Three days ago I upgraded to X1 and am now having issues.
The video/audio feed periodically (and simultaneously) turns on and off intermittently - sometimes as long as 4 seconds at a time.
It also occurs in relatively rapid sequence making it quite difficult to follow a program.
The video/audio also turns off with the message "Unsupported signal. Please check the device output."
My TV is a SONY Bravia KDL-40EXL401. What do I need to do to fix this?
Thanks for any assistance.
