Console Repair/Mod Center
I have acquired a recapped PC Engine Duo, but when I got it the CD spindle did not spin up sufficiently to make the disk spin and nothing could be read. I could see the laser head moving up and down, so I thought that the motors may be bad. I bought a new disk laser assembly : https://www.ebay.com/itm/182710804499 to replace the old one.
When I got the new assembly today, I found two problems with it. First, the wiring was different but the same points are present. The second issue is much more of a problem. Simply put, the spindle platter on which the disc sits is below the laser head assembly. If you put a disc on the platter, half of the disc will rest on the laser assembly plastic. I don't know how this was supposed to work with anything, but I do notice that there is a silver shaft that has room to move the platter upward on this assembly whereas on the old assembly the shaft was about as high as it could get.
I really believe that the disc shaft motor on my old assembly is not working anymore. I applied ~3v to it and the spindle did not move where it did move on my new assembly. The disc spindle motor and drive sled motor are powered off the came cable and BA6290A, and the drive sled works fine. I found out how to adjust the height of the platter relative to the shaft, so I should know more once I replace the power cable from the assembly.
