Getting really frustrated and need some guidance. About a month ago, the mute indicator would flash but we still have sound. Daily rebooting usually made this flaw go away. But then the volume would get stuck. We could only move the volume up or down a couple numbers. Again, daily rebooting usually fixed it. And now, we have lost all of our apps. I have done may resets, and restarted the Smart Hub, but nothing has gotten the apps back. There is a screen that states I need to accept the Terms & Policy Set Up, but nothing happens when I try to set it up.
I am about to lose my mind!
I have stumbled across a solution. It's not a proven solution, but so far it is working.
First, I unplugged everything from the TV and unplugged it from the wall. I let it sit for about an hour. Then I created a flash drive with the newest firmware update from 1/14/21. I inserted the drive and ran the update. I got a pop up that said "No update available at this time". I confirmed I was on the most updated firmware - 1290.3. So I abandoned the firmware idea. Next, I hooked up a new ethernet cable and hooked up the HDMI cord to my Directv box. When Directv came back online, I noticed my volume issue had resolved. This gave me hope. Finally, I clicked on the update Terms & Policy setup. It errored out on the first attempt. I tried again. This time I was able to accept the terms. The next screen took me to the login to Samsung account. Finally, my information had been lost and I was able to log back in. From there I was able to set up my Smart Hub.
Not really what step did the trick, but here is hoping it works for everyone else!
I've had this problem for months and started the same way (UN55MU630D). Volume not able to change, mute symbol would sometimes appear (with or without sound). Now I can't download or even start apps. Factory resets don't help. I can basically turn on and turn off the TV, and that's about it. At this point I'm using my Xbox for my video apps, which defeats the purpose of having a smart TV.
Have you found any solution to this issue? I am experiencing similar issues and factory resetting does nothing. Would be much appreciated if you could share if you found a fix.
Do you have your tv plugged in a surge protector? Try unplugging for about 5 minutes then retrying directly into a wall socket.
