LG H10 N doesn't find medias

Hi all,

2 month ago I bought this H10N burner. First I did not realize it but now
it doesnt find DVD medias (especialy DVD Ram).
Explorer is blocking now and continues working after I open the tray again ?!

It means, I have to open the tray twice or more times and then with good luck it finds the DVD’s !!!

My other 4763 never has given me such problems.
Any advices ??

My H10N does the same thing, firmware JL11, but it’s very random. Ejecting the disc and refreshing Explorer usually solves it.

Forgot to mention: I am getting black screens + hangers.
And it’s quite often - no solution so far ???
