PanelDue 5i touch not working
-
Hello,
I've started 2 days ago with the installation of my duet maestro and everyone is going swimmingly.
yesterday I did install the paneldue 5i, it works perfectly and everything is set up to a minimum before a firmware update that I want to do the next day.The next day comes around, I install the paneldue in a recommended model to hold it and start the controller. Everything seems fine. Except one thing, the touch doesn't work.
The screen itself works perfectly and I see everything from the webinterface updating as it should.
I tried updating the firmware, That worked, but now I'm stuck at the touch calibration screen, without a working touch element. I'm stuck.Any input on it? I suspect a problem on the flexible pcb element.
update: I did find a small crack on the right bottom corner of the tft screen. could this be the issue?
-
I haven't seen the schematic but I suspect the touch interface is the smallest 4 conductor flat flex is for the touch. I'd be surprised if the crack in the glass outside the touch area would affect use. Maybe see if you can get a close up of the flex?
-
I got a multimeter to those 4 points but the solder on them is still fine.
Are there any values I have to look for to confirm function? -
Not sure what the nominal value would be, but it might change if you tap the screen?
-
they do change in the mA (Edit: mV not mA) value, so it's prossibly not a connector issue to the rest of the flexible pcb, but on the rest of the controller on the flexible pcb itself or the pcb in general.

I've searched a bit through some threads and I came up to a thread that also mentioned a small cracked portion on the screen: https://forum.duet3d.com/topic/7345/paneldue-5i-touch-location-is-off-towards-the-right/12?_=1583190483896
That's possibly the reason, I'm not sure though.
I'm probably gonna send it back for waranty now. -
Did you take it out of the housing? Perhaps the housing was pressing on the screen.
