Help with LG BP50NB40

[MileHi2600]

Hi all, I've been using this drive for the past year. I have successfully ripped DVD, Blu-Ray, and UHD discs over the past year. I had been running DE_LG_BU40N_1.00.bin firmware from the flashing guide. From here: viewtopic.php?f=16&t=22896

A week ago, the drive started to not be able to read anything other than DVDs. I can put a Blu-Ray in the drive and it will just try to read the disc over and over (spinning up and spinning down). I tried reflashing with no success. I even installed the firmware update tool and put it back to the factory firmware. It still won't read a Blu-Ray disc (in Cyberlink Power DVD or MakeMKV). DVDs will play in PowerDVD fine and works in MakeMKV. I assume its related to encryption.

Did it just die from use? Is there something I can try to recover it?

Current info from MakeMKV 1.17.6 is attached.

DVD/CD disks are read with a red LED laser, while BD/UHD are read with a blue(ish) laser. If one dies, it doesn't stop the other from working, but it makes you think weirdness is going on. "It sort-of works!"

Thanks. I was assuming the same.

Thanks. I was assuming the same.

you can always try cleaning the lasers on the BU40N its easy just eject the tray

very gently clean lasers with a lint free cloth or qtip and alcohol and dry with another do this 2 times and do not let it air dry you must remove the residue with a dry one!
