working properly, or cannot start for a reason). if ti shows up correctly, then it is one more step to being puzzled...

                      if it doesn't show up at all, then it's a start.

                      you can try to 'scan for hardware changes' and see if that picks it up.
                      if it still doesn't try resetting the usb cable.

                      if that doesn't work, do you have a different usb extension to try? it's unlikely it's bad, but always possible..

                        When I restart the PC, the touch screen controller shows up as either "universal" or " unknown". The error code I get is (43). I have tried all the suggestions mentioned exept changing the USB cable.

                        **** I just realized that I am not using any USB extensions to connect this device. This is how the Unit is connected:
                        HDMI coupler at touch screen, connected to 6 Ft. of HDMI cable, which is connected to another coupler, and then the cable that comes with the unit. The USB end is plugged directly into the PC.

                        Could this be the issue? How does everyone else do it?

                          I just want to make sure I'm getting this right.
                          when your having this issue, the screen itself works fine, but the touch portion is not functioning right?

                          If that's the case then your vga connection obviously isn't the issue and the problem lies in the USB.

                          Try unplugging all usb devices except for the touchscreen plug then try to replicate the problem.

                          You say that you have the monitor powered by the power supply, so if unplugging all other usb devices except the touchscreen fixes the problem then I would make the monitor have it's own power source from the battery and run a relay from the power supply that way it would still turn on when the power supply was on.

                          I don't know the power requirements for your setup, but I know from personal experience when I have more than 3 devices connected via USB (depending on the type of device) things go haywire and usually my touchscreen is the first to stop working due to not having enough power (I also have a m2atx).
                          Hope I could help.
                          Good luck.

                            I might have solved this problem, just waiting to see if the setup is stable before i say for sure.

                            I did try unplugging all other devices and that did not solve the problem.

                            As I mentioned before, I had the HDMI/USB cable combo that came with the unit connected directly to the motherboard with a HDMI extension setup from the connector to the monitor. I reversed this setup so that the HDMI/USB cable combo is connected directly to the monitor, and extensions are used to connect this cable to the PC. I have restarted and shut down the PC a few times without any problems.

                            I think the initial setup was causing problems with the USB signal. My initial question still stands as to how everyone else has their monitor connected?

                              my 669 is connected identical to how yours is now setup-- hdmi/usb cable directly off screen, to individual hdmi and usb extension cables that connect to pc.
