NAD 523 CD Player Tray Door Won't Open

[@bananaking2828]

Thanks for the video, i went straight to the tray drive belt on mine, but still the tray was jamming. There is a gear train driven by this belt, after patiently removing the tray, i was able to free them up. all good now.

What is the repair for a try that won’t stay open, it closes as soon as it reaches the end of open

[@emersonferreira7851]

hello friend, I'm about to buy exactly this cd player, what is the number / model of this optical player? Do you usually have reading problems? could you give me your opinion on this device?

[@VintageAudioFan]

The optical pic-up assembly is KSS210B (from MFR's part list). I looked up my unit which is labeled as KSM2101BDM ( the laser pick-up with motor chassis assembly). My 523 doesn't have any reading problem when playing the pre-recorded CD or home-recorded CD. So far, I owned few multi disc CD players including Yamaha (2) and Sony (3). I still play my NAD 523 a lots. It is very quite when it is playing. Although it make some noise when changing discs, but I don't think it is worse than my other CD players. Smooth high, tight bass, good sound stage and image. My impression of NAD 523 is very positive.

@@VintageAudioFan thanks brother.

@@emersonferreira7851 You're welcome. I just uploaded a complementary video explaining how to remove the door tray for the belt replacement. Also I included an operational and listening test (jazz/vocal and classical music) at the end of the video if you are interested. Thanks.

[@evan8tor21]

which website did you use to order the replacement part?

[@VintageAudioFan]

Because I got this CD player free, so I don't want to pay a lot for the belt. In fact, I bought the replacement from eBay. The item title call "2020 repair 60pcs 40-130mm mix cassette tape machine square belt assorted". I just selected one (the closest size) from whole package to replace it and it works.

Enjoyed the video, but having trouble understanding you.

I am adding text on my video so it should help.

How do you hook it up

[@VintageAudioFan]

The belt can be replaced without removing the drawer tray out as I showed in the video. It may take a little time but you don't have to remove the face panel and unplug wiring cables. I also can send you a video which explain how to remove the front face panel and expose the drawer open/close motor drive assembly which includes the belt.

@@VintageAudioFan I don't get the new belt hooked up. Can you please send me the video which you have mentioned? :-)

@@timosteuerwald6789 Sorry, I forgot to make a supplementary video (more detailed one) due to my other repair projects. I will post it as soon as I have it. Thanks.

It’s a nice little bonus piece of gear but very noisy eh ?! Darn Chinese stuff Not built to last

[@VintageAudioFan]

In fact, it is pretty quite during playing CD. But it makes noise when changing the discs. Overall, the sound quality is not bad. These multi CD players always have problems mechanically.

[@williamchow1624]

Since your belt is still in one piece, try boiling it in water for 15-30 min in a microwave.

[@VintageAudioFan]

I did try it with your suggestion. It works but still a little bit sluggish. With the restoring belt, it opens tray without problems, but it needs push when closing the tray sometime. I only boiled it for 15 minutes just for experiment.

[@williamchow1624]

@@VintageAudioFan Try boiling a little longer, up to the 30 minutes. I was told to do this by a former technician that repaired video equipment at a television station. This method usually restored the belts.
