I had a CD that would not play in my 5910ci. I knew the CD was fine because it played fine in my Shanling SCD-T200C, Pioneer 47Ai, Pioneer 578A, Pioneer 58Av, my clock radio/cd and in my car. I took the covers off to determine why this was the case. Well, was I in for a shock!
No wonder there are so many complaints of discs not being able to play. The drive clamping device system is simply awful. The top is a plastic spindle snapped into a thin stamped sheet metal housing cover that is screwed to a plastic housing with self-tapping screws. Real precision pieces. NOT. Cost about $1.50 to build. Utter crap. I thought this was Denon’s ‘State of the Art’ player. The bottom is a tapered brass spindle with a piece of rubber stuck to it. The laser travels along steel rails that are secured into a PLASTIC housing. Again, real precision pieces. LOL.
So when the disc drawer closes, the bottom tapered spindle moves up into the center hole of the disc and continues to move up and make contact with the top plastic spindle in the cover. Problem is, the plastic spindle is not stationary so the bottom spindle may not come into proper contact, hence the infamous ‘Denon Shake Rattle & 00.00.00’.
Secondly, the force that the bottom spindle presses up against the top spindle is not sufficient. If the center hole in the disc is tight, the spindle does not have enough force driving it to press into the disc hole, hence ‘00.00.00’. IMO, this is a Denon DEFECT! All of my other players, all at a fraction of the cost of the 5910, can at least clamp the disc properly. This was the case with my disk. I took a sharp knife and scraped the inside edge of the CD centre hole and reinserted it into the player. Viola, no ’00.00.00’, just music.
As you may well know, the 5910 is a VERY warm (temperature) player. With all the plastic and thin sheet metal on the drive, no wonder all the problems. Plastic and thin metal may change slightly because of the heat inside the player. This may change the alignment of the laser which may then not be able to read the inserted disc, hence the ’00.00.00’. The laser is mounted on the two steel rails. At the back of the rails, where they fit into the PLASTIC housing, there are adjusting allen keys to align the laser. If you want to DIY (very easy), may I suggest that you FIRST turn in (clockwise) the allen key all the way and COUNT the number of turns, in case you want to set them back to factory settings. I will post this in a few forums for those of you that want to address their 5910’s read problems.
