Why does my cd player sends back a "no disc" message?

I have a Bose Wave radio and single CD player. This is an AM/FM radio with a single cd player on top, the kind with a remote. I have tried cleaning both the cd and the cd lens. I swabbed the lens with rubbing alcohol and blew the dust out with cold air from my blow dryer. (I'm out of canned air.) The player turns on and the radio works fine, but every cd spins for a moment and then gets the "no disc" rejection. I can't find out much information anywhere else. I have tried multiple discs and different outlets, as per suggestions on other sites.

What model is your Bose?

Bose Model AWRC1G

Take it apart and find the laser assembly. You will see 2 thin metal rods in parallel which the laser assembly moves back and forth along gently push the laser to one end and use a cotton bud to clean the tracks of dust, fluff, etc., move the laser to the other end and repeat so you clean the entire 2 tracks.Then get a clean bud and can some silicone furniture polish onto the tracked, not much just a smear. Then push the laser back and forth to spread the silicone. Keep the polish well away from the laser. Do not spray the polish or it will get everywhere. Reassemble and try it. This assumes you have already tried cleaning the lens v gently with a bud dipped in alcohol or nail varnish remover. This will fix many non reading cd and dvd players. Not tried blu ray but it is the same type of mechanism. Mike

Crys, if you cleansed the lens properly with isopropyl alcohol and a lint free cloth and it still gives you the same error, it is most likely that the laser that needs to be replaced. Most likely your laser will be a Sanyo 13 pin connector type SFP100S. If you wonder how to get your Bose disassembled, here are some instructions ;-)

Note: The numbers in parentheses refer to the callouts in Figure 2.

1. Top Cover Removal

1.1 Remove the three screws (21) that secure the top cover (6) to the base (9).

1.2 Insert a flat blade screwdriver into the two locations shown in Figure 2. Apply force on the flat blade screwdriver so that the grille is moved outward and clears the two tabs located on the base.

1.3 Lift up on the top cover to remove it.

2. Top Cover Replacement

2.1 Lower the top cover (6) onto the base (9). Make sure that the ribbon cable that connects to the CD door (7) lays in the track to the left of the CD mechanism (2).

Note: The light shield (4) can get caught on the top cover. Make sure the light shield is secured in place when replacing the top cover.

2.2 With the palms of your hands located on the front corners of the top cover, press down on the top cover until it snaps into place.

2.3 Replace the three screws (21) that secure the top cover to the base.

3. Display PCB Removal

3.1 Perform procedure 1.

3.2 Lift up the display PCB (1).

3.3 Remove the ribbon cable that connects the CD door (7) to the display PCB. Remove the two ribbon cables that connect to the main PCB. Lift out the display PCB.

Caution: If you remove the ribbon cable from the CD door, you might have difficulties reconnecting the cable.

4. Display PCB Replacement

4.1 Replace the three ribbon cables that attach to the display PCB (1).

4.2 Lower the display PCB into the slots located on the matrix assembly (8).

5. CD Mechanism Removal

5.1 Perform procedure 1.

5.2 Lift up the CD mechanism (2) and solder the two points located on the CD mechanism’s APC PCB. See Figure 1. This will prevent static electricity damage to the CD mechanism.

5.3 Remove the cables from the CD mechanism’s and lift out the CD mechanism.

6. CD Mechanism Replacement

6.1 Attach the cables to the CD mechanism (2) and remove the solder from the two points indicated in Figure 1.

6.2 Lower the CD mechanism into the matrix assembly (8) so that the cables are toward the right speaker.

7. TwiddlerTM and Full-Range Driver Removal

7.1 Perform procedure 1.

7.2 Remove the four screws (18) that secure the Twiddler/full-range driver (3, 4) to the matrix assembly (8). Pull out the driver from the matrix assembly and remove the soldered wires from the driver.

8. TwiddlerTM and Full-Range Driver Replacement

8.1 Solder the red wire to the positive (+) driver terminal and the black wire to the negative (-) driver terminal.

8.2 Align the driver (3, 4) into the matrix assembly (8) so that the wires feed through

the channel on the top of the matrix assembly.

8.3 Replace the four screws (18) that secure the driver to the matrix assembly.

9. Transformer Removal

9.1 Perform procedure 1 first.

9.2 Remove the three screws (17) that secure the transformer (5) to the matrix assembly (8) and lift up the transformer.

9.3 Remove the two wire connectors that connect to the main PCB (1).

10. Transformer Replacement

10.1 Connect the two wire connectors to the main PCB (1).

10.2 Lower the transformer (5) into the matrix assembly and replace the three screws (17) that secure the transformer to the matrix assembly.

11. Main PCB removal

11.1 Perform procedure 1 first.

11.2 Remove the two lower screws (17) that secure the transformer (5) to the matrix assembly (8). Remove the two screws (17) on the left side that secure the matrix assembly to the base (9).

11.3 Lift up the CD mechanism (2) and place it off to the side.

11.4 Lift up the display PCB (1) and lay it down in front of the unit.

11.5 Lift up the matrix assembly (8), disconnect the wire connectors from the main PCB (1) and lift off the matrix assembly. Make a note of the way the wires are dressed.

11.6 Disconnect the two ribbon cables that connect the main PCB to the display PCB. Lift up the main PCB.

12. Main PCB Replacement

12.1 Lower the main PCB (1) into the base. Make sure that the nine-volt battery connector is positioned properly in the battery compartment. Connect the ribbon cables from the display PCB (1) to the main PCB.

12.2 Partly lower the matrix assembly (8) onto the base and connect all the wire connectors to the main PCB and then completely lower the matrix assembly onto the base (9). Make sure the AC line cord is inserted into the notch on the base.

12.3 Replace the two screws on the left (17) that secure the matrix assembly to the base and the two screws (17) that secure the transformer (5) to the matrix.

12.4 Lower the CD mechanism into the matrix assembly (8) so that the cables are toward the right speaker.

12.5 Lower the display PCB into the slots located on the matrix assembly.
