CD player does not spin up - No Disc msg

Tray closes, and the spindle closes on the CD, but does not spin.

I have been trying to find the function sequence (algorithm?) of a cd player. The drive should spin next, then the laser trys to track?? Is this usually done within the drive unit? The drive motors seem to be mounted on their own boards. I can manually turn the tracking gear to move the laser to the the outer edge and it will move back to the center when the CD is loaded. Does the laser function effect this. How can I tell if it is active?

It is a JVC component unit (MXS2) CD-Receiver-Dual Tape. With the cover off, two connectors and a couple screws and its out of there. I was hoping to replace the drive unit with some hope of success, as opposed to paying mega shop rates. What are the chances that parts (the whole player unit..) are available for a 1993 model anyway?

Thanks
Randy Robbins

gently push the cd door back in while pushing the door closed button , untill it closes if it still comes out then the cd laser mechanism is not lifting or something else has happened , then it will need to be tested to determine the exact cause

The most common mechanical problems that can prevent a dvd player from playing...


The most common mechanical problems that can prevent a dvd player from playing or reading the discs are the following:

1. The spindle motor not functioning properly (this is by far the most common, if the spindle motor is not spinning the discs then the optical lens can not read them). For the most part it is an cheap part to replace averaging around 25-35 dollars if you can replace it yourself. If you do not know how and have to take it to a repair shop expect to pay 50-75 dollars in labor. The key is to listen closely when you insert the disk into the player, you should be able to hear it spin up. If you hear nothing then that is most likely the problem.

2. The cd tray could be out of alignment. This is another easy and cheap fix if you have the proper tools. This could happen if you drop or pull and push on the cd tray.

3. The small gears are plastic and often break, this will cause the players other parts not to move and function properly also. They are hard to get to, but inexpensive to replace from the manufacturer. A visual inspection is usually required to determine if the small teeth have been broken, which requires for the most part taking out the carriage assembly.

4. The small belt drives either break or come off. Again, this will cause the other mechanical parts not to function. They are a pain to put back on also. There are usually 2-3 of them inside your player. These are located in the drive assembly and will usually require removal of the optical reader assembly to be able to get to them.

5. The Optical reader has malfunctioned. This is the most expensive thing to replace, so you might as well buy another player unless you can find a great deal on one someplace. You can check to see if the laser is firing with a visual inspection (DO NOT LOOK DIRECTLY INTO THE LASER) put in a disc with the case off and you should see the glow of the laser hitting the disc.

6. The tray also has a drive motor which can fail and cause the cd tray not to open and it also has a track that it rides on. Check these two components if you are having problems with your cd tray. The picture below shows the drive assembly with the tray open.

My rca rs 1289 5- cd changer mini system will not play, open, close, or change cds. how can i fix this problem at home?


Remove the case screws on the left and right side panels. Pay attention to the long screws that come out of the middle of the panels to make sure they get back in the right spot. Remove one screw from the top rear back panel. Lift side panels of in a hinged motion from the bottom. Remove the top panel in a hinged motion from the rear. In the center of the disc tray remove 1 screw from center. Note the orientation of the tray for re-insertion. Lift the tray up and out. look for small dc motor and spindle. this motor is used to spin the tray. You should find a black belt2_bing.gif between motor and spindle. Make sure it is in good condition. Look to the right rear of the unit. there is a second motor and belt which drives the tray. This belt may be broken or off its spindle. repair or replace the belt as necessary. Plug the unit in and test the open/close function and ensure the gear train, belts2_bing.gif and carriage move smoothly. reassemble.

I have nad c541i,for last few days,it not reading the cd,as the disc goes in,there's a bit sound from the spindle which goes off after 5 secs,but doesn't read the disc,the screen keeps flashing like --...


this has the sony mechanism so if you take the lid off and unscrew the 2 screws, 1 at either end of the cd clamp and remove it, you should see part of a large cog just under the front of the cd tray, try turn this clockwise and the tray should open.
once open, you should be able to see a small plastic cover, loosen this slightly and replace the belt as this is prone to slipping on this mechanism stopping it clamping the disc properly when closed.
the sound you say is the spindle motor, is actually the loading motor trying to lift the whole laser mechanism up towards the puck to clamp the disc as there is not enough tension left in the belt.
help it along by hand and you'll see what i mean.

hope this helps?

My NAD C251i CD player isn't reading disks - platform stops short


To fix it, you need to replace the spindle motor top bearing. The bearing is worn and the player mistracks as the armature moves about under the changing drive conditions. Makes the player mistrack and skip. Because the disc is spinning fast.

Replacing the bearing should resolves the problem.

Hope this helps and have a great day!

Error code HO2 appears after inserting dvd panosonic NV-VP30EB


Hi,

To my knowledge, most H02 errors on a Panasonic DVD player would indicate a spindle error, that is the central motor that spins the disc. Normally, this would require an in-shop repair as electronics is involved, however, you could still try:
  • close the tray with no disc inside;
  • press on the back skip, pause, and play buttons simultaneously and hold for about 4 seconds;
  • when the screen blanks and then "initializing" appears, release the buttons.
Alternately, you can try:
  • remove the top cover;
  • clean the spindle motor with compressed air;
  • manually turn the spindle counter clockwise and then clockwise numerous times to exercise the motor;
  • power on the player, insert a disc and manually assist the disc to start turning.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Permenant "Unknown Disk"


Try cleaning the player with a DVD lens cleaner.

If you're adventurous enough, and the player is out of warranty, you might want to open up the player exposing the lens part. Then, try to eject and close the disk tray and see if the laser diode lits up (avoid staring at the laser light, it will ruin your eyesight! View it from the side not directly into your eye.)

Also check if the spindle spins a little. Or, with the top cover open (this magnetized cover serves to hold the disc firmly as it spins), insert a disc into the tray and close it. See if the spindle spins with the disc.

This problem points most of the time with either a bad laser or misalignment. If misalignment is the case, this could be fixed by carefully turning (very slowly...) a tiny potentiometer located near the laser diode (experiment with the best setting, mark each turn and try any disc with each turn. Be patient)

This fix is not for the faint of heart, and at your own risk. If you're not sure of what you will be doing, leave the servicing to a qualified technician.

Marantz CD48 - CD spins backwards


Check the small signal transistors BC338 and BC328, they're under the transport mech and will be near where the spindle motor plugs in to the PCB.
One of the transistors acts as a brake which momentarily puts the motor in reverse polarity to stop the CD rotating during 'stop' or 'open tray' modes. The reason the CD is spinning backwards is that the transistor which drives the spindle motor forwards during playback is faulty and is triggering the braking transistor hence spinning backwards.
The transistors should be 'BC328-25' / 'BC338-25' (25v)
Replace these and all should be well.

Hope this helps
