Display greyed out, Busy Wait: Held high

Hello, I hope you are doing fine :)
Recently I purchased 2 Pimoroni e-paper 7’'. I’m currently using an RPI 4B.The one is working as expected but the other one not. It is greyed out and displays the following error (when I run clear.py or image.py):

diffy@raspberrypi:~/Pimoroni/inky/examples/7color $ python3 clear.py
Detected 7-Colour 800x480 (AC073TC1A)
/usr/local/lib/python3.9/dist-packages/inky/inky_ac073tc1a.py:273: UserWarning: Busy Wait: Held high. Waiting for 1.00s
warnings.warn(“Busy Wait: Held high. Waiting for {:0.2f}s”.format(timeout))
/usr/local/lib/python3.9/dist-packages/inky/inky_ac073tc1a.py:273: UserWarning: Busy Wait: Held high. Waiting for 0.40s
warnings.warn(“Busy Wait: Held high. Waiting for {:0.2f}s”.format(timeout))

warnings.warn(“Busy Wait: Held high. Waiting for {:0.2f}s”.format(timeout))

Could you please tell me if it’s faulty or not? I tried clearing, setting a few different images but still didn’t have any luck.

Looking forward to hearing from you.

PS: Forgive me if i have done anything wrong. It’s my first post. :)

I’m posting that here, as a reply because I couldn’t on my main post.

I assume you already checked if you plugged in the display correctly and you did a complete powerdown and reboot.

If so, I would suggest that you write to support and ask for a replacement. The fact that you have two of these displays and one is working fine is a strong argument that the problem is not caused by your setup.

Hello and thanks for your reply.

Yes of course I checked everything. And as you can see on my last reply with the screenshot it states that the screen is detected “Detected 7-Colour 800x480 (AC073TC1A)”. It recognizes the screen but doesn’t display anything, other than grey pixels, nor it draws anything new. The screen is stuck in that image condition I posted on my first post.
