A:AnswerSometimes, in order for a tv remote to work the soundbar, both remotes must be CEC compliant. Most smart tvs have a setting in the Settings menu under System to enable the CEC function. If CEC is enabled, then the tv remote will control the soundbar's volume and mute functions the same as the soundbar remote.
A:AnswerIf the light is blinking the subwoofer is not paired. I believe the correct sequince to reset the pairing is to press and hold down the button on the back of the spearker for a long time - like 30 seconds or more. Then on the bar, press and hold the power, source and volume plus buttons at the same time for at least 30 seconds. This worked for me and the bar and speaker have remained paired since I performed the factory reset. Hope this helps.
