Johnny thank you so much for this fix, I had exact same issue, replacing the diode brought my unit back to life. Quite bad design for something like this to take out a quite expensive unit after such little use. Thanks again, I wouldn't have been able to diagnose and fix this, would have been in the bin.
Thank you jonny for uploading the repair of this I was able to repair one of these greetings from Colombia infinitely grateful
Thanks for the video Jonny. Same fault on my Bassmodule 500. Now operational. You saved me $150.00.
Thanks to you I fixed mine in 30 minutes. My testing was identical to yours. I replaced the diode with a 3amp through hole diode. You saved me a ton. Thank you.
Awesome!
Where did you buy the diode
You can get them from many places like element14, rs components, mouser, digikey etc, whichever is more convenient for you@@franciscotorres5113
You just saved mine! Thank you! Saved me soo much time! Awsome!
Can i buy this diode on amazon?
Johnny thanks for your video I enjoyed it. I was able to fix my Bose Subwoofer with a 1$ part. Appreciate it so much!
Impressive! Well done !
Thanks for sharing!
The same problem, the diode shorted, thanks for the content 👍🏼
Nice fix Jonny 👍
Great video usually that's the culprit. Last time i turned on the module burnt that very same ic and welded it to the board
Many thanks for this video, I fixed mine too, so happy !! 👍👍
Tris video saves my like 500 usd, thanks a lot 🙏
Great video and I had the same problem. Thank you!!
Hi Jonny, you made my day!!
Thank you. My issue was the exact same diode. I just save myself 150 buckssss!!
Awesome ! thanks from Italy!
Thanks! Saved me a lot of money !!!! My unit works now 🎉
Awesome, thanks for the support!
Got mine fixed! Same problem. Thanks a ton.
Well done!
Great video and very informative 😊 are you able to show us how to repair a Wii console - making rough noises when loading a cd
Very interesting job ! thank you my friend
Cheers mate!
Is that status amber or white?im having problem connecting to the soundbar,and mines amber status supposed to be blinking white to connect?and i think i put the thing backwards because the light supposed to turn off right?
Nice fix!!!
Well done jonny :-D
I'ts a shame that they didn't put a bigger mass diode on that pcb.
Penny pinching buggers :-(.
Will a third one appear on your door step lol.
Where do you buy the diode from
Thanks man you saved me
Hey Jonny fix. Thanks for great guide. My bass module turns on but gives no sound and led blinks red. Any idea what that could be?
I've not seen this fault sorry. The user manual may give some idea as to what LED state means.
Hi, I have one of theses bad boys, I checked the pacifier I have 0 not 27.79 like yours. I’m in the us, where can I get components? And thanks for the video, so much info.
You can get parts from mouser, digikey, element14
can you please help me to fix mine, where are you based
Hi Jonny my bassmodule 500 started to pop every once and a while. I followed Bose instructions by moving it to different locations, plugging in different outlets, etc. None of that helped. I returned it to Bose who sent it back after four weeks claiming to have repaired it. It’s now worse than before. Would you have any idea what can be causing the popping sounds?
Could be interference from wireless router or something else in your area. If you have one, turn it off and see if it stops. Try another location, at a friends house etc see if it happens there.
@@JonnyFix I decided to try using a shielded audio cable instead of wireless. That looks to have fixed the issue so far. Disappointed with this product though. Thanks.
Would be interesting, if Bose uses a better Diode, if you use their repair Service? Do you have any Information?
Unsure what they use. I imagine they would only upgrade it if they agree there is a pattern failure here while under warranty otherwise it's probably original spec. Given the years they last I don't think they see a need for it but anything's possible.
Please could you tell me if you used the same diode you used for the bose 700?
Yes I did
I tested across the diode and get 1.0 ohm. Bad, right?
Sounds like it
Hi! I have the same problem with my Bose bass 500 module. Total newb here. I noticed you replaced the diode from B340A to B2100. Would you recommend me doing the same? Or sticking with a new B340A diode?
Either will work just fine
@@JonnyFixif I’m getting a reading of .3 ohms, does that tell me the diode is not the problem?
@@ianpascua8690 0.3 is too low if you are measuring each end of the diode then it's bad.
I did exactly in the video and it worked for a good 5min but now it won’t turn on again, I checked the diode and it does not beep on either side
Do you know if I need to replace the same diode again?
Hard to know. A should only go in one direction. Did you put it in the correct way? When testing use diode mode on multimeter and put red lead on the end without the stripe and black lead on other end, you should read about 0.3 to 0.5 volts, with the unit unplugged of course. If not, try a new diode. Otherwise you have some other fault. Check soldering and make sure it is connected well.
Those things seem jinxed.
He I have Bose subwoofer 500 not working can you help me fix it ?I can shipping for you.
Sorry mate, I don't accept mail-in jobs. Find a local repair tech and show them this video it might help them.
Thanks for the video, i have the same problem, but i can’t fix it, so i hope somebody can help me.
Hi Jonny, first, thanks for the video. I m sorry because my english sucks but i have the same trouble than you, no power.
I m not good at electronics but i tried to check the same diode than you and i don t understand how do you know he is fucked ?
When i test it on OHM mode, it sounds like you with a beep and show 0.5 OHM.
Thanks for helping and sorry once again for my english
Loïc
Your english is pretty good. 0.5ohm is bad, replacing it will be a good start.
Thanks!
Much appreciated! Glad you found it useful.
Hi Jonny,
Thank you for your video and time !
I have this module and it suddenly stoped emitting sound.
I followed every instruction about reseting the device without success. The bass Module cannot be detected wirelessly, it appears to be somehow detected by the soundbar when plugged with a 3.5mm jack, but even then, no sound at all. Even the powering on sound doesn't exist anymore. Any idea how to start my investigaiton ?
Not sure how you mean detected by sound bar. Does it have a light on? If no light maybe it's not even turning on so could be the problem in video. If there is a light I don't know sorry, I haven't seen this before.
Wow sorry to hear about that. These speakers are expensive, I would have thought that if you pay premium, then that's what you get.
I was thinking of buying one, but your post made me get cold feet.
Did you end up resolving the issue? Was Bose taking responsibility for this?
