Sub woofer not working

[Danno72]

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 guys I have an update on my sound bar. I now have power to the subwoofer but no connection to soundbar. The red and blue lights both blink when powered, I have tried to update using USB, the sounbar says no files , not sure what else to try, any ideas welcome
