question Base Station Broken/Flashing red light?

[modular511]

It would appear I am getting the flashing red light error on one of my base stations, I got the vive setup from a buddy as a gift, because I have been in physical therapy, so playing some of my games with walking required was a no brainer! But it would appear from some troubleshooting, that my sensor is broken! I figured as a last ditch effort id reach out here to see if anyone has any ideas! Thx for any help/advice & I hope everyone has a good weekend!
