I have an envision television every 5 minutes of the tv being on a headphone icon appears in the top right corner of the screen and the sound turns off. If I turn the tv off and then back on the sound comes right back on, 5 minutes later same thing? What can be causing this?

Only a guess but the headphone jack may be damaged.
Part of the jack is a switch that opens when headphones are plugged in.
Will the TV operate correctly when headphones are plugged in?
