Yes, plastic cap off both ends and when inserting into the tv twist and locked, but it won’t lock in the sound bar. Doesn’t seem to lock and make contact in the sound bar? Sound did come out of the sound bar by pressing the optical cable into the sound bar only for a second, but didn’t stick and upon another attempt no sound. There’s light at the end of the cable so I know it’s connected to the tv? Digital port on the sound bar must be damaged.
