BU40N Failed to open disc

Post by uzerkool »

I have a BU40N (v1.00, from a known supplier on the forums) that has worked perfectly in the past but now says failed to open disc for all of the various discs that I have tried (a couple different regular Blu-ray and UHD disc). The drive recognizes the discs, it shows the title and the protection type but when I try to access the disc I get the following:
