Apple Cinema Display 30" - Detected but not powering on

Hi there,
I just purchased two Apple Cinema Displays - both "30". I checked each display before I bought it -- worked perfectly. However, after driving home with the displays and plugging each into my MBP M1 via a separate USB-C to Dual DVI adapter, one display works perfectly (and is detected as Cinema HD), but the other display is showing just a black screen, and the LED power indicator is also dark, and is detected, but not as a Cinema HD display, but as "Display". Any ideas on what I should do?
This is what the System Information shows:
