Hi MS, A great video thoroughly enjoyed it. I have the same Bose product which is faulty. The symptom of the faulty is high pitch squealing noise then no output. I am a retired electronics tech that can swing a soldering iron, and an AVO but, would appreciate a hand. I plugged the unit in and all worked fine. I believe something to be overheating? Nothing obvious. I intend to reflow the joints around the mainboard and then soaking to see if that helps. I am electrically safe (most of the time).

Hello Magic Smoke. I am currently working on the exact board. Did this indeed fix the unit? I am about to replace the smaller semi conductors on the bottom like you did, just wanna see if this is a viable first step to diagnosis it. (Also what is the name of the smaller chip your working at 20:17?) Do you think, that diode missing was the issue or the two small chips underneath? (Obvs it wouldnt work without the diode) but was it the diode missing or those chips failing + the transistor (Maybe the person who worked on it thought it was that, but it ended up being what you replaced?) Will post a video of my findings soon.

The smaller chip looks like a SOP8 memory chip. If this is the case, you would need to transfer the information stored in that chip to the new chip before it would work. Great video for someone looking to diagnose their Solo. In my experience with the Bose Solo soundbars, the failure always seems to be within the Bose firmware. Either a bad solder at the chip or the chip has taken a turn for the worse. Also, wasn't the last part you soldered onto the board a MOSFET? There is a great way to check these types of gates without having to remove them.

Firmware fails and no way to force into a loader without a serial JTAG programming interface. There is no startup checksum warning event though they could flash a LED warning sequence. re the DSP the start up sequence and timing of the power lines is crucial else teh logic can hang up and a hard resent wont make it start once the change has happened.

Hello MS! I watched with great interest all the videos on the Bose Solo, hoping to get some ideas on fixing mine, but no luck. My problem is the same as several others who commented here, namely, no beeps, no LED coming on, nothing. Power supply is definitely putting out 24VDC and linear regulators in DSP section are putting out 3 and 1.7VDC. There is no 5V on the USB port. I’ve also checked the remote and know it’s working and signal is getting to the processor. Clearly, without the start-up beeps unit is not ready to receive any input from the remote. Without a schematic, even though I’m an electrical engineer, I have no idea what to do. If you get one of these Solos, as there seem to be a lot of them failing the same way, I’d love to see a video on how you go about troubleshooting and repairing it. Thanks in advance.

Hello Magic Smoke, I watched your videos as a friend of mine asked me if I could try to repair his Bose Solo TV device... I was wondering if maybe you could help ! The device behaves like if it was totally dead (no light, no initial sound, nothing). The remote is working fine (sending infrared frames at least !). Inside the device, I performed a visual inspection and it looks fine as far as I can see, no leakage, nothing burnt or exploded. I checked the power supply part of the main board and the mains (230v AC) is entering it ok, reaching the bridge rectifier, then I get around 330v DC at the bridge output. However, I have absolutely nothing (O v) at the output of this power supply section (I understand from your videos that I should measure around 24v DC at any of the 6 capacitors filtering the ouput signal). I removed the STX616 NPN transistor and tested it with a little multi-function tester and it looks ok. Do you think it is still worth replacing it by a new one or shall I look elsewhere ? I even tried to inject 24v DC to bypass the power supply but, no better (though I see there is 1,8v and 3,3v available around the Texas chip). This Bose device is evil :-) It is driving me crazy as many other people as I can see in the video comments ! Thank you for your help and congratulations for your videos which are great 🙂 Rgds,

When I power the soundbar without the acoustimass the white led is there but the green led blinks. I checked the PSU and I get a stable 24V. So I then checked the DSP board but I can't find any faulty component. I don't have an oscilloscope on hand right now sadly.

@@razenby Well, I did investigate and I think Mikhail had the same issue. The problem seems to be the Spansion FL128PIF (located at the back of the DSP board, it has a sticker on it). Either bad connection or the chip is dying. I resoldered it and my soundbar is back to life now but the chip may eventually need to be replaced. If so, I guess it would need to be reflashed? Do you know? Thank you

Great Video but way to advanced for me to start messing around with - I have the same system no power whatsoever. do you know of any repair centres in the UK please - will be a shame to throw this one in the bin!

Have you checked that you have DC across the reservoir capacitors? I dont have time to fix anything at the moment as I am working on a new design.

Unlikely that only the comparator is faulty. You need to change all the parts stated to make it work else it will go bang when switched on.

Hello Magic Smoke! It was nice to see your video, thank you! I have also a problem with a Bose Solo 15, but I think that it could be a little bit different. It is also not powering up by the remote controller but I have 24V on the last capacitor which you were checking, I have 5,9V on the capacitor in the middle section, I also checked a IR received diode and there also is a voltage. How can I contact you?

Hi Daniel, If you have the DC as you say then the DSP system section may be playing up. I assume that it is totally dead when powered up (no power on beep-beep)? If you get the beep beep then have a look at the remote control LED with you cellphone camera. Believe it or not the remotes often lock up too. Hold on for a few I want to try a recovery procedure on the bricked unit I have here. I'll make a video about it, If that doesn't work then Ill take a look. Ed.

@@razenby Thank you so much for your answer! I can not hear any beep, a diode on the front of the soundbar is not turning on. Ichecked also remote controller with a camera, I can see the light with a mobile phone camera. I checked a voltage on the IR receiver and it is also coming there, voltage is also changing when I am using a remote controller, so it looks like it is receiving a commands, but it is not doing anything, not turning on. It is still in the standby mode.

Sorry, I have my hand full with a development contract at the moment,

Hey Magic Smoke my dad donated his Bose Solo to me a few weeks back . He had been having problems with it not turning on and replaced the battery in the remote which didn't fix it. When he left it unplugged for a day then plugged it in it would turn on and run flawlessly for a couple of days. Would you be willing to take a look at the power supply board if I mailed it to you?
