I have assembled the kit I received from CrowdSupply and while my HestiaPi boots (I can access the web interface and SSH into the device) the LCD only ever lights up white (see image here). After reading a couple of similar topics on the forum, I have tried:
- Connecting the LCD directly to the Pi’s headers (not the PCB’s) - no change
- Refreshing the solder on the header pins - no change
- Using the same MicroSD card, connecting the LCD to another Raspberry Pi (model 1B, not connected to the PCB) - LCD works as expected
As shown in the image above I am powering the device using an AC adapter, although I got the same behavior when connected to my HVAC wiring.
Since my LCD is demonstrated to be working, I must have some other problem. How can I troubleshoot further?
