Samsung tv keeps muting with symbol appearing on screen with any remote button pressed. Also the red power light was flickereing all the time. Tried reset & power down but no joy.
Hi I had this today and tried literally everything then I plugged our amazon stick into tv in front room went out for few hours come back to it doing same thing on that tv to .
i reset the re synced remote new batteries left tv off over night etc to no avail.
FIXED IT. For us it was the batteries in the amazon fire stick went dead and some how interferes with out tv.s so if you have same or something similar plugged in try new batteries in that remote
Mine too! I have spent the last two hours trying to resolve this issue, and finally turned to the Samsung community in desperation....such a simple fix, change the batteries in the Amazon Firestick remote and voila, all is restored! Thank you.
