HW K430 soundbar continuously mutes itself

Matt48 — Wed, 07 Aug 2019 10:54:46 GMT

Hi,

A strange issue on my HW K430 soundbar that started this morning as I swtiched the tv on. The soundbar automatically mutes itself no matter what I do or what input I select. So for tv, I cycle to D.In, it then displays the volume level and the TV sound is coming through the bar but after it times out back to D.In it mutes itself and the only way to unmute it is to turn the volume either up or down, then when it times out again to display D.In it mutes again.

I've tried unplugging everything, tried a different optical cable that I know is working fine, tried it on another tv, same issue, and taken the battery out of the remote etc, but nothing helps, I still get the same problem. The hard buttons on the end aren't working either with the exception of the source cycle button.

If anyone has any experience or knowledge of this I'd be really grateful to hear about it!

Thanks in advance!

Matt

Yes! The issue with mine was the buttons on the side, or the ribbon cable connecting it to the main board. I never used them anyway so I opened it up, disconnected the buttons, and reassembled. Remote still works, issue resolved!

I’m having the same issue and the repairs are too expensive. How did you open it? Did you pry it from the sides?

If I remember correctly there was a lot of things just stuck on with adhesive. But I definitely just started pulling out all screws I could find, and print off anything that was stuck on with adhesive like the rubber feet or something. I don't think they're was (much?) Prying

Did you fix the problem yet?

if not then heres what to do:

remove the screws to open the back panal

there is a ribbon cable beside the where the power cable plugs in, disconnect the ribbon cable.

you wont be able to use the buttons on the sideof the speakers but the problem will be gone and the speakers will work fine.

Reply to Bozay: I have the KW550 soundbar (or similar name). I don't know how you figured this one out. But thanks, it worked like a charm. This saved me at least a couple hundred bucks for a new soundbar. Note: the manual control buttons on the end of the soundbar no longer work. But no worries. I didn't even know they were even there. Thanks again.

Amazing, followed instructions, removed 6 screws, no glue around the edge, so came off quite easy, gently pulled and unclipped the ribbon, re screwed the back and works absolutely fine.

Thank you saved me a few hundred pounds for a new sound bar, I never used the side buttons on the actual unit anyway.

Thanks again.

Paul

Meu soundbar k-450 estava sempre ativando o mute e os botões da lateral não estavam funcionando.

Quando abri o meu k-450 estava com a trava do cabo flat aberta. Removi o cabo e passei um limpa contato conectei o cabo e fechei a trava, resolveu o problema, todos os botões estão funcionando perfeitamente.

Try resetting the soundbar.

Turn it off with remote. When it's off hold the play/pause button for 6 seconds.

You should see >INIT>OK.

Youre good to go

quickly unscrewed my sound bar and disconnected the ribbon mention, as I was having the same issue, works like a charm. Now my sound bar doesn’t go on mute every time I try to turn up the volume on my remote. Thanks!

Same solution for my HW-K39 worked great. Ribbon cable was a bit difficult to remove but problem solved once disconnected. Thanks!

I have the same exact issue so frustrating. Why is samsung not doing a recall on this? This is unacceptable why should we have to dismantle a sound bar and unplug anything to make something work. I am scared to take it apart worrying that I will break the cover or something worse. Tried the resetting sound bar no luck.

I am a female and not any good at this stuff but I will try just nervous that I will break it and then does not work at all.

Anyone have "specific tips" on which screws to remove and how to pry it off? Is it glued on? Are there any tabs I have to worry about breaking? If so can you tell me approximate placing? Best way to remove wire without damaging something else? One stated it was tough to remove the wire. I am hoping I am strong enough to get it off. If not could one use pliers or some tool to assist or is it to dangerous to accidently damage other components?

When you remove wire, the end side buttons do not work which is fine but does the front light that shows input, volume on etc still light up-work?

Again, I am nervous as I do not want to break it as cannot afford to replace it 😕 but with tips, I will feel more confident and will go for it. Thanks for your input in advance.

Are you saying it's the hdmi causing the mute to continuously come on? I am curious. I think I am using the other connection not hdmi and I am having the same problem as the others. I guess I have to take it apart but if it fixes it great.
