[EafD] Sonos Playbar Repair - Part 2
Вставка
- Опубліковано 22 жов 2017
- Quick video I made on the fly whilst repairing a Sonos Playbar that wouldn't power on. Turns out after replacing some parts on the PSU it's now up and running - check the video for details on components replaced, and testing tips.
FET = Toshiba TK6A65D, RS part 8962420
FUSE = RS part 2260585
Primary Cap = RS Part 7260754
PWM Control IC = ON Semiconductor FAN6300HMY, RS Part 7396074
Glad I found this. Rather than try to repair the PSU I just cut the PCB in half just to the left of the mains inlet, sanded the traces to remove the copper mask, soldered +ve to the top and ground to the bottom. Bought a 6a adjustable PSU from Amazon, set it to 16v and hooked it up. Works perfectly. If the PSU fails no need to rip it all apart again.
My Sonos playbar was not powering up and I was fortunate enough to find this video. On mine the PET had blown as you could see a tiny burn mark on it. Anyway I changed that, capacitors/fuse and bridge rectifier.....I happy to say it's all fixed and running again. I can't thank you enough for the info you provided here as I wouldn't have been able to fix it without this. Saved me a fortune and saved the planet too. Well done.
Thank you Ohmslaw. Although my knowledge of electronics is not enough to understand everything you explain, your videos did help to test the board and find what was wrong: one of the wires of the first filter coil (capacitor choke) was broken. Easy fix. The most complicated part of the repair is putting everything back together again 🙂
Great video and explanation. Just repaired mine. Blown was the rectifier in front of the 2 caps, part KBU606. This component is easy to check with an multimeter directly on the board. If blown, it creates a short circuit. Replaced with a rectifier taken from a PC power supply with higher value.
Great tip with the power supply instead of AC input. I was afraid to play with power supplies. Used a serial bulb circuit but of course it's still dangerous. Your way is great, I love it. Thank you ♥
THANKS for the video and the rest who commented! Found one Playbar for 800 Danis krone (~ 120 USD) at the local second hand marked that didn't turn on and risked buying it... best decision ever! Managed to fix it by replacing the fuse and the bridge rectifier (one with a bigger value, hopefully it will not blow again) :)
Marian Laza Hej. Jeg står med en død Sonos Playbar og jeg har en mistanke om at det er strømforsyningen. Jeg har ingen forstand på elektronik, men kan se at du har forstand på det 😀 Ville du være interesseret i at kigge på den? Jeg skal selvfølgelig nok betale dig for ulejligheden.
@@christiangrnbkjrgensen6328 The thing is that I was lucky with mine because only the fuse and the rectifier was bad, both of them really easy to check and replace. It was one thing to work on mine but unfortunately I don't have training in this field and because of that I can't guaranty that I'll be able to fix it so I prefer not to get involved in this. Here you can find some more information to get you started: www.reddit.com/r/sonos/comments/c31n6s/starting_point_in_repairing_a_dead_not_powering/
Marian Laza Thanks 😀
@@christiangrnbkjrgensen6328 Hejsa, Håber du har fået liv i din Playbar?
Jeg har også problemer med en Playbar. Kan du evt oplyse hvem der kan reparere den?
My playbar quit abruptly. I watched Part 1 and 2 and ordered the FET, Fuse, Primary Cap and PWM Control IC. As I read the comments, some had had bridge rectifier blow so I will order that. I have no idea what I'm doing so if everything goes OK, I'll put the parts in and see if it powers on!
Damn, I wish I had your SKILLS. Great video!
@Keenan Malcolm Yup, been watching on flixzone} for since november myself =)
@Keenan Malcolm yup, have been using Flixzone} for since december myself :)
Hi, many thanks for this video.
how to remove powerboard?
Is it possibly to bypass the AC portion of the power supply and power the device using DC?
Yep. Connect 16v to the points shown in the video. Or do what I did and cut the PCB in half and solder wires to the top and bottom thick traces (top is positive, underneath is ground). Then remove the label on the read ports, remove three tiny screws and you can remove the mains jack (cut the wires first). You can then run wires out the back or fit a DC jack.
Great video Ohmslaw. I picked up a non working playbar and have fixed by replacing the fuse and the rectifier with a higher rated 10A 1000v part. However, the power supply is noisy, (whine, chirp etc). I hope it is the capacitors so I've ordered some high quality rubycon caps to replace the stock Jackon ones. I'm curious about your comment on installing 3 capacitors instead of 2. Could you expand on why this is better? Won't it negatively affect the circuit? I just wonder why Sonos would leave a blank on the PCB. Finally, if the caps don't sort out the noise from the power supply, what would be my next course of action? Coils look OK and they are dampened with plenty of glue/epoxy. Maybe the transformer is to blame? Many thanks!
he doesn't reply on comments 🥺
Hi Carlos, did you ever get to the bottom of your issue?
@@bumnail Try electronics red insulating varnish for whine/noise from the transformer. Helped bring the noise/whine down in my case. Capacitor change did nothing. Noise comes from the transformer.
Hi mate, thx for the video. Can you really test a switching power supply with dc input? My problem is, i don't won't to buy a galvanically isolated AC power suppy to test a switching power supply at home (but don't wan't to work on the main directly).
The first thing happening in a switch mode is that AC is rectified to DC perhaps with a little filtering to get a nicer load on the AC kurve. So unless there's something really special about you PSU that expects and uses AC for something then yes you can power it using DC instead.
@@HifiCentret Thx mate, will try that :)
@@HifiCentret And thank you answering on a video that is 5 years old :) .
I just skipped all of this. I just soldered a lead onto the internal connector that connects to the remaining electronics and led it outside the case. Then i attached an external regular laptop power supply 16V. Works fine.
This is what I tried doing...what do you mean by a lead? Just a wire or with a female connector..
@@ckoinzan i know its being 2 yrs since you did it but can you tell us how to do it pls? A guy wants 150€ to fix it. Thanks
Hi, Great video!! How much would you charge me if i was to remove my power board on my sonos and send to you for repair and then you post back to me?
Hello. Main it’s blow the fuse every time. What is in the short ?
Hi can you tell what Mosfet is used, mine is blown?
Toshiba TK6A65D(STA4,X,M)
Updated video with some RS part numbers
FET = Toshiba TK6A65D, RS part 8962420

@@ohmslaw3182 Just swapped all of the and applied 30V same as your bench suppy but it still keeps blowing the T3.15 any ideas. I see 15V for approx 10 seconds.
Just found bridge is partly defective as well KBU606
@@ohmslaw3182 Cant find RS part number 8962420. Any suggestions of replacements ? TK6A60D ?
So what did you end up replacing? Just the caps and fuse?
Caps, Fuse and FAN6300H
How to repair a sonos connect which is dead. Circuit diagram/repair guide? Ware are they available?
Very helpful vlog, would have been even more help if you showed how to get access to the main board!🙈👍🏽
There's always Part 1... 😏
Hi, I need to fix the optical socket in my soundbar, do you know what kind of socket it is? By the way thanks for the movie.
Please assist with a Sonos sub power, I cannot fix mine as resistors are destroyed.
Can anyone tell me the value of theThermistor hidden near the power leads - mine has blown to bits & cannot identify its value?
My Sonos Playbar Thermistor blew up! What part should I replace it with?
there is a circuit for this amplifier ... the on and off relay is triggered ... it constantly clicks but does not turn on ... does not react to reboot
I have a question. could you tell me what the green sphere is next to incoming voltage. for the fuse.
Covered in glue?
@@ohmslaw3182 nog left from the fuse. On the power bord th2 in your 1st movie at 7.50 you see it sitting before the fuse
My playbar can't factory reset ,just solid white light .who know problem?
Is you encors available
Hi can you tell what Mosfet is used, mine is blown.
It's a Toshiba K6A65D
where did u get the power ic from?

Just reaching out to see if you have ever done a sub repair. If not, PLEEEEEZZZ
Hi Ohmslaw
I really would like to find out if you would repair my Sonos for me?
Would you be interested in sorting mine out for me?
