A detailed tutorial video on how to properly adjust the RF laser voltage on the Sega Saturn. It’s important to measure the RF voltage properly and set it to a working range rather than use the resistance method.
If you need a new laser for the sega saturn. Use the Optima-6S available here – http://s.click.aliexpress.com/e/qNZfqfY

This kind of stuff fascinates me… It's like a mechanic with a car but on a whole different level. I might be good with PCs, but this is a lot more intricate I feel.
Do you repair 3do lasers?
hey global garage I have a Sega Saturn model 2 and the problem I'm having is the checking disc format starts flashing when it reads the disc I replaced the laser and moved the pot but no luck so if you can please respond
mate , u are amazing , keepup
The technique there is sound, but one thing I would point out – when you need to do an adjustment to an existing laser, the laser has started to die. ie. It will output say 90 to 100% of its optimum value for the majority of its life (without adjustment) – but once it gets to that point where its output has dropped below say 80% (where it stops reading discs), increase of the voltage can bring the RF level back up (as you demonstrated), but the additional voltage (because its now higher than it is specced to get a proper level RF) coupled with the fact is is on its decay to providing no output whatsoever, means that it won't last long. You may get a few month (of intensive use out of it before the voltage needs increasing again). So its fine for getting up and running, but its not a long term solution – ideally you should just swap out the laser! Lots of people are doing this kind of thing and selling them on eBay – annoys the hell out of me lol.
Great video though, and as I say, the technique is sound – even if the DMM is a little inaccurate, its better than just adusting it and guessing etc. =D
