👥 Here’s what one Reddit user had to say about it:

“I have the same problem with my VIZIO SB3651-E6 soundbar. It appears that after an hour or two of viewing TV with no changes to the volume level, it simply shuts down. This model includes a remote, and I ensured that the ECO mode was turned off on mine. It still happens after long periods of viewing.
