iMac Intel Optical Drive not functioning...logic board?

Well last night I decided to  replace the optical drive (superdrive) in my intel iMac Aluminum.
Bought a compatible replacement online which was verified to work with this iMac. After removing the glass screen, the aluminum shell and finally the monitor, I took out the old CD/DVD Superdrive and repalced it with the new compatible drive. put it all back together and this optical drive isnt working either. The only difference is this optical drive did eject the cd i pushed into the slot loading drive, when i rebooted the iMac. I decided since this new drive wasnt working either, I put the original superdrive from apple, back in the imac.
Question is..Is there something on the logic board that is keeping the cd/dvd drive from working?
Please help. this drive was $90. dont want to spend more money withouth knowing the cause. any help would be greatly appreciated. thanks.

Try resetting the PRAM by cold booting while holding down the command-option-p-r key combination until you hear the boot chime a third time. This has been known to fix flaky optical drive connections.

Yes tried that. also tried pressing and holding mouse during boot, tried hitting Apple key and E, nothing. Does anyone know if the CD/DVD Optical Superdrive is attached to the logic board. Thats what I need to know. Thanks, Mark

The fact that the new drive ejected the disk on restart suggests to me the problem is not the logic board. Did you try a different CD in the new drive? Try a different type of CD, say a commercial audio CD, in the new CD drive.

Thanks for replying Strung. The Disc I forced into the replacement slot loading drive, was the MAC OS X install disc. The drive didnt pull the disc into the slot. I had to push the disc into the slot. But when I rebooted the mac, the drive did eject the disc. The original Superdrive wouldnt eject the disc. its still stuck in the drive. PROBLEM: I cannot determine where the problem is since it doesnt seem to be the drive I installed. Thanks

DId you try resetting the PRAM AFTER installing the new optical drive?

I think it is normal for the OS X install disk to be ejected on startup if you don't boot from it.

Try resetting the PRAM and insert the OS X install disk again, or try an audio CD>

What brand and model is your new drive?

The new drive was from OWC on the internet. They advised this CD/DVD drive does work with this model of iMAC. I did not zap PRAM after installing the new drive however I did reinstall MAC OS prior to replacing the optical drive with the new one, in case it was a drive issue.
The original optical drive would not eject OS disc #1. (still stuck)
The replacement optical drive did eject OS disc #2.

1. What is the make and model of the drive?
2. If the new drive is still installed, please try zapping the PRAM.

as of yesterday, i called Apple support. although my warranty is over, I told them a 1 year computer shouldnt be having these kinds of issues. if the cdrom died after a month then yes, faulty device, no big deal, they replace. but everything was fine until just a few weeks ago. they agreed to service the imac for FREE, given I did not make any errors trying to install the second optical drive. Good Customer Service, I think. I would like to keep this event open, in order to explain the end results from Apple. I will close this event out once they come back to me with the end result.

Anything can go bad. If replacing the cable fixed it, though, it sounds like the problem was the cable, not the drive.
