Hi Robert,
This is an issue with your console.
1.)Open your console and check all connecting cables, something maybe loose
2.)else it could be a chip failure, then you will need to replace the board. Typical console replacement may set you back USD $400 about.
Is the unit still under warranty? If so get them to repair it.
let me know if you need further assistance
