I didn’t change anything. It just didn’t work one day to another
I tried to reboot, disassembling the HestiaPi to check the pins are right (despite it was working properly), trying to use xinput_calibrator to see if touch events are working… nothing seems to work
The display still works right, it changes when I change values from OH interface
Seems like another bad solder point
check with a multimeter continuity between the bottom of the PCB of the LCD pins and the tip of the corresponding pin from the top (shutdown and remove LCD first) for the Touch-related pins.
Can you temporarily insert the LCD on the Pi’s headers as far as it goes even if it does not stay level due to the relays? This is just to confirm the female header on the LCD is not damaged. If this doesn’t work, then somehow the LCD got damaged
No need to remove or modify any part. Simply lift the LCD from the top male header and sit it on the actual Pi’s male pins. The relays should block you from staying level but push it gently as far as it goes and try booting and check if touch events are registered.
That is really unfortunate
The few more incidents in the forum were the results from incorrect insertion of the pin header.
Currently we don’t even have spare LCDs. Someone on the forum has spotted and tested a non-asian supplier of the same LCD.
I would suggest as a final test to test it on another Pi if you have before you order. Forget about sensor and relays. Simply flash the same image and boot it on a Zero or 3 with the LCD properly inserted.
