Sir you are a absolute genius, my player was not working for over 2 years, cds dusted and put away, after taking it for repair today, the distributor wanted an arm and leg, i returned home with it and wished i could fix it somehow since i do basic repair, amongst others i came accross your video, although very long i kept watching after seeing the comments , unbelievably it started working magically after i turned the potentiator bit by bit, just like you said, this is a very happy day for me. God bless you.
HEY, I DID IT!!!! I feel so empowered. Your video was easy to follow and I really appreciated your step by step approach. It gave me time to digest what you were meaning. Now, I'm back to listening to Mama Mia and my other ABBA favs. Thanks so much.
I'm so glad I was able to reply to your SOS! :)

Yes it works!! My Bose CD hadn't worked for about 10 years. The sound is still great. Thanks for this video.
OK pulled it apart and fiddled with the adjustment (after finding a micro screwdriver) clock wise and it did nothing , I gave up on it then said what do I have to lose and went counter clockwise and tada it is healed. I regret that I doubted you. Many thanks for the time you took to post this video and you have saved a Bose from the trash pile. Thanks again. You be bad!
Thank you for your kind words! Glad you was able to get it working! :)
Most others also said counter clockwise. But i still can't even find it
It worked for me, and my CD player works again! Thanks so much!
I should mention that the proper adjustment seems to be a matter of finding the right value through 360 degrees, like on a clock face, going back and forth and dialing it in to the point (or time) that works best. Voltage did not seem to increase for me by simply turning the adjuster farther in one direction.
Thank you!! My CD player is working again after sitting for 4 years. Easy fix, I wish I did this sooner.
Glad it worked for you Cherie!
I was able to get my CD player working again after watching your video. Thank you very much!
Thank you, works perfectly. If you plan your videos, this 25 minute could be about five minutes. Nonetheless, seriously appreciate your assistance. Also, I would have liked to see a couple of test points and know the actual voltage measurements rather than trial and error. It took me about six or seven tries, because I know with trim pots it can be a very sensitive adjustment. Each time I turned the pot barely more than a hair.
Thanks again!
This worked beautifully for my similar model. The slight increase with the potentiometer took 3 tries but with approx. 1/4 turn total in a clockwise direction did the trick. I can’t thank you enough!
Going to give this a try tomorrow. I’m optimistic I can make it work. Stay tuned!!!
Appreciate the video. This fixed the problem for me mostly. It now spins but doesn't always play the first time. But stopping and playing again seems to fix it. Much better than before! Don't think I'll touch it anymore like you said.
Thank you for sharing this information. I went out on a limb on an eBay purchase. It paid off with your guidance.
Thank you for your video God bless you I added a Bluetooth receiver on mine from amazon now mine has Bluetooth literally the best thing ever but I have one without the cd changer 👍
I have this exact Bose with this exact problem. I'm sending my husband this video, and hopefully, he can fix it!
i am looking into a 60-year-old little-known yet highly recommended product called DeTox It for audio, video, and just about any electrical component. won't harm plastic! Amazon.
Thanks for uploading this fix, exactly what was wrong with my unit. now working perfectly.
Dude !! This actually worked ! Thank you very much. I've had this thing since around 1997. Love it.
Glad you found it helpful Stephen. Thanks for the comment.
Que tal se escucha?
Another fixed cd player in tbe uk. Thanks for posting this!
Hi. Many thanks for the this video. I gave this a try. Before problem the CD would keep spinning and spinning and then 'disc' logo. Tried adjusted the resistor like you sho LLwed, but CD would spin twice, stop, spin twice and then 'disc'. Kept trying to adjust and put back but no luck. Any ideas please? Best
Sorry, I no longer work on these devices because they are now past their lifespan. You can try making small incremental changes from one extrema to the other. However it is most likely out of tolerance capacitors at this point in time.
You are a genius man, thumbs up...💯
Thank you so much cant wait to fix my Bose I have experience in PCBs and setting pots so should be an easy fix. Will add my comments after giving this a try.
It worked and found cleaning the front plastic I could see the clock better. Was very dirty. Thank you for this video saved my radio.
Thank you so much for the tip. CD player working fine
So glad it was helpful to you! Thanks for sharing! :)
What a timely video. I salvaged a not-working wave radio like in this video from a garage and have got it working now. I turned the potentiometer approximately 1/4 turn and it now works. Thank you so much for sharing your work. I hope it's reasonably safe electronically to have adjusted the potentiometer like this?
Paul Paradise hi, no problem! Yes, I turned it a tiny bit twice and it didn’t go, the third increment got it going. I could get the player working if I manually spun the CD with my hand, quickly closed the lid and pressed play so I think it was “only just not working” as it were. Listened to a number of CDs now, makes a good kitchen CD player in my house! Best regards
This worked perfectly. Thank you!
Hey, it worked also for my unit! Thanks for advice!
And I guess the CD gets spinning lower at higher tracks because the player is afraid of the end and wants to prevent the CD beeing finished earlier. ;-)
Thank you. Excellent.
Your instructions made the CD of my wave radio play again.
The essential advice is within 11min and 13 min. You really need a small screw driver to make this resistor turn. But it worked - whao I was already about to throw it away.
Thank you Tom! So glad this worked for you. Good advice about the small screwdriver. That is a must for accuracy too.
I have a model AWRC-1G that I need to try and fix the CD player that you show in your video. Problem is, I can't get the top off of it. I removed 2 screws in the back and 1 screw by the CD. It will not come off in the front. I do not see any other screws. Can you help, what am I doing wrong?
There are two black plastic tabs on the bottom in the front that you need to pry the white cover over. A plastic pry tool will be the best way to do this without damaging anything. A screwdriver will also help but you risk damaging the plastic.
Hope this helps. I just did this Today, but turning the screw CW and CCW didn’t fix mine.
This video is A great help though!
Brilliant video. Just helped me fix my CD player. Thank you!
My Bose Wave has been radio only for years but thanks to you it’s now back in action on CDs. Quite nerve-wracking turning the potentiometer screw by stages to a total of a half turn. It started to start/stop at a quarter turn. Took it slow as you said. Thank you so much. Question -why would Bose build in a fix for a problem or did they hand adjust this in manufacture? Stay safe. Regards from Scotland.
You are correct in assuming they adjusted them by hand in the factory. The issue is not so much the potentiometer, but the fact that other components (such as capacitors) change values with age. This leads to varying voltages throughout the circuit. That is why a variable resistor was used instead of a fixed value.
Wish you had included getting the case apart! Regardless, great video, thanks.
Actually, I didn't include it because TH-cam would not like all the cussing it takes to get it apart! 🤣
THANKS MAN! Much appreciated! Tom, UK
Very helpful `~ thank you
I have a similar unit. The CD player only reads a disc if I manually push the laser assembly a bit closer to the spindle. I hear a plastic click as I do that, but then it will play the disc properly. The time to read the disc's table of contents takes up to 30 seconds afterwards, but it then plays all tracks OK. It will NOT read CD-R discs, but this is older technology (c.2000) and I know some older units do not recognize CD-Rs. What could be making the laser assembly seem to not return fully to the innermost position ? A damaged set of cogs in the tracking assembly ? Not sure how that could happen ? Any ideas. You do not show if it is difficult to remove the casing as the video jumps over that part of the disassembly.
Very helpful video. Thanks!
Got mine CD player finally spinning after this turning the potentiometer however no sound. Turned it some more, and now it doesn't spin.. tried for 2 hrs to make it spin, still no good. diode still lights up tho so maybe the laser isn't burnt out? Please advise!
@@ElectroRestore but would that be possible even if radio works? Im def get sound through radio as well as the aux port
I think I turned it to much the first time and tried to turn it back, now I’m not sure where I started from. Any way to get it back to factory settings to start over? Thank you
Unknown. At this point start all the way counter-clockwise and go from there.
Great informative video! Thanks for posting.
Thank You TheButtonBoxMan!
Glad you enjoyed it! :)
I have the same model Bose, with the same CD read problem. I'm going to try your fix. Thank you. By the way, my LCD dimming feature stopped working recently. It seems to work in reverse now... Dimming under lit conditions, and brightening at night. Annoying when trying to sleep. Any ideas?
Sorry I miss this MrTuralon, I am not sure about the LCD dimmer components. I would need to have it on the bench to troubleshoot it. It's about 75% trial and era on my part.
Gonna try this!
This is a brilliant video and a prefect fix, can you help me with this problem, when I was putting the case back on I dislodged the ribbon that is connected to the case, how can I connect this back up?
I've tried the potentiometer adjustment without success. I get the platen to rock back and forth 3 times without going into a complete spinning mode. Is this indicative of bad laser system?
My CD is NOT spinning> I replaced the 9 Volt battery, I removed case, I see LASER, hit play, disc rotates slightly, then adjusted potentiometer 1/4 turn clockwise multiple times, then reversed multiple times. I was reluctant to turn the potentiometer more than 1 complete turn in both directions. Still not spinning any suggestions. Also the volume buttons on the unit not functioning, but does work w remote.
This is wonderful information.... i have bose wave 2 with 3cd changer...
1. WMS doesnt spins CD...hives error NOT PLAYABLE. I checked after opening 2 top panels of CD mechanism..trying giving it push start as well didn't worked ..any idea what cud be done to get it to work ...
2. I have CD changer it doesnt gets detected by WMS...I think the boselink cable might be faulty is it there anyway it can be repaired ...I dont have any spares available...
Some expert tips wud really help here
I got a used Wave Acoustic CD-3000. The radio works great. The CD player spins the CD and the display shows it started but does not begin to play. There is a soft clicking sound and will not play. I have tried different discs. What is the likely cause? If it is not an easy fix, I wiill be selling it on eBay for parts within the next week but I would rather fix it!
Where do you get one of those screwdrivers?
So I have the screw driver. I managed to get it spinning better but never sound. Now I when I turn on CD, it just says disc and nothing working. Oh well! Wasn’t working before amd still not working.
@@Monique-tz8wv Sorry it did not work for you. It is most likely a circuit issue and not the potentiometer. Unfortunately there is no technical docs released for this Bose. They refuse to make things available to repair folks. It is better to them for you to throw it away and buy another one. The world we live in today is really terrible compared to the good old days! :(
Ive just bought a AWRC36 With a non working cd player , it seems the optical eye is missing are these available to buy? I am in the uk .
Hi Bimsb6!
I am not sure if they are still available in new condition. Your options are to either purchase a used "parts" unit and switch the optical diode. Or you can possibly try and switch one from a used CD player.
I bough a few of these for $10 each from a Las Vegas casino liquidation sale.
Thanks lot :-) very helpful :- :-)
I am experiencing the same problem on 2 of my bose awrc-1g. I do not see any laser lights on either on of them. so I purchased two new laser heads and still no laser shows on the new heads. You mentioned that you need the laser lights showing before adjusting the potentiometer. Any suggestions?
You will need to check the voltages and ensure that the power is being applied to the circuit. If so, the optical boards may be bad.
My problem is fixed.I removed the solder from the new sanyo laser heads (SF-P100 for Bose AWRC-1G or AWRC-1P) as directed per video on Removing solder from SF-P100 laser head on TH-cam. Both units are working great now.
Never located the adjustment screw. Cd played about a week then stopped again.
I am sorry to hear that you was not able to get it going. To be honest, It has been a while since I did one of these. I am not exactly sure, off the top of my head, where it is located. The video should show it though.
@@ElectroRestore
During that section the video is out of focus. If i clean the lense with a alcohol it will work fine for a few weeks then needs cleaning again. That doesn't sound electrical to me.
@@rlowle1228 the potentiometer can be clearly seen at 11:22 - 11:30. I point right at it with a screwdriver. ;)
Great video! In the process of removing cover, my ribbon cable to cd lid became disconnected. Now I cannot seem to reconnect it. Is there a secret to this?
Ribbon cables can be difficult. Just don't force it. Some have a locking mechanism you must adjust to insert it. If your does, be sure to lock it after it is inserted.
@@ElectroRestore Thank you so much for the reply! I can't tell if there is a locking mechanism. It's inside the lid with very little room to work. It seems to me it would be much easier if I could disassemble the lid. Can't find out how to get it apart. Do you know the lid assembly can be disassembled?
Thanks,
James
@@jamesbrinkley2306 I'm afraid I can't help you with that because I honestly don't remember. I am visually driven and can do a lot with a unit in front of me. But I work by logic, not memory. Sorry.
I just went though this with my lovely old Bose AWRC3P that I have had since new, and now I am listening to a CD of Anna Lapwood playing the organ. I saw her not that long ago at the Proms. The only gripe I have with your brilliant video is that it took me ages to get the top case away from the bottom, but I found that on another site: th-cam.com/video/oxervf409Ig/w-d-xo.html so I am a happy bunny. Thank you very much. I found altering the potentiometer screw was a bit random but it was no more difficult than doing sudoku and more rewarding.
I know this is a year old video but want to put it out there that I have a cd player and probably other parts if anyone is interested.
