I have had the above soundbar for just over one year and recently I noticed that the TV Screen (used as a centre speaker) was making a crackling sound every few seconds. I determined that the cause was that the ARC HDMI port on the soundbar was unusually loose (the other HDMI ports on the soundbar fit the cable tightly but the cable wobbles in the ARC port). I tried various things and in despair, I applied blue-tack around the cable so it would stick to the port and remain fixed. This worked for a while until the soundbar stopped completely. I removed all the blue-tack from the port but the soundbar basically does not work unless the cable is pushed in and held in a very specific position. Help is needed.
