Title: Turbografx cd Test
Post by: megamanmaniac425 on July 24, 2015, 03:25:49 PM: Is there anyway to test out a TG-CD without the system card ? It turns on and cleaned up and reapplyed grease to the rail so its not jammed. I just want to know if i can test it and see if it spins before buying the system card :). Any help would be great.

It should play standard audio CD's, see if it plays smoothly, doesn't make noises, doesn't skip tracks. Listen to the sound of the drive itself, as well as audio out (headphone jack/RCA OUT).

This doesn't guarantee CD-ROM drive is operating, but at least it may bolster your faith to get a system card proper.

Put an audio CD in the drive and press the play button on the drive itself.

Is it possible that it wont spin if the laser itself isnt working ? And if so where can i get a replacement if anyone knows ?

Being 1.0, 2.0, 2.1 and US 2.0

The ribbon cables are also put back in right. Will bad capacitors cause it not to spin ? I cant find any faulty caps but i may try to replace them as well if its a possibility.
