I have a Turbografx CD drive that usually works just fine. The gears move freely and it reads very well. However, every now and again when I hit play I will hear the lens jump up and down over and over again trying to read the disc. What is weird is if I simply just turn off the power to my system and turn it back on again then the CD drive reads just fine again. Anyone else ever had this problem?
Give this thread a read.
