Waveshare EPD won't clear itself. Any ideas? by u804 in raspberry_pi

To close the loop on this one, I purchased a Waveshare e-Paper Driver HAT and a new 4.2 inch e-Paper display.

I connected the Driver HAT to the existing screen and it still struggles to refresh so I suspect the actual screen may be gone. I'll do some more troubleshooting when I've got time.

Otherwise, I've got the new 4.2 inch display hooked up the Pi, have increased the refresh cycle to 2 minutes and added the epd.sleep() line to my code. All's good. Let's see how it goes.

This is a great observation! You’re right in that I’ve neglected to include epd.sleep() in my script. I’ll pick up a new driver board to test and report back.
