We too have this issue with all three of our television sets. I believe we might need to go with a different company receiver like the Amazon fire stick or Chrome cast because it doesn't seem fruitful to replace all three wires at $60. And with the part on back order it's not even possible.
This is most certainly a defect with this Roku device and as I pay for the Roku service itself I'm very disappointed 
I also have this problem. End of long range wireless receiver cable failed from hanging due to gravity.

I would appreciate if you could send me a replacement cable.
I also have this problem. My long range receiver cable broke on its own and now I can't use my Roku, and the replacement cable is backordered for months and months. I'd like a replacement cable :)
