My brand new Streambar either won’t power on or won’t send an output to the TV (can’t tell which one because there’s no power or indicator light to say whether it’s on or not).
I tried to setup on multiple TVs, multiple power outlets, and multiple HDMI cables with no difference in outcome (TV says no input detected). Both TVs were Sony and have HDMI-ARC inputs. Did I buy a lemon?
Sounds like you proved its a problem with the streambar by it failing on multiple tv's and with different hdmi cables. I'd return for exchange. Don't give up on the model.
