Even tho this repair was not a success, it highlights problems of trying to do your own board level repair in this modern era, and that is value in itself. We should value repair, or else junk will burry us.

For anyone stumbling upon this page, replacing the 330uH inductor on the logic side fixed mine. I had a constant high pitched screeching noise that devolved into a high pitched screeching noise and no boot up. after replacing the inductor, the sound bar started booting again and works. if its left off, itll screech for a while (probably charging up power) but this sound goes away. imo, turn off eco mode for this.

This was my problem too--- getting bad coil whine from the 330 inductor. No one else could hear it but it drove me crazy. Parts are available on ebay/amazon. This video shows the same issue. kzread.info/dash/bejne/q6h5p7CYc8-3XZc.html

Me too, exactly the same model and same problem at 13 months. I own two other Visio sound bars of different sizes which still work. You saved me the pain of trying to DIY. Other than this failure, the biggest issue I have with Visio sound bars is volume adjustment. For me, the volume increments are too wide, so either the volume is too low or too high. Annoying. At this point I'm not sure what to do. I knew from buyer comments that this might happen - and it did, so I was warned but kept going anyway. The low price got me. Maybe next time I'll opt for the warranty. For Vizio products, that's a good idea.

I did the same thing as you... I had mine for 5 years. I made a custom bracket. Took the time to clean up the wiring. Hooked it up and played Bluetooth music today, at low volume levels. I went to switch to the TV input and she was dead. No LEDs. No smoke. No noise. It has 24V DC on the output of the power supply board. But there seems to be a direct short on the logic/amp board.

"... This call is recorded for documentation purpose!!!.... " It is awesome.

I know this video is 3 years old, but I was having the same issue and here's how I fixed it. I can't gaurentee this will fix other people's issues, but it solved mine. I have a Samsung 7100 series TV with a vizio 5.1 soundbar plugged in through HDMI ARC. I had the same issue where my soundbar would not turn on. I got so fed up I actually went out and bought a new soundbar. Low and behold, exact same problem with the brand new soundbar. Made sure everything was set properly (cec was turned on) and could not get soundbar to turn on. So here's what I did that solved the problem. On my TV the hdmi 3 is the arc input. On my remote I hit source which brought up hdmi 1, 2 and 3. I went over to hdmi 3 (arc) hit the edit button and assigned "home theater" to the hdmi 3 input. This seemed to "turn on" the arc input and I've had absolutely no issues since doing this. The soundbar turns on and off with the TV now. I hope this helps someone. I'm not super tech savvy, just telling you what fixed my issue

Had the same problem with the same exact model. Happened about 10 months into having it. Pisses me off that it did not last one year. And the hassle of returning it, waiting for it to then probably burn again it not worth the hassle. No more Vizio for me. I spent a lot off time looking for a sound bar, I was happy with the sound so I was hesitant to throw it away. This video helped me move on. That woman had no clue how to help you aside for saying we replace it. $400 dollars down the drain. NO MORE vizio for me.

Army Parrot are you planning on getting a new one from a different company

I’m having the exact same issue. I took mine apart too but no idea what to do to fix it. I’m just as pi55ed as you about that soundbar. It was expensive and just wouldn’t power on last night and now I know not to troubleshoot with vizio because they won’t help for non-warranty devices. Thanks for the info!!

Outstanding video Kevin! Thank you

Yep same thing just happened to mine, same model and everything. I've owned this pos for 3 months and now it won't power on. Thanks Vizio.

I plugged mine in a 220V output. Your video was very helpfull! Hopefully, I'm gonna be able to remove this power supply board, replace the fuse and everything i gonna be alright.

Same problem here. I took it a few steps further and found the root cause to be an open winding on the primary (D1) side of the oscillator transformer. Unfortunate that Vizio can"t get their act together for a simple replacement power supply. The sound bar sounds really good when its working (with an external 24VDC 5Amp power supply).

Same thing happened to my Sound Bar and it is out of Warranty - power supply 24V DC reaches the logic board. I was able to test the individual speakers out as well. All the current Chinese and Korean TV AV makers have this problem of throwing mostly good items away v/s repairing it. I work for Amazon and I am going to take it personally to get this changed via amazon prime certified repairable items. This needs to stop.

Thanks for doing this so now I don't have to. And I probably won't be purchasing a Vizio unit to replace it since mine is only 2 years old. This is sad to me too!

great video thanks. I also have the same problem

Thanks for the helpful upload.

Same thing happened to me! Insane honestly I junked mine and got a Yamaha lol

Hey Kev. Nice video. It helped me to open out my sound bar. Did you get to know where we can get the power control board for this unit exactly?

Wow - Nice catch at 2:25 !

I used to manage a repair shop years ago, that's one reason we quit the business. I ordered a diagram for a tv one time and it cost $40. Probably many of those are custom made parts that you can't locate anywhere.

Nice video love the setup thanks for the info like you said they have the parts but they rather you spend more money 💰 rather then repairing your own times have changed for the worst when buy appliances 😡

Did you try testing the capacitors? C21 has been known to go bad without signs of flaring.

I have the SB-4551-D5 -- worked for almost 4 years, then an outage during the recent storm appears to have done damage to it. When I plug it in, one white light in the bottom left corner comes on, but that's all I get. No sound, no response to button (on soundbar) or remote control presses, so I am not able to perform any sort of reset. What bugs me most is that the subwoofer and rear speakers, which I absolutely love, probably still work, but 2 separate support people told me to just get a new one. I don't quite have the technical/electrical know-how to verify whether or not it's even possible to fix on my end. Not sure what to do...any recommendations??

i have the same issue but seems mine has do DC voltage on the secondary transformer on the power board. i can get a 120ac but cant seem.to find dc voltage. any idea? im just starting with electronics so, pls explain it barney style. thanks.

Hello, Would the sub pair with a bt transmitter ?or is there a way to convert the output to input ?

Mine worked fine last night now it won’t turn on. Had some storms so may have had a surge that shorted it. Idk. But I agree that we should be able to just get it repaired or order parts or take it to a 3rd party repair but they just make them to be pitched once they break.

We had this monitor come into our shop one time, I called the company for parts and they said you have to box it up and send it to us for repair, this was a heavy crt monitor. finally one of our customers was able to call overseas and locate a part for us.

hey guys,, i have a JBL SB400 sound bar and all of the sudden,, tweeters wont sound anymore... im guessing it could be either crossover issues or both tweeters burned out... got any idea on where to get them... both tweeeters and crossovers??? thks

I bought the same model in an auction, but it is completely dead, no LEDs come on when I plug it to power and press the power button. My PSU card was also good. Could not find the culprit part either.

I got this system as a Christmas gift. Unfortunately, being super busy and in and out of hospital, today (Aug 30) is the first day I've been able to set up the system . Guess what? Does not power on. No lights, no sound, nothing. Called Vizio and explained my problem. They asked me to UNPLUG the soundbar and hold the power button for 5 seconds (????). Then plug it back in and try the power button. Well, surprise, still nothing. Asked me for the serial #, and told me what store it had been bought in but said they would need a receipt to help me. WHAT??? Obviously they know where it was bought and when, so why need a receipt? And after this long, I'm sure the gift giver no longer has the receipt either. Said I'd have to buy a whole new system because they don't sell separate components. Now I'm looking for just a soundbar; trying Amazon, etc. Did find this for you though: vizpartsdirect.com/category.php?belongTo=5886&type=p Actual main boards, power boards, speakers, etc, for the soundbars.

I recently garbage picked a perfectly good looking Visio bluetooth soundbar with bluetooth subwoofer. Tried finding parts and after reading some forums I found out the same thing. Not available. This one powers up and looks like it works, but no sound. Frustrating.

i have a Samsung HW-MS650 but the grille has a dent in it :( I would like to try and take it off to fix it myself but I worry about breaking it

Mine(a different model with a sub woofer and rear speakers included)actually made it to 4 years... I turned it off one morning a week ago and tried to power it up after about 10 hours. Wouldn’t power back on. Took it apart but after watching the video and reading the comment just now, I’ve decided to trash it. Not worth my time and money to troubleshoot the POS!

Just to clarify, the power supply provided 24v to the amplifier board? ive got the same unit, and was thinking about modifying it to except rechargeable lithium batteries. I appreciate your making this video, only info anywhere that was useful, and i wasnt gonna open it without some kind of verification that nothing too complicated was in there. kudos complicated

Hi kev.just want ask u if it's possible to pair 2 vizio sb3651 eb subwoofer to one sound bar?

Any ideas on how to fix a right speaker that stopped working?

Have the same model. It died after two years same problem. Won’t power up. Guess i will disassemble and see if the ps is the problem. Thanks for trying!

totally agree with Robert H, i have a dead SB3851 just out of warranty and out of luck. I probed around the main board and found that none of the low voltage supply busses showed any voltage. The wireless module and ST main IC were both without power. The power supply board measure a constant 24 V.DC so that board looks good. Without schematics I'm just poking around blind. Looks like a common issue/design flaw. Anyone else have any luck with these boards?

I feel like I've spoken to that same rep for every other customer service call I've ever made lol

mine blow up when crossing the power supply wires when they cot work. by accident just come here to see how is a power bar is to be opened great video thank you. very informative I content open my z5iisound anyone know how.

I was surprised to see you with anything Vizio, ( knowing what you know about electronics ) but then you mentioned it was a gift.

I have a Vizio sound bar 5.1 but my subwoofer speaker is damage, how can replacement? The subwoofer speaker I think is stuck with glue

keV had me laughing for a second traying show us how to repair the soundbar he almost destroyed the soundbar by nearly letting drop lol

If lights are on but nobody home, that rules out the amplifiers, speakers, and anything on the output side. Probably the input switching chip is done, or else something on the input side of the DSP section.

I know this is a very late reply, but laws were changed to allow people to repair their own items and obtain parts.

What size are the speakers?

Mine finally gave out. Worked great for 3 4 years. Voice stopped working so I thought I'd power cycle it. No power after plugging it back in. Want to buy a new one but after hearing so many of these vizio bars having the same issue I don't know if I can trust them anymore.

After one year don't expect any help from the manufacture.

I got the same answer; can't be fixed, can't get parts, go buy a new one. When I do it won't be Vizio.

Mine stopped working today. Powers on but ZERO connectivity.

I have the SB36512-F6 and just died. Of course they have the schematics of ALL their stuff! That's how they get them produced. But making them available would cost a bit and stop you from purchasing another. I too, will never purchase another Visio product. Time to try a real name brand and see what happens.

My would try replacing the actual amplifier chip and see whats up

Remote stopped working, reset procedure won't help anymore. It's strange because it kinda degrades with time.

My sound bar has no passive radiators. How sad?

Model #SWA16 has finally stopped working - press power button after one second the first light turns on but no buttons are working and neither does the remote. Vizio has me power cycle and hard reset and nothing but the same issue. Customer care told me to throw away and repurchase . Lol really it’s only 5 years old. I’ve tested the power supply cord with another cord -same issue one light powers on. Subwoofer 🔊 is powered in as well and connected - no I don’t have it on mute - none of buttons have responded. This throw away society is driven by choppy engineering and consumer based corporations that pocket the exponential sales on products that don’t last. Cheaply manufactured- great sounding-but no longevity.

I find the whole idea of throwing away any electronics when the fault may be very small annoying, as a technician (telecomms / radio / TV / Satcomms / fibre systems / computer) and Amateur Radio Operator this goes against the grain. As I am retired from the workforce I get so many cries for help to fix things most of the time I can repair the things presented to my desk but suppliers of speakers and other consumer electronics do not care and live in a throwaway mentality. Yes this ham actually goes down to component level if needed with computer motherboards etc. I do enjoy your videos keep them coming. Cheers from Perth (Western Australia)

Do not buy a Vizio Sound Bar. The sounds just stops. Then you are left with a piece of worthless junk. Vizio will walk you through resets that do not work. Then they will offer you a 25% discount to purchase another Sound Bar. Why would one want to purchase another Vizio when they stop working after a year and a half?

Soundbars are poorly made, they don't last. A good component 2 channel stereo will long outlast a television.
