Blimey, it's like hearing my own voice and thought patterns! Excellent.

This is awesome! It fixed my bose solo tv system! I had a unit that did not power on or show any other signs of life. At first, I thought it had to do with the power side of the board. It didn't. Eventually, I traced the fault back to the Texas instrument Ic with the help of another video on youtube. I'm not experienced in working on electronics whatsoever and I thought that the chip was dead. I had a few 100uf 16v capacitors laying around, so after watching this video I gave it a go. It worked like a charm. The unit powered on and for the last couple of hours, it has been working like new. I did not change the crystals. Thanks a lot for making this video! We saved another one from the landfill. All the best from the Netherlands.

Thanks for this movie! My device was saved :) My case is: the device played for 2 hours and went into buzzing state. Turning off the power, turning on and playing another 2h and buzzing again. Another shutdown and the device no longer turned on. The power section was ok. The exchange of crystals didn't help. The use of two pieces of 100uF / 25v capacitors did the trick. The device turns on every time, it played for 5.5 hours and there was no buzzing effect. Cheers.

I do all sorts of electrical repairs but have never messed with Bose much since they are so tight lipped with their information. One thing I have noticed is that some are saying the pads pulled off from the board when trying to replace thses caps. I have learned that if you heat them properly and twist them slowly they will come off without taking the pad with it. In other words, don't pull stright up on the cap (crystal), twisting slowly instead.

Very informative video! Also servicing one right now. Startup beep but no LED. Goes into standby after some minutes (all switching supplies enter their standby mode with audible whine). Already swapped the 24.5MHz crystal and experimented with extra decap, but no fix. Bit clock to the DAC looks a bit weak and L/R clock looks slow, but since the startup sound gets through, should be OK. Question: The regulators in the bottom right produce 3.2V IO voltage and 1.26V core voltage for me, is that correct? Could be OK if the proprietary DSP is similar to a TMS320VC5502. But could also be low if the DSP has a 1.8V core. I guess I will try to swap the other crystal next.

Without getting my hands on it, my guess is that you have a problem with one of the power amplifiers. Check the large Capacitor at the front-centre of the board is OK. After trying to start for while you could unplug and see if one of the amplifiers is warm. If it is then the chip has blown. It isn't a foolproof test (if it is total short it wont get warm) but might point you in the right direction. To check If I suspect there is a short on the DC side - (voltage should be around 24 volts), I disconnect the mains supply, and connect a 24 volt DC feed direct from a bench power supply. If you get high current and the power supply voltage is pulled down then drive the power in for a while at a couple of amps and see what gets warm. If the voltage rail stays high I would suspect the power supply side under the can. Note you need a bench top DC supply capable of delivering a few amps current at 24 volts DC. Good luck. Stay safe.

Rare to see someone this knowledgeable! Very interesting. I have a question. My SOLO only switches on if I I warm it up in the area were the IC is located. It is a strange phenomenon. I had it open to check why it would not switch on. Power Supply, infrared system, supply of IC, all OK. So I concluded it was the IC which I cannot repair. The SOLO was standing on a home heating unit, not too hot, I think about 60C. And once warmed up it started again to switched on/off normally! I had it running non-stop on medium volume for 48h. No problems. Once I switched it off and it cooled down, it stopped reacting to the remote. Same procedure again: I positioned the SOLO on the room heating and after warming it to about 40C it started working again without any problem. My question: which element is heat sensitive? If I could identify it, I could repair it! thanks

@razenby

2 жыл бұрын

It could be a DSP start up problem or the flash memory or instability of the crystal clock. The DSP is very sensitive to the relative timing of the rise of the 1.7 and 3.3V rails - even if reset is held low until they stabilise and the release. i.e. It has experienced some form of lock-up even before it has been reset, I don't know of any other processors that do that. Any HF noise on the 1.7V line will crash it before it boots. I have fiddled and fixed a lot of Bose kit with Texas DSPs fitted. The problem is that Bose have a custom part number for the DSP so I cant be sure which device it is. I doubt it is a custom DSP but Bose has the custom part number so you cant get any support from Texas. The Texas dev system wont recognise the DSP's ident via the JTAG interface. I manage to fix about 70% of the Solos with DSP issues. . Probably about 15% of those start playing up after a few months. On some I have adjusted the 1.7V rail voltage by a smidge (core supply) and it solves the issue. there is no doubt in my mind that this kit has marginal digital design issues. It is running ion a knife edge. I have reversed engineer other Bose kit so I can flash with the JTAG instead of using the Boot loader. Anything you can do to reduce the HF impedance of the 1.7V rail will improve it. Most Bose kit that use a DSP will sometimes start up and run if you warm the DSP but this is a temporary solution as time goes on they get more reluctant to start and eventually wont start at all until you intervene. I have five units here that I keep meaning to get around to but paid work is getting in the way. ... Good luck...

The video shows two 100uF 25v capacitors, not 46 6.3, am I missing something? Also you say 3 caps at the end of the video

I have the same question as Silviu. Additionally, do you think this will fix a unit that does not power on at all? I know you can't guarantee anything, but an educated guess?

I have one of these

Good luck with it

hi, sorry but i don't understand your video well because i don't speak english well. I have the same device, which the first time did the buzzing and I solved it with a firmware update. It worked 3 months and is now completely shut down. I checked on D1301 there are 24V. Could you tell me the components to replace to make a repair attempt? Thank you

On pin 9 of the integrated circuit Fan7384 there are connected a 0603 resistor with an sot323... Can you tell me the value of this resistor please?

The guy that sold it to me said he had it in storage it was working perfectly fine but he did issue me my money back it’s still in its original box it’s something to do with not being used I think

@@brittbear4577 He could be correct. Good on him. Memory chip data, capacitors, cheap crystals don't age well. Ageing is expected but if the design is marginal, function is marginal to start with. When components age as expected then it leads to problems. So many Bose products fail to these Schoolboy hardware design issues.

Call of the dogs.. I was able to reweld it better.. Green light is back on.
