HD THEATER SB 3 SOUNDBAR subwoofer has no sound. Blue light is on.


Recommended Posts

Sub is paired and connected to the soundbar. 

I have unplugged it overnight in the case of an internal circuit breaker for the amplifier. 

It's worked flawlessly for the past 9 years. 

Anyone have any thoughts? 

Does the factory hole on the rear of the sub have a reset switch? 

Thank you in advance for your time and effort.
