sonos gen 2 sub repair

I'm glad to hear you are back up and running. I will know br Tuesday if I was successful. My only concern is D15 is not a schotkey diode.

We are a select few who have repaired these devices. So the question is what  is the root cause that makes this part of the circuit fail ?  I guess we can only speculate !!

Just tested the Sonos Sub2 and it is fixed.  Components changed were C85, R37, R77, Q16, Q10, D15 and the TL5001. Thanks to all of you who helped me with this. I sourced my parts from Alibaba, the shipping was more than the parts.  Yippee !!

Really appreciate everyone's effort in extending the lives of the sub for as long as possible, the information gathered here is really helpful! 

I don't have any technical ability so I've just been relaying information from this thread to my local repair guy and he mentioned to ask the forum for "U7 8Pin definitions and input/output voltage". I'm hoping someone knows what this means and what the values are. 

Thanks everyone! 

Your repair guy  can Google 5001c for the data sheet. It's  a PWM. It was easier to just replace the chip than to pull out the oscilloscope and try to determine if the chip was bad. All the parts I changed including the chip iare available from China. Delivery will take a few weeks.

I hope your repair guy has experience with SMT.

Good luck.

Hello, I just repaired my sub with the above components suggested and now my sub is back to work again. Thank you so much guys. I have paused the repair over the last one year as I was living abroad and did not have the opportunity to fix the unit. R73, R77, Q10 had burnt marks at closer look under a scope. For Q10, while less obvious, its drain and source were shorted even though it is not biased.

R37 - 1kohm 0603

R77 - 1ohm 1206

Q10 - 7P1 sot-23 P-Channel mosfet

Q16 - 2F sot-23 PNP

D15 - B280 Schottky Diode

Glad to hear you got it fixed. It's great that there are forums where  we can get together and pool our knowledge to keep our stuff running.

Absolutely! Hope that more owners of this sub will benefit from the fix. 

Don’t know if someone can help me out in where I could buy all these parts. I have a sub Gen 1. I will be doing it myself hopefully everything goes smoothly. 

condensator smd 1210 1uF 100v (C85)

resistance smd 0603 1K ohm 01B (R37)

resistance smd 1206 1 ohm 1R00 (R77)

Transistor 2F SOT-23 0,8A 60V (Q16)

Transistor ZXMP10A13FQ 7P1 (Q10)

Diode zener B280 13-F (D15)

Hi Aghitman77, you may find these components in sites like Digikey, Mouser or Aliexpress from China. Perhaps Aliexpress is a good place to start for cost effectiveness. https://www.aliexpress.com/

Hi,

I bought all my parts from Aliexpress. Q10,  Q16, the caps, resistors,  I also replaced R37,R77. Ic  TL5001.

Q16 is a 2N2907   I used a 2N2222

.D15 is a 2A  100V Shottkey, I used a 2A100V. Not a Zener

Check R37 and R77. Both were shorted or open

The parts are super cheap at Aliexpress. L paid more for the shipping than I did for the parts. The  delivery date is 3 to 4 weeks.

Good luck
