Bassquake Posted February 24, 2021 Report Share Posted February 24, 2021 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. Quote Link to comment Share on other sites More sharing options...
KaosEngineer Posted February 25, 2021 Report Share Posted February 25, 2021 I believe the one closest to the 73 marking on the flex pcb is the DVD laser pot. Edit: Is this a new laser assembly or the one originally installed in the drive? If a new assembly, did you remove the two (2) anti-static protection solder bridges on the side of the assembly? The two shiny dots to the right of the dark brown and tan colored flex cable connector in the picture below.

Bassquake Posted February 25, 2021 Author Report Share Posted February 25, 2021 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. 1 Quote Link to comment Share on other sites More sharing options...
