Hi guys , my subwoofer has stopped working with my soundbar. There is power to the unit but no lights are on ( red or blue ) . The model number is PS-WJ650 . Has been working fine for years.

Any help would be great .

Hi @Danno72

Could we also take the model code of your Soundbar please? You can find this on a label at the back of the Soundbar.

Have you tried connecting the subwoofer manually? Have a look at page 14 of the user manual here.

I have . No lights at all on subwoofer. No standby or link. I've tested the power cable and it's fine. Seems there's no power within the unit.

Maybe a board problem?

Oh dear! It does sound as though it would need to be inspected by one of our engineers. Have a look at the following link, to see your repair options: https://www.samsung.com/uk/support/repair/

how did you restore power to the subwoofer? did you have to get the board repaired/replaced?

I’ve also got the same problem now, something popped and it stopped working. No sign or a damaged component and there is voltage across the fuse so that didn’t pop.
