I have had a Spark Photon for about 1 month now and have seen a number of issues with the screen. Periodically, the screen shows all white on start up. About 50% of the time, a power cycle of both the Pi and Spark (spark is powered by via USB from the Pi) will resolve this. However, last night after a reboot, the screen started “missing” parts of the display, showing (apparently) random colors instead of what was supposed to be there. This morning, I realized the screen has stopped updating altogether (idle timer is not changing and display incorrectly reports “Beer Constant” mode, should be “Fridge Constant” mode.) Picture attached is from this morning, still showing artifacts in display. Notice the pink square at top right and the missing digit in “room temp”. Spark seems to be working fine otherwise; the Pi script is running and webpage and graph are up to date and reporting temperature fluctuations.
One week ago, when researching the white screen, I ran the updater.py script and everything was up to date. Actually, it shipped with the most recent version of firmware.
Also, possibly related, when connecting the micro-usb cable to the Photon, it feels like the entire Photon board moves a little bit top to bottom. Is this expected?
Is this a bad screen or is there something else I can check on my end?
