    Need help on fixing lilliput usb

    First off, I am a total idiot.

    Now that is out of the way, I was rewiring some stuff and accidently wired
    12v ignition to the 5v output of the m1-atx power supply (thank got it was fused 12v) That was an expensive mistake. Fried my m10k, 2 usb hubs, hard drive, and my 7" lilliput's touchscreen usb. The m1-atx power supply was somehow unharmed! I got it all back together and now the monitor works fine but when I plug the lilliput's usb cable to the pc it makes all the usb devices malfunction, like they were unplugged. So how would I go about fixing only the usb portion of the lilliput? Do I have to replace the whole touchscreen or is there a controller inside for it?

    There is a controller inside. Normally, Touch Screen controller is separated from the main PCB.

    The problem comes from a bad pinout of the 4 wires , or from the TS controller itself.

    We have to know the model of lilliput's screen you have.

    Normally, if you have to change the TS controller, you will be able to by it here :

    PS : Is your mothreboard OK or DIED ?

    maybe i'm confused... you wired an 12v device to a 5v wire and destroyed ALL that? How is that possible? If anything the lilli woulda not powered on at all.


    EDIT
    NM, 12 volt ignition not 12v lilli. Yea you are an idiot

    In order to fix the touchscreen ur gonna have to open the lilli and find the touchscreen controller. Its not hard to find... its where the usb cord ends. You unbolt it from the pcb and replace it. 50 bucks for digitalww

    I took the lilli apart tonight and it looks like I might be able to fix it. There is a zenir diode across the 5v usb input and ground on the ts controller board and it is bad, which shorted the 5v input to ground. That is why my usb stuff dies when I plug it into the pc. I am going to remove the shorted zenir and see what happens.

    I want to know how you got the car's IGN line going into the M1ATX 5v output? Through a molex connector? The fan connector?
    Is there a fan connector on the M1ATX?
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    I had the 5v output from the m1-atx wired up to go to the front of the car to run a powered usb hub. When I was unplugging a few wires to repin a conector, I accidently put the 12v ign feed going to the m1-atx into the 5v output pin from the m1-atx. [smoke now] [/smoke now]

    ITS FIXED!!!

    It looks like they put the zenir in there to protect the usb controller from overvoltage and it saved my touchscreen! I just removed the zenir and it works! I am not too worried about having extra voltage protection on it now since I will be a lot more carefull in the future. I could probably replace it with another zenir but there are no markings on it I can see anymore and it is not worth the headache.

    You sure that's a good idea, considering your recent history?

    It's not worth saving a buck parts and destroy a 50 bucks controller.
    Replace it.
