i have 4 lasers i am switching back and forth between 3 cubes. i adjust them around 200 and some work and some dont. i have a brand new laser and it is the worst one out of all of them. which direction should i be going? it would stand to reason that a higher number would incresae brightness of the laser. it seems however that as soon as i get much over 220 the lasers wont read anything. did i get a bad laser? why are they so different when booting the exact same disc? is there a way to adjust these with an oscilliscope? any advise would be great. i would like to verify this "new" laser is bad before ordering another one.
