Inky impression won't update

I have an inky impression and after a lot of trial I can’t get it to work at all. the e-ink seems dead.

I tried it when I first got it and it worked once then ever since I’ve got some dead pixel lines and no commands work.
I’ve tried reimagiing the pi and reinstalling the library.
I’ve been into raspi-config and ensured the settings are active but no joy

I always get:
Detected 7-Colour (UC8159)
/usr/local/lib/python3.7/dist-packages/inky/ UserWarning: Busy Wait: Timed out after 0.20s
warnings.warn(“Busy Wait: Timed out after {:0.2f}s”.format(time.time() - t_start))

pi@piink7:~/inky/examples $ sudo python3
