Sega saturn power goes on ,CD wont spin
When I turn on the power to the Sega Saturn, the access light blinks and CD wont spin
A 32-bit fifth-generation video game console that was first released by Sega on November 22, 1994 in Japan, May 11, 1995 in North America and July 8, 1995 in Europe.
There is a real good video on youtube that will show you how to repair the CD.
Of course make sure that all cables are connected and in good working order. You could try to replace your cd drive for your sega by getting a console that has a working drive. Just checked on ebay.com and there are a few that are inexpensive. Keep those great consoles going:) good luck
Updated this old answer due to somebody having some issues with the original answer.
I have a saturn and mine would turn on to the main screen, but would not spin the disc. I noticed if the door was pushed down just a little bit more, it would then spin the cd. I took the saturn apart and just ajusted the arm for opening the lid. it worked fine after that. It has been a few years since I have done it, so I really don't remember the details, but there may be a tutorial somewhere if you google it.
