Denon DN-S3500 After using the scratch wheel just to cue the disc, the disc runs on fast when started. help please what can i do?

Hi, firstly check that the discs are not too scratched and be aware that CD's read and play from the inner diameter to the outer diameter. CD players are really finicky devices that can be affected by the slightest bump and also temperature and humidity changes. Sometimes decks have a humidity sensor embedded in the circuitry. So, all that being said, firstly just turn the set on and let it sit for a while to heat up and dry out especially if it hasn't been used for a while. Then, take the lid off and check for broken drive belts that actually spin the disc. (You may be able to hear the disc spin without the top off). After that the laser itself will have to be cleaned, adjusted and the current checked. Lasers do wear out and sometimes increasing the current to the laser will make it read for a little while longer. You will need the schematic diagram and some decent equipment and knowledge to achieve this though. Since they both don't work, and you got them for free, they might be good experimental pieces but, in my experience they are never 'time' worthwhile repairs. Good luck. Cheers

Will it play the disc,s?

The encoder probably has dirt or dust in the pickup. Remove the wheel and clean the sensor area.

If you would like to change the fuse yourself here is how:- Use a flat screwdriver or a knife and insert it where i have marked in yellow. Then push the plastic lid out with the picture of a fuse.Replace fuse and press the lid back.

clean the lens...if it does not work replace the lens.

Try changing the platter speed from 33rpm to 45 rpm The menu for this should be in the preset section on the player.... Good Luck

I'm having a similar problem. Basically I put it a disc, and the song titles show up, but it takes over a minute for an actual song to load. I don't have a solution, but I am in contact with Denon, and they're, so far, pretty cooperative.

HI,

Please reset the unit for 4 hours by unplugging all the cords,even the power cord from the unit and then plug them back again after 4 hours.Now try ejecting the disc.Let me know the result.

Sounds like it may need a motor calibration. You would have to seek out an authorized service center to this adjustment done. It's a quick and easy fix though.
