Hi KaosEngineer. It's the original assembly in the drive. Thanks for pointing out which is dvd laser.
I saw that video. It could do with proper closeup! I figured out it's the 2 bottom pins of the pot you put ohmmeter on.
On mine:
73 (dvd) = 2.17
77 (cd) = 1.00
I set the DVD one to 2.10 and it can read DVDs fine now! CD doesn't work yet, will adjust at some point.
I have a Samsung SDG-605 and need to tweak the pots for laser as it's having difficulty reading. Have snapped a pic and wondering if anyone knows which is for the CD laser and which is the DVD one?
I didn't want to have to keep taking drive out to tweak them individually and test and nauseum!
Thanks.
