New build help: 4.3.3 blank LCD & port 3 wandering
Hi everyone.
I just finished my 4.3.3. I am a previously proud owner of the 4.2 but it finally bit the dust.
After initially booting with the Rpi (3), the LCD lit up but no text is discernable. Yes, I've played with the contrast dial...to no avail. Note that I have not installed the LEDs yet as I have not printed a case for it yet.
I can log into the HM's web server to view the data without issue.
Port 3 seems to be wandering all over the place (+/-400 degrees). Ports 1 and 2 seem to work fine.
Any suggestions on what to look for?
Also, the 5V converter seems to get really hot to the touch. Is that normal?
Thanks!
John
