VR Headset: Valve Index

I have enabled the Direct Display mode but the headset just keeps saying it's disconnecting and reconnecting every few seconds and then it goes into red light mode. I was using the beta for steamVR
correction its not displaying on the headset
I have had my headset for a few years and are not sure how long the waranty is for the Valve Index.
