lilliput eby701 not recognizing the touch...

**ph7ryan** · 08-26-2009, 08:00 PM

Hi,

I just received my lilliput eby701, and immediately transfered it over to the double din frame by bybyte. I then plugged it into VGA, and powered it up, and visually it works great. Then I plugged in the usb and it noticed the touchscreen, and since I have touchkit installed already, it said that the hardware has successfully been installed. I then go to touchkit to click the 4 point calibration and it doesn't recognize when I am touching the flashing target. The bar at the bottom just fills up completely and says that the calibration was not completed. I have reconnected the ribbon cable from the overlay to the circuit board many times. is there a setup step that I am missing. The screen is brand new. Thanks for any help.

Ryan

Make sure the screen isn't pressing against the frame.

i have already removed the screen itself from the frame, and tried pressing it while holding the lcd in the air....still nothing

Could just have been broken during the installation to the bybyte frame. Didn't take much for me to break one when I did my transfer. Did it work before you transferred it?

How you calibrate it? It must be long pressing (till it give next one) of each flashing target. And it must give audible feedback for each pressing.

i am pretty sure that I figured out the issue...When i closely examined the ribbon cable for the panel, I noticed that all of the pins were cracked from their leads. I tried to solder them back on, but accidentally soldered 2 of the pins together...so I decided to just use the leads themselves, and melt the plastic off of the ribbon at the tips enough to expose some metal. The ribbon would not stay into place, so I realized that the plastic part the pins are connected to is essential for the cable to stay in place. Currently I am waiting for the glue to dry in order to have a solid connection from the ribbon to the board. This screen has become a financial nightmare (1 doa, one wrong size so i cracked it, and now one with messed up ribbon) so I have decided that I am doing whatever it takes to make it work...down to if I have to solder the leads directly to the board I will...

so for those wondering, I successfully soldered leads from the ribbon cable to the pins on the back of the ribbon holder...IT WORKED!...no damage at all either...the only problem is that it is extremely delicate and I need to be careful or it easily breaks its connection...
