Saw a TV repair guy in Sacramento use a bread tie on a customer's soundbar and I fixed mine the same night
I was at a small electronics repair place on J Street in Sacramento picking up a busted speaker when I watched the guy behind the counter tidy up a soundbar cable with a plain bread tie. He looped it twice and twisted it flat so it looked like a little knot, not a lump. I went home and did the same thing behind my own TV, and now the cords sit tight against the wall instead of drooping. Took me maybe 4 minutes with a bag of ties from the kitchen drawer. Has anyone else tried this, or do you use those little velcro strips?
