CFAG320240CX-TFH-T-TS touch screen problem


New member
Hi, I'm trying to use CFAG320240CX-TFH-T-TS display. I have no problem with display section, but when I insert touch screen connector, display become black. I read this is a common problem for other user but I didn't find the right solution. I have already tryed to add an R-C filter on touch screen signals but without results.
I examined touch screen signal with oscilloscope and I found great noise (added after DISPON command)
but I'm no able to remove this.

Some ideas?

Thanks you.
