Klipschguy45

My klipsch cinema 600 sound bar stopped working today. All of a sudden I noticed some crackling , no sound out of the left tweeter and one red dot light where the usual white LED volume dot lights are. It does still seem to connect to the subwoofer(I see it’s blue light turn from flashing to solid), and will play but only out of the right tweeter. I am now also unable to connect to my soundbar via the klipsch connect app. Any help would be much appreciated, hoping there is a fix as I bought it second hand and no warranty
