When removing the side vented panel, remember to pull the treble and bass knobs off before hitting the grill. They just pull straight out.

Also the panel below the vented side is not glued on to the cabinet but uses a rubber gasget and therefore the electronics and speakers can be accessed without damaging anything simply by removing the screws .

There is a latch on toward the rear in the seam between the plastic and the larger wooden box. Turn the latch until it sticks out. Make sure the side nobs are pulled off first then....

pull very hard on the black pastic away from the plugs and it will come off.

    I quote: "On the end opposite of the jacks (top of the sub opposite connectors)
    in the exact middle, there is a ratchet looking device (flashlight and
    magnifying glass reveal the little culprit) with a very small flat
    screw driver rotate the piece CCW until a small tab is protruding from
    the middle. Pu the palm of your hand on the plastic case and give it a
    small whack (in the direction of the jacks) it will move about a 1.2
    inch. Lift straight up and the case will come off and reveal the
    connectors. Trust me, get a flashlight and magnifying glass and peer
    through the small crack between the cover and the box, you will see the
    little notch (encoder looking) rotating wheel
    "

    The instructions are not provided because they do not want users to open the device and do service on their electronics, and this is also against the low in many countries.

    The guy that published the manual is not really an expert.

    I will give you broad instructions on how to remove the cover, if the unit is under warranty (less than one year ld) do not open it, but call the service number on the user manual.

    I report the whole procedure, case is the same as Acoustimass 15: "Even if you are an accomplished EE Bose will not provide the required schematics to troubleshoot and repair this unit.



    Still undaunted then IIRC this is the same case as the original LS-25
    series and there is a catch at the end of the cover furthest from the
    input connectors that needs to be rotated, which you can do with a flat
    bladed screw driver, and you also need to remove a few screws from the
    bay where all of the connectors reside. Then tap the case with your
    fist at the far end and it should then slide off.



    Note there is not going to be much you can do to fix this beyond
    replacing the fuse. (Note that the fuse is soldered in.) The bass
    amplifier is op-amp based with discrete class G output stage and the
    twiddler amps are monolithics with discrete class G circuitry shared
    between several channels.



    The power transformer has a thermal fuse in it as well which is not
    replaceable. If you play the unit loudly for long periods of time and
    it is not adequately ventilated it is possible for the thermal fuse to
    open - if this is the case you will definitely need to send it in for
    service.



    When plugged in there are hazardous voltages present on the top PC
    board where the power connector is located, whether or not the unit is
    turned on.



    Power switching is via a triac controlled by whichever front end you
    have CD-5? 12V should be present on the mini plug (tip I think, but
    might be ring) when the music center is on..



    There is also offset detection circuitry that will latch the unit off should any output have more than a volt or so of offset.



    IMO This really is a job for Bose customer service. Sorry I can't be of
    more assistance, it has been a really long time since I left the
    company."

Multi cd bose player will not eject 4th cd.


OK, this problem is everywhere with the bose cd changer addon. Many people can still play a cd with the top one fine, but cannot get cds to eject and/or read in 3 disc changer. My friends mom had one and after finally hearing back from bose, they said send it in with $100 to get fixed. If you have to send in and you value your cds, you may want to open it up and get them out. Use this at your own risk, there are no warranty stickers I saw and there will be exposed voltage, shock hazards, etc.; so if any of this worries you, stop here. By proceeding, you are admitting that you are capable of minor repairs and therefore I'm not responsible for any damage or harm caused. OK, here it is:
Unplug everything. On the bottom of the cd changer unit are 4 screws (silver ones recessed about 3/4" or so, use phillips screwdriver) to remove. Turn unit upright again and lift cover slowly straight up. In the front of the unit is a ribbon cable you will want to disconnect that goes to the cd 2-4 lights. Take note which side the dark blue tab is on and gently pull out by dark blue tab, rocking side to side if needed) You can then pull cover all the way off and set aside. Plug power into back of cd changer (careful not to touch anything inside) and see if the cds want to eject now. If not let the initializing process finish and repeat. This time see if you can gently help the cd out. The problem may also be the spindle not lowering, you can look for this movement during the last step of init. process. Work your way fom the top tray down removing the cds gently, remember we open it up because they were valuable to us, don't destroy them now, and don't ever use anything that could possibly scratch either top or bottom of the cd, use edges instead. Start to replace cover making sure to reattach ribbon cable back into socket the same way it came out. do not force too hard or you may crease and break ribbon. Gently replace cover and grab both top and bottom to turn over. Replace 4 phillips screws making sure not to overtighten or cross-thread. Now you may return to bose or just find an independent repair shop in your area, they are usually quicker, more polite, usually cheaper, and best of all, local!

Bose wave radio/cd often cd spins but does not play, sometines will correct if I turn unit off and on. HELP tHANKS


I've repaired about 10 type Bose AWRC3x (the radio/cd model with lift up lid and top controls). If the cd won't play or skips, try cleaning the lens VERY carefully with a cotton bud with some isopropyl alcohol. Let it dry then try again. This will help in about 1/3 of cases.

After that, a new laser unit is needed. They cost around 15 pounds,30 dollars, (Type SFP100s with 13 pin connector made by Sanyo). You need to have some electronics experience to take the case to bits to get the laser deck out, change the cd laser and reassemble. Basically, DISCONNECT THE POWER! Remove the 3 screws on top, turn over and carefully prise the front of the base away from the top cover with a table knife or similar. Lift off the top cover - be careful with the lid ribbon! The deck can be disconnected from its ribbon cable and wired connector very carefully. Take the deck to bits and fit the new laser head (take photos if you think it will help). Remember to unsolder the shorting 'blob' of solder which protects the new laser from static till its fitted.

On the bright side, there is no tracking etc to set up, that's all automatic so usually they work like new with a new laser fitted. I have to say this is the weakest feature on the Bose CD radio, the actual electronics rarely gives trouble.

Hope this helps Steve O'Donnell
