. Before you get started lets get a reading of exactly where the adjustment is set. Using your voltmeter in the
Ohms reading setting put 1 lead at the bottom of the adjustment and the other in the upper left corner (see
previous photo). Write this reading down so you can go back to it if needed. Using a very small screwdriver
carefully turn the adjustment to the right about 1 degree. Take a measurement again. You will then have to put
everything back together and try it. If it does not work you can keep adjusting it over and over until it works.
I have found that the CD adjustment can be anywhere between 950-1200 ohms and the DVD can be
between 650-1000 ohms. This can be a very time consuming process but it will work for some of you. The key
is to be patient and careful. If you get in a hurry you may pass the point where it works or you may damage
something taking it apart.
OPTIONAL- If you don't have an ohm meter you may also just turn the adjustment about 1 degree at a time.
Make sure to mark your starting point with a felt tip pen.
After you are completely done doing this alignment make sure to use the grease mentioned at the beginning or
something similar to grease up the rods that the laser slides on. I'm sure they are dry after the laser has been slid
on and off so many times. This will make sure that it can travel freely after it is reassembled.
