Blue and red blinking subwoofer hk450

Resetting works for a bit then just keeps going back to the red and blue blinking light

The red and blue blinking light indicates that the Subwoofer has lost its connection to the main unit. Follow the connection guide on page 17 of the user manual here. If this continues, it could be that a software update of the main unit is required.

Let us know how you get on.

I have a similar issue with samsung soundbar not connecting to there subs. It's really common when you google it. You can buy an random bluetooth speaker for a few quid and connect it to your phone no problem yet samsung have issues connecting there own devices.

Hi @John_C. Do you have the same model?

@Mitcnath, are you still experiencing this issue?

I've got the model up HW MS 550 with your top of the range sub SWA-W700. Which due to the connection issues turned out to be a massive error.

Have you connected the wireless dongle to the soundbar, @John_C? Pages 7 & 8 of the attached PDF will provide you with more info.

Hi, I have a HW-J651 soundbar and a PS-WJ651 sub, and the sub keeps doing the same thing, flashing blue and red.

It worked yesterday for the first time in about a year and then went again. I spoke to Samsung and unfortunately they were of little help. I'm going to ring my local service centre tomorrow, failing that, a facebook plea to anyone locally to me who has experience with bluetooth connections wh may be able to help. I'll keep you posted!

My Subwoofer will not stay on blue. I unplug the Subwoofer and the blue light comes blinking and goes back to red

It connected about 10 seconds the way I followed the user's manual but still disconnected after 5-10 seconds and the blue and red light blinked again.!

Hello friends, anyone resolved this issue? I have WJ7501 curved soundbar since about 6 years and it was working good until this morning when solid blue light turned blinking blue and red. Re-connecting helps for seconds, the main unit and subwoofer are next to each other, I even place them directly next to each other. Would updating firmware help?

Hi,

The same problem here. I updated the firmware, not solves. So I plugged in the power cable from the subwoofer to the same switch with the main unit. Now its closer to the main unit. Works for me. Red Light isnt flashing. Maybe its work

Best regards

This is a very shi*ty problem.

I spent 500 USD in a HW-Q70T soundbar + rear speakers and it happens a lot.

After many hours lost trying different things, what seems to work is to unplug the TV from electricity (Soundbar still connected). Disconnect subwoofer from electricty. Wait 10 seconds. Connect subwoofer. It will link to soundbar (but no sound since TV is off). Then turn on TV, and the subwoofer remains linked.

This is a very annoying issue - my Samsung R7 speaker flashes a blue light, then a red light - and constantly loops - it does not connect with any device! Anyone resolved this or know what is causing it?

It turns out it wasn't the workaround. I don't know what a workaround is for this.

Sometimes it won't connect. Then I unplug everything and let it rest for 10 min then it connects the subwoofer.

Could this be related to current voltage? idk... I don't know what else to think of

Hi, I finally got some help from Samsung. Their audio engineer said its a fault with the main PCB and this part is no longer available...basically it's useless now!
