If everything above checks out, then unfortunately:Hi
I struggle to get the touch on the official touch 7" v1 DSI display to work.
It has worked before, but after a period stored away I upgraded from Pi3 to Pi 4 and now touch only works in top left corner (on the raspberry).
This is with no modification of the Pi image. I've tried 64-bit and 32-bit and also tested the old Pi3 used before with new OS image. Same results - only touch in the top left corner. Tried also to play with various dtoverlay settings found here in the forum but nothing helped.
And I have re-attached all the ribbon cables - twice.
Is it a hardware failure or is there a settings that I haven't found?
- The FT5406 controller or the touch digitizer glass has likely failed.
The symptom of only registering in one corner is a common sign of digitizer failure.
