Have an Emerson model lf501em5f . The sound cuts out every couple minutes after we turn it on. Have tried doing a reset on the TV and different devices and ports, still cuts out every few minutes. Suggestions? Thoughts? Thanks

That might be audio related circuit does not get enough power due to capacitor failure (used to store charge) so it’s capacitance decreases(then charges will be stored for few minutes/) but on another side maybe audio ic is multifunction.
