TOC ERROR ON DENON DN-C615

Take this info with a grain of salt. I recently received one of these units with a TOC error, and after removing the drive assembly and reinstalling it, the problem went away. Before removal, I observed the motor spinning poorly and even backwards. Rather than pull the whole drive assembly, I would first eject the drive and remove the face from the tray. This is done by putting your thumbs on the tray and pulling up with your pointer fingers underneath the face. It should just snap off and snap back on the same way. Try playing a disc now, if it works try loosening the screws on the drive assembly and shifting the assembly towards the front of the unit, tighten the screws and put the face back on. You should be good to go. There are four screws holding the assembly down, the two in the back can only be accessed when the tray is in the open position. The front two are accessible through holes in the tray, and I don't recall if the tray has to be open or not, but that's easily observable. If it's still not working, there is a flat-flex cable running to the laser assembly. Pull and reseat this gently. Try to only manipulate the cable by the blue reinforcement tab. I hope this helps!
