The CD drawer may be stuck because the motor has become weak or the mechanism is binding. You will have to do some disassembly to troubleshoot. Any good quality wire will do for the speakers; you don't need super premium stuff for your application.

1. Most of the player drawer fixed over the chasis for a rigid support
2. try to remove the drawer safely without damagind the chasis and drive mechanism
3. there might be some shaft jam.
4. Look for the thread. how does the player drawer moves in and out
5. there may be some sensors to sense the door close/open. if it is jammed then open/close function cannot be done. why because this problem occurs
6. unwear the mechanism read the mechanism moving technique. see which has got jammed.
7. if you feel too risky then

Does it show the disc length or any other details? Have you carefully cleaned the lense with a q-tip and some alcohol? Can you hear the laser moving in and out of focus? If you push the laser sled out away from the centre does it move back to the middle when youi put a disc in?

The tray belt raises the laser to proper focal length at the end of closing the drawer. This demands more grip from the belt. If the belt is sloppy, it will slip at this point, even though the drawer is shut. Took two years of repeatedly cleaning lasers to notice this.

this player uses a philips mechanism, spindle motor failure is very common on these mechanisms, yours may be on its way out. take the lid off and insert a cd and if you can hear the laser trying to read the cd without it spinning, it's definately the spindle motor.

The display flashes "closed" and I can't open the cd drawer when pressing the open/close button. Is there a reset please ?


Try removing power from the unit, let it set two minutes without power and power it up again. See if the problem continues.
Make sure the cd drawer is complete closed and flush with the front panel. If not, something could be stuck inside.
Turn off power and remove cord from wall for next step:
There is a small hole generally on the flat face of the cd drawer through which a bent straight paper clip can be pushed gently until you hit a mechanical stop. Pushing slightly harder at this point should cause the cd drawer to move open mechanically. Gently pull the cd drawer open until you can remove any CD still inside.
Gently push the drawer closed again and restore power to the unit and see if the problem returns.
Would be nice to have manufacturer and model number of the CD player.

The Optical Pickup(laser) has worn out. When you place a disc in the drawer, it has to load and read the TOC(table of contacts) if if can't read that, it assumes there is no CD in the drawer and stops or ejects.

Pressing the 'open' button on my NAD C542 CD Player no longer opens the disk drawer. Any suggestions to fix this would be appreciated. Regards Michael


G'Day Michael,

Having fixed thousands of CD players in my career, and also being a NAD Authorised service guy from 1989 till recent times, I can comment with some authority to your situation, and correct some of the ill found assumptions given to you already.

This unit uses a KSS213c transport. Very common and used in many machines, also relatively reliable.

2a8af3a.jpg
The drawer load motor is not shown above. Is will be mounted on the black plastic load assembly. The drive belt/motor for it will be under the tray runners.
If you do not hear the motor run, then it WILL NOT be a broken or failing belt. However, this is the most common problem with this style of transport. I would be checking anyway to see, the load motors do free run fairly quiet with no drive belt connected. Wind the tray assembly out by hand by kicking the gears over to open the draw to see the belt/motor

Because you cannot get it to work from the remote, AND you have "open" indicator on the front panel, it WILL NOT be a faulty front panel button(never seen one fail ever!)

I have never replaced a load motor to a Sony transport. Spindle motors can be a problem, but they never stop working altogether.

I would be checking the tray mechanics, a jam caused by something fouling the gears may cause a fail. Tap the front of the draw as you press eject to see if you can encourage it to work.
Sometimes, small nylon drive pinions can split, the excessive gap in the gears caused by the split causing a bind. Check also for blown pico fuses in the servo drive stage. This will cause no drive to the load motor.
If you cannot pin down the source of the problem, the player IS welll worth repair. These machines sound great and would have cost you a few bucks to begin with. If you need help locating an expert NAD authorised repair guy I can help.

Happy to discuss any of this further with you. As previously direct your comment to me by name. Cheers

regards
robotek

WIthout knowing the specific model, I can't be 100% sure, but a number of models in that vintage had a problem with cracked ribbin cables that go to the drawer unit. Replacing the cable usually fixed the problem. What is the specific model number?
