Also the light is supposedly "invisable" so instruments may be needed to see it.

have you made sure the little tab on the lower right front of the lid is still there...the one that goes into the interrupter circuit within the CD32 to indicate the lid is closed and hence try to read a disc?


Is there a picture of this? I am not sure, but I can absolutely hear no mechanical noise, or whirring coming from the CD drive. My PS1, SEGA Dreamcast, Saturn, they all make noticeable read-access noises.
Kind Regards,

I was just thinking also...does the CD access light work in ANY way at all? (That may give some direction help to diagnose the problem)

*EDIT* I just found this quote of yours... "The system boots up, but just like before, the CD does not spin at all. The CD access light does not lit up."

So...without knowing exactly how everything should work...I would say it's possible the drive isn't actually getting any signals to "do anything"...and that's why it isn't "doing anything".

This.... ( apologies for the upside down photo :) )

Goes into this...

And then through the interruptor module within the casing...

Hi
to see if the signal is getting to the cd module, open the lid, an watch the laser lens as you power on it should vibrate immeditely as you power on,if it does then power is getting to the cd module.
The laser might be burnt out, you can try tweeking the laser potentiometer (yellow pot under the lens)slightly mark its position first with a black marker,then turn it (2 minute intervals ) anitclockwise to see if that helps to read the cd.

No, it does not do anything when I power the unit on. No movement at all.

OK, I might do that.

Does the CD32 complain if the CD-rom is unplugged?

No mechanical movement in my CD32. No light emitting form the Lens either.


@codehunter,

If you look closely at your cd32 you will see that when you lift the cd lid, there is a safety switch, that shuts it down. The only way you can get it to work with the lid opened is to over ride the safety switch.

I have no idea what your talking about, so here is a doggy with a small pancake on his head.

No, it sure doesn't, I have 5 CD 32 motherboards that I power up with the SX-1 and they function normally, they use a hard drive and I use them as a mini A1200 or A4000 when I get the time I am going to try to hook up a regular CD drive to them. Just to see if I can do it.

Hi,

That little projectile sticking out of the lid in the first picture is a safety switch actuator, when that goes into the slot it hits a safety switch and disengages it allowing power to the cd module.

Try pressing down on the with a cd inserted and see if it will work that away.
