Display has no back light but its coming on logo

I have a Yoga 7 16ARP8 laptop with a 360-degree hinge. I had to replace the display because it was broken. When I power it on, I can see the logo, but once the system loads, the backlight doesn’t come on. From a side view, the display appears very dim—almost like a negative image. Interestingly, the screen is clear in the BIOS, and it works fine with an external monitor. Has anyone experienced a similar issue?

It could possibly be a driver issue as the display works with the BIOS screen.

When connected to the external monitor what video driver shows up in the Device Manager?
