20 Most Recent Yamaha CDC-585 5-Disc CD Changer Questions & Answers

Honestly, when the mechanical parts wear to this extent, you're better off to buy a new CD/DVD player, since they are so much cheaper than repairing older units.

See if the tray motor drives a belt to move the tray, if so, check if the belt is loose or broken and replace if necessary.

You can find replacement belts in electronic part stores and on internet, you need to measure the diameter of the circle that the belt forms so you'll know what to purchase, but keep in mind that the new belt will be of a slightly smaller diameter than the used one).

Also check the tray homing switches for dirty contacts or physical damage and clean/replace if necessary.

These switches are usually of a touch contact type (something alike relay contacts that are being pressed to make a contact when the tray is in either of the extreme positions - open or closed).

It may as well be something else like tray motor control section, loose wires or connectors, physical damage to any of the tray drive gears or other tray parts, a stuck/obstructed gear... i only described two of the fairly common problems that often cause the tray mechanism to fail or malfunction.

Hope you can fix it...

Hi. there is a tiny limit switch that regulates the actual CD platform drawer(The part where you lay down the CD). this switch if faulty. it is designed to shut of the load motor when the CD tray is fully inside the unit.

this limit switch must be replaced. this is a job for a qualified Yamaha service tech. contact Yamaha for this repair.

The drawer belt may also lift the laser up to meet the CD . If the belt is bad , the CD player will kick out the CD.
Change the belt.

Hi..
It will have to have the coverr taken off and the drawer belt replaced.
Find a stereo repair place.

I have a very similar type unit, a Nakamichi CDC-3 that had the same problem. I found this link....

I spent about two hours fixing mine. The sled mechanism was binding somehow, causing random skipping. The first 10 minutes was getting it apart and figuring what was wrong, the remainder was spent getting all those tiny parts back in the proper place.

Look up the exact symptom before going at it (probably long skips). Set aside a long slow lazy day with nothing to do. DO NOT drink too much coffee, you will be handling tiny parts that go in tedious locations, so you don't need caffeine jitters adding to your misery. Take your time and be careful. It's well worth it. Mine plays like a new one.

I expect there is either a power supply issue or one of the amplifiers has failed causing over current to turn it off as a protection to the power supply.

"Opening" ... Please explain what you mean.

Yes if it has a suitable speaker connection available and is nominally 8 ohms impedance Speaker and AV.

Being from 1985 or there abouts, it probably needs some TLC at a Yamaha service centre. May need new capacitors and resolder dry joints for age related issues.

WD-40 ... Very dangerous as it not only flammable when wet but is bad for electrical contacts as it leaves a residue behind that does not conduct electricity very well. Check speaker connections first.

(francais) hello in my issue the probleme was a little resistor r027 it's in this red zone and very ugly. easy to find. a friend was unsolded the resistor and weld a little wire after wash with isopropanole alcool. the resistor test the tension when we plug usb thing. less the resistor the usb ports don't work. you can buy r027 for 2 euros for 100 pieces.... or 2 euros for 5 10 pieces (funny).

Follow the procedure as given in following link. RX-V6A ' ENJOYING IN MULTIPLE ROOMS (ZONES) (yamaha.com)

Question edited for clarity, full make model (what it is)'. Question moved to Yamaha Audio. It may be sympathetic vibration and is coming from something nearby. Put it on a folded towel or sit in the floor to test it. https://www.google.com/search?q=YST-FSW050+bad+vibration ..

You must repair the amplifier first. Take it to an authorised Yamaha service centre.
