Post by: kisaku on 09/03/2017, 11:21 AM
Hello everyone i have a big problem with a nec laseractive.
Hucards work fine, the problem is with cd and LD.

Then 2 things I will do first.

1. Use water to clean the laser lens.
2. If still no luck,  try to adjust the pot on the laser lens just a little bit (clockwise)  to see if it helps

The pot is located on the laser lens.  It is a tiny pot on top of the ribbon cable and below the white circle of the lens
