I have a Denon 2900 CD/DVD player and it players CDs just fine but struggles with DVDs. It usually wont even begin to play the DVDs, and when it actually does it will freeze up and not respond. Also the door will not open at times. I can hear the motor trying to push the tray out but it just seems to stick on something.

Thats how some manufacturers sell there replacement parts as they come into the country assembled. it cost let to import but more for us. i once needed a spindle motor for a unit, no replacement except the manufacturer part. Had to buy entire laser assy and thats what they bare selling you too. If you already tryed to manualy clean the lens, look on the side of the laser pick-up. it might be made by sony or a popular manufacturer go by the number printed on the label on the side or bottom of the laser assy unit itself. Good Luck

Hi,

There has been a number of reports of similar issues with Denon models that utilizes the 'PureProgressive technology'. Some of the issues and tried corrective measures are -
1. It would appear that in certain occasion, performing a "region free hack" disables the 'PureProgressive technology' and one solution tried is to set the unit to NTSC and not multi or PAL;
2. disable/turn-off digital output;
3. some has reported significant improvement when a firmware upgrade was performed;
4. use DVI instead of of other outputs.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

SOURCE: DVD tray makes noise when it rotates

This noise can be casued by two things:

1) The tray is not completely in the loaded position and the "clamper" is rubbing. Replace the loading belt and the loading sequence will complete and the noise should stop.

2) The "CD table" that is part of the spindle motor assembly has slipped a bit. This will make the CD/DVD ride too low and strike the lower tray support. This will require that the table be "re-aligned" to the proper height which may not be possible on your model without special measurement equipment. The height is critical to proper operation of the unit.


Try replacing the load belt first and report your results.

Thanks,
Dan
