Question about Numark MP-102 CD Player

Tray won't open, no buttons work

Brand new out of the box MP-102.  When I turned it on, a red light was flashing on the pitch control 16% button.  The tray would not open.  I turned it off and back on, and now nothing works except that the display is on and everything it can display is displayed.  I have turned it on and off several times.

    hey just bought a new CD Mix 2 and CD A or tray 1 sticks and often won't open.



    i wonder just how reliable Numark CD mixers are? i'm in two minds now as of course i will return but fear this will happen at any time which could be compromising!

Return it. do not open it up or you will void any warranty. There is either a disconnected cable or a logic/power problem. In any case, a new piece should work out of the box.

CD tray won't open or close on onkyo dx-c606 cd changer.


Yes! it sounds very likely that a small loading belt has stretched, or the loading motor is not working, this is not an easy repair because the gears are timed and synced to work together, if the unit has a loading belt pull tray all the way out and look in the empty tray, may be visable! if you can remove it without taking it apart all the better, have a Tv repair shop size up the belt for replacement.

Cd tray won't stay open--when you press the "open" button, it opens but then closes again immediately.


It has a misaligned loading mechanism. I have dealt with this kind of problem before. What is happening is that before the tray have a chance to open all the way it gets stuck and gets pulled back in.

Powers on fine, but won't eject tray.


There's a small rubber belt driven by a motor that turns the gear which moves the tray. It's probably stretched and is slipping. You can usually get at the belt by manually opening the tray and removing the cover from the player. There's usually a small hole on the under the tray where you can insert a straightened-out paper clip to open the tray. A TV or stereo shop can probably help you find a replacement belt, or you can order from online suppliers. Measure the belt circumference, and get one about 10% smaller since the old one is stretched.

You can find the remote control codes for different brands of devices from
http://www.hifi-remote.com/ofa/codes-tv.shtml#tv

If none of the codes work then we have two other solutions:

1. Searching For Your Code

If you have tried all of the set-up codes for your brand of equipment ,or your brand is not listed, and you are still not able to get the unit to respond, try the following procedure to search for your code.
If you don't find a code that works, the remote will flash four times when you reach the end of all the codes for this device type.
  1. PRESS the button for the device you want to program, (TV, VCR, CABLE, etc.), then RELEASE.
  2. PRESS and HOLD the SETUP button until the red LED flashes twice, then RELEASE.
  3. ENTER 9-9-1 (two blinks on the remote)
  4. ALTERNATE slowly between the POWER key and the DEVICE (TV, VCR, CABLE, etc.) button until your device turns off. (On VCR, LD, and CD players use PLAY instead of POWER)
    Make sure that the remote is pointed at your device during the search, You may have to press this sequences of buttons up to 100 times to search the entire library of codes.
  5. When your device turns OFF, PRESS the SETUP button and RELEASE it to lock in the code for your device.

2. Learn the buttons from the original

Line up your original remote and the head-to-head before completing the following steps.
  1. PRESS and HOLD the SETUP button until the red LED flashes twice.
  2. PRESS 9 - 7 - 5, the red LED will flash twice.
  3. PRESS the DEVICE key where you wish to learn the function. The next 3 steps must be completed within 10 seconds.
  4. PRESS the button that will receive the learned function, the LED will flash rapidly.
  5. PRESS the button on the original remote to be learned.

Now you can repeat steps 3 through 5 to learn other functions onto other keys or press and hold SETUP until the Cinema's red light flashes twice to lock in your new feature. (If the red light does not blink twice, stop and repeat steps through 6).
To test the new feature, press and release the device key in which the new feature was learned followed by the key on which the feature was learned

HHB-830 CD TRAY does NOT open.


It's made for HHB by Pioneer, you could try one of their agents?. Opening up is fairly straightforward if you are methodical and take your time if you need to. There is a test mode sequence you can try - hold down the 'menu/delete' and 'auto/manual' keys together for 5 seconds until the display blinks all the lights then press the stop button. Now ONLY press the open / close button - pressing any other keys will change settings and without the service manual you won't know what you're changing. Press stop then power it off to exit.

I can email you the service manual if you need it. It sounds like a gear has come loose inside to me. I strip these machines for parts quite regularly so may be able to help you out if you're able to work out what if anything is broken but I'm in the UK. It may be as simple as a belt has come loose :-)
