Thread: killed my Lilliput touch panel

depends you could have just fried a few small parts, a capacitor, or maybe a resistor, or a voltage regulator..

lok over the boards for any signs of burning and if ther is anything youj're in luck.. if not a micro-controller may be out..

by the wires that are soldered onto the board there is a small gold zener diode that probably blew. It's a 5volt zener


or you will have to buy a new touch controller

Thanks for the replies. I will check all those things out. I opened up my mouse to see if I could notice anything but the caps in there looked fine. The mouse is the least of my worries, when I get a chance, I will open up the screen and see if I can find anything.

Before doing custom wiring, ask someone if its right!! I wish more people asked for help, even if it sounds dumb, before doing something that they have no clue about. Electronics ALWAYS have the voltage used marked on the power supply unit and usually on the device itself.

I finally opened up the screen today and I could not find any signs of burning. I replaced the 5volt zener diode and it still does not find the touch pad. Should I replace the touch pad, anyone think that could be it? If its a micro-controller, is there anywhere I can buy the entire circuit board part?

Thanks for the link. I willl probably just buy the kit and replace it all. Is this the same touch kit thats in the Lilliput?

not sure, call and ask
