This looks like a case of "dirty CD/DVD recorder". Try to open it and
gently clean the lens with cotton and some alcohol for about 30 secs,
then with a dry tissue or peace of cotton "dry" it. It should work now,
if this doesn't work, then probably the device "expired". IMO LG burners
are the best they're, at least in my Country Bolivia.
Good luck.
Cheers.
