I too am having the same issue. The most I can get to display on the screen is either having it go entirely red or entirely white. I've used both the Python and C tests supplied by Waveshare, and multiple different tests:
epd_7in5bc_test.py
epd_7in5b_HD_test.py
epd_7in5b_V2_test.py
epd_7in5_HD_test.py
epd_7in5_test.py
epd_7in5_V2_test.py
Been hammering my head at this for awhile... even tried removing the extension board/white ribbon cable and still same issues. I've used both the HAT and no HAT with same results.
from e-paper.
Exactly same here, I did many tests but none of them drew anything on the screen...
