@ritz1234, Maritza, You did not state your model# so I will give a some what generic answer common to Vizio television with this issue. Try a reset, unplug the TV, then press and hold the power button ((on the TV set)) for 30 seconds, then release it. Then wait 10 minutes and plug the set back in, press and hold the power button again on the set until it turns on.
No go, probable memory on the board has failed. EEPROM memory may have to be replaced or the main board. Links below may have some more helpful info. on your TV's problem. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
