[SOLVED] Faulty Board? LCD only works directly connected to pi


#1

Just got my HestiaPi Touch ONE and I’m having an issue with the LCD. When plugged into the LCD connector it just displays a white screen: https://i.imgur.com/2WU7kbJ.png . When plugged directly into the Pi it works fine: https://i.imgur.com/VcbdNQ9.png . I buzzed out the LCD connector and all the pins are connected, but I don’t have the equipment to do a proper signal test. I would just run it like this, but it doesn’t fit into the case like this.

Please try this and get back to us.

Just beeped out from the top and indeed pin 22 is open. I’ll resolder and see if that fixes it.


#4

Yep, that fixed it. Thanks!

And as you can see it is one of the pins that do get used (not all Pi’s pins are used):


It is a very small fraction of the total units we made that passed continuity test but failed later but still this is annoying. Please accept our apologies and happy hacking now :slight_smile:
