Set loses audio very intemittentely. May play a day or 2, then lose audio.
When it loses audio, can hold vol up or down and audio comes back while
button is pressed. When button is released, audio drops out again. Vol does
increase or decrease while buttons are pressed. Disconnected button assembly
at both ends. Problem still happens. No manual. Any suggestions? Thanks.
