- This is a full disassembly, repair, and reassembly of a Bose Wave Radio that is suffering from the "Please Wait" error.
I was able to get the radio fixed by replacing six capacitors on the main logic board.
Model # AWRCC1
Electrolytic Capacitors were purchased from Digikey in the US.
Here is a link to my saved cart that includes extra capacitors from the entire main board (I only ended up needing to replace the 6 capacitors as shown in the video):

!CAUTION! The quantity and values of the capacitors in your radio may be different than what is included in this list even if the model numbers are the same. Please check your unit for the exact values and quantities.
_______________________
I replaced a total of six capacitors within the metal shroud as follows:
1- 100uf @ 6v P803-ND/ECE-A0JKA101
2- 22uf @ 6v P800-ND/ECE-A0JKA220
2- 10uf @ 16v P807-ND/ECE-A1CKA100
1- 47uf @ 6v P802-ND/ECE-A0JKA470
In my parts list I ordered extra quantities of these values since they were inexpensive (in case they got damaged during the repair). I also went ahead and ordered the values for the capacitors outside of the metal shroud just in case any of them had failed since I didn't know which ones were actually bad.
A few viewers have asked how to determine the polarity of the capacitors. Here is an article that will help with that: www.digikey.com/en/blog/ident... - Věda a technologie
Thank you for this great video and especially for posting the Digikey cart. I was able to fix my 80+ year old mother-in-law ‘s Bose Wave radio that she and her late husband use to enjoy and now she can enjoy it again. She is really happy. Almost brought a tear to her eye hearing it working again.
Just one personal preference suggestion, I replaced the caps one at a time so I wouldn’t get mixed up. I also put a piece of electrical tape on the board to indicate the polarity so I wouldn’t mix it up after removing the bad cap.
Thanks again!!!
You are welcome. Glad I could be of help.
My wave radio is doing just fine, but I saved this vid and subscribed just in case! I've replaced caps on other electronics before- it's a pretty straight forward fix!
Thanks Tom! Great job and adding the capacitor shopping cart was a great resource!
Glad you liked it!
Fixed my parents Bose with your instructions and the helpful digikey cart. Thanks so much!
You're welcome!
Thank you! I was going to throw away my parents Bose radio. I used your DigiKey cart and replaced the caps under the metal shield. The darn thing is working again:) The CD player wasn't able to play discs. I happened to have an old Kensington Drive Guardian cd cleaner disc. I ran that in the CD player and now that works as well. Thanks again.
Glad I could help
I like to thank you so much for your video on how to fix my late father's bows CD radio. All the parts came in like you had ordered for yours took my time and fixed it myself with the education my late father gave me on how to solder with a pencil solder. Thank you so much for your help with this many happy years to come.
Glad to be of help.
Thank you Tom for your video and automatic link to the caps list. My wave radio is back up and running. Pete🎉
Glad to help
Thanks - this was exactly the problem with my Bose wave radio. Got the 6 capacitors from DigiKey, followed the video, now it's working great. In my case it was the 47uF cap that had gone open circuit with no capacitance. I have a meter, measured all 6 after removing them, the other 5 were fine. Maybe this saves someone else time if they want to try just changing the 47uF first ?. Appreciate the video, thanks very much.
You're welcome!
I don't understand the order of the replacements I ordered all the Digi key caps but he doesn't say this one here is this specific cap and so on. I don't have any idea which one goes where. I'll try just the one you said to try first. Once I figure out which one that is😊. Maybe I just missed the order.
Thanks! Thomas 🔌
Glad I could help
Great video, Tom. This gives me confidence that I can do the repair by myself. I have an AWRCC2 model which is a white color, so the capacitors should be the same to your AWRCC1. I have few questions though... 1) Which capacitors did you use on your list (items 1-8)? 2) Why did you not use the same style SMD aluminum electrolytic capacitors but instead you used through-hole electrolytic capacitors? 3) What size of the solder lead and what size of the solder iron tip did you use? Thank you
1) I added the list of capacitors I replaced to the description.
2) I chose to use radial lead to make it easier for my large fingers and large tip iron to work in the tight spaces. I don't have SMD tools and didn't want to mess things up. Personal choice and familiarity with the technique also played a role.
3) Solder=Plusivo 60/40 0.6mm 15% flux. Tip is a T12-BL (and with the braid I used a T12-K tip)
@@thomasfilliman5072 Thanks a lot, Tom. My AWRCC2 is having "please wait issue" and CD skipping. My priority is to fix the "please wait issue" so I am going to replace the six caps. Hopefully, it will also fix the CD skipping issue. Thanks for sharing and helping people how to fix their bose AWRCC1/2.
Good and clear info, except no mention about how to determine polarity of the capacitor on the capacitor itself and on the board which is vital.
The black stripe on the surface mount capacitors is negative. Also if you look closely at the board after the caps are removed you may see a tiny white dash near the pad that is the negative.
I'll post a link in the description to a blog article from digikey that shows how to read the polarity of capacitors.
Thanks for watching.
Thank you so much for this video. Could you explain the actual capacitors you used from your shopping cart list? I am a complete newbee, and I'm looking at the capacitors in my unit, trying to determine how to decipher the difference between the R4 10 16v and Q4 10 16v. Are they interchangeable? Thanks
I think you are referring to the markings on the original surface mount capacitors. In my Bose unit each capacitor has 3 lines of markings. Top line is a series code and can be ignored. Middle is the capacitance in microfarads and 3rd line is the max voltage rating. So R4-10-16V and Q4-10-16V are identical. However, each capacitor manufacturer codes things differently, so if the values are not rational then you might need to look the codes up on a chart.
When referring to the parts list I posted, I did add some extra quantity to a few of the values just so I would have a spare cap in case I messed up the soldering job or needed to replace more capacitors elsewhere in the unit.
Thank you so much! Based on things I was reading, it seemed they would be interchangeable, but I wanted to ask and hoped you'd reply. THANK YOU!
Hi Thomas, thanks for the video! What are the DigiKey/Panasonic part numbers of just the six capacitors you replaced on your list? I think my numbers are similar but I just can’t read a few of them. My Bose Wave II is a model AWR1B2 without CD player. Thanks for a reply. Steve
I replaced a total of six capacitors within the metal shroud as follows:
1- 100uf @ 6v P803-ND/ECE-A0JKA101
2- 22uf @ 6v P800-ND/ECE-A0JKA220
2- 10uf @ 16v P807-ND/ECE-A1CKA100
1- 47uf @ 6v P802-ND/ECE-A0JKA470
In my parts list I ordered extra quantities of these values since they were inexpensive (in case they got damaged during the repair). I also went ahead and ordered the values for the capacitors outside of the metal shroud just in case any of them had failed since I didn't know which ones were actually bad.
Regarding hard to read values: If the voltage is hard to read you can always use a 16v rated part. If the value is hard to read then you may have to guess and find a value nearby. These capacitors typically have a tolerance of 20% and the circuit design may allow for a wide range of values depending on the purpose. So you can always purchase a few possible values and just try them in the radio to see if it makes it work. Without schematics it is impossible to know for sure but many of these capacitors are used for filtering and the exact value isn't that important.
Thanks! - exactly what I needed. Just placed my order with DigiKey.
Thanks for the digikey cart. Ordered, received, and installed. It now works with fm, am, and cd, but the clock won't hold a setting and the speakers make popping sound when turned on and off. Any suggestions to complete the fix? Thanks.
Sorry, I have no idea.
Hi Tom, I also just noticed that my capacitor supplier substituted what I ordered a 47uF 16V with a 47uF 25V. Will this affect anything?
Also, when looking at the 6 capacitors that you replaced, several of my original Bose ones are listed at 6V but I ordered mainly 16V replacement versions.
Please let me know if this seems like a concern before I continue my repair. Thanks!!!
Replacing with the same mfd but higher max voltage rating is okay. The capacitor will be physically larger which may impact making the cover fit but electrically it is fine.
Perfect. Thank you!
Hello Tom: I am working on a Bose Wave II AWR1B2 that does not power up. Nothing showing in the display. No visible damage to any capacitors so far. 1) Is there a way to power up the unit without the remote? 2) should I replace the 2 larger capacitors on the main board as a first step? 3) what else do you recommend I check. Thanks in advance for your assistance. JL
Hi, as I don't have access to that model I don't know how it should operate. But as a guess I'd say that if there is no display that maybe the power supply is bad, or something on the logic board (such as a shorted capacitor) is causing the power supply to shut down. Before replacing components I would check voltages with a multimeter on each of the boards. If no voltage than you could check for shorts with the power supply disconnected. Other than these initial steps I have no other thoughts.
Thanks Tom..... I used a heat gun "wake up" the controller. I've ordered parts using your parts list. Thanks for sharing your expertise and the link to Digikey!!
@@joelinkousjr.3234you’re a genius! The thought of replacing those capacitors sent me back to 1979 micro soldering courses in the Navy. I completely forgot about the heat gun trick that we used all the time to get something working. Wife’s hair dryer for about 3 minutes and moved it off the cold back porch. Music is Bose on!!
Also a shout out to Tom for a fantastic video!!!
Hi Tom, How do I determine the polarity of the capacitors on the original Bose board? I understand that on the new ones, the longer lead is the +. However I don’t know which is + and - on the old originals. Thanks. Sorry for the simple question.
The black stripe on the surface mount capacitors is negative. Also if you look closely at the board after the caps are removed you may see a tiny white dash near the pad that is the negative.
Lead length shouldn't be relied upon exclusively. There should be a polarity marking on the side of the new capacitors that indicate which lead is negative.
See this blog post for examples: www.digikey.com/en/blog/identifying-capacitor-polarization
Wonderful! Thank you so much. I am beginning the replacement of these 6 capacitors now.
I replaced the caps per your excellent video but the CD plyers says Disc Unreadable. The cds play in my cd player just fine. Any suggestions?
That is a bit harder to diagnose. Could be anything from mechanical affecting tracking, to dirty laser pickup, to something electrical. You could try recapping the capacitors near the cd connector or purchase a cd mechanism to try. Good luck.
Could you tell me where to buy the six caps? I think I can do this with your great video! Thanks for posting it.
The link to my digikey cart is in the description. There are more than six capacitors in my cart since they are very inexpensive compared to shipping costs and your radio might need others that mine did not.
Ok. Got it! Thanks.
Great but did the cd player work correctly?
Yes, everything worked correctly after the indicated capacitors were replaced.
Yes, the CD player did work, but the extension 3 CD player did not work. Again, thank you again for the video.
Are these worth anything when they say “please wait”? I’m probably not going o fix it, but hate to trash it. If I can sell discounted that’s best.
You could try to sell it on ebay, broken units go for about $70us.
Thanks! @@thomasfilliman5072
Thank you. Could i send you my system for repair? I am in Virginia, and i do not have the tools to fix my Bose Wave system.
I don't repair units for a living so I would be reluctant to offer to do this. Since the shipping costs both ways would be significant I suggest you just sell your broken unit on ebay or similar sites listing the problem for prospective buyers. Someone then may decide to pick up your device to fix it or use for parts.
What's the part number for the 6 capacitors?
The digikey shopping cart should be linked in the description. Is that not working?
