I have a UN55MU630D (firmware 1290.3) and the available memory is stuck a 0 KB. There are several issues that appeared because of this:
- Volume control not working
- Unable to save settings (e.g. changes in brightness, sharpness, etc)
- Unable to download new apps
- Unable to update existing apps
Among other things, makes it appear that the remote is no longer working, but in actuality it's the TV not responding to it. I am at a point where the TV does not immediately respond to the remote, except to turn it on.
One way I'm able to get to the smart hub is when the TV first turns on. If I need to get to it again, I hold down the "home" button for 10 seconds to bring up "remote management". Cancel "remote management" and the smart hub appears and I can navigate with no issue - so I know the remote is fully functional. Outside of this, the TV doesn't respond to most remote control commands.
To turn off the TV I need to hold down the power button and the TV restarts. For about 5-10 seconds when the TV first turns on it does respond to the remote (so I can adjust the volume), but I can also turn off the TV.
Overall, nothing I have been able to do can clear the memory of the TV:
- Factory reset
- Smarthub reset
- Deleting apps
- Updating firmware (seemed to accelerate the problems)
When I started deleting apps I was able to free up a couple KB, but now all of the memory is used up again and all that's left are the built in apps which I can't delete.
There's no "clear cache" option for the apps and even with a USB stick installed I am unable to install or update any app.
So in the end, I need some kind of method to completely wipe the memory of the TV because factory resets don't do it.
I'm having this problem too. I was able to free a little space by deleting all of the delete-able apps, but like all other solutions, I expect it not to last.
Constellation said that you can install a USB drive, factory reset, and save updates and apps to the USB. I guess I'll try that next.
If the problem results from lack of storage, do you have any idea why it took three years? Is debris just piling up in there? I guess the factory reset really doesn't delete it all.
For over the first 2 years the TV was good, worked with no issues. Then a little over 6 months ago I noticed parts of the screen turning purple. Purple spots, I come to find, are potentially from overdriving the backlight LEDs by keeping the backlight to max. So keeping it between 10-15 has at least slowed the progression of purple (since it's out of warranty they won't cover this repair).
But it was also about that time I noticed that the volume control stopped working. I would see the numbers move, but it would then "bounce back" to the original volume and never change. I did the usual which was reset the remote (which never worked) and factory reset the TV (which worked for a couple days). Then I discovered an easier method of simply turning off the TV, waiting a couple minutes, then turning it back on frequently fixed it (but not all the time).
So I lived with a purple-spotted, volume-bouncing TV for a couple months, but also noticed the memory slowly reaching 0 KB even though I wasn't installing anything extra. I would delete apps or factory reset, gain some KBs, and the volume would work for a couple weeks. Then the available memory would reach 0 KB, delete the rest of the apps I could (or factory reset) and installed a USB drive. That worked for a couple more weeks.
Then this latest firmware arrived (1290.3), and almost overnight the entire TV became useless. Couldn't free any KBs, apps would not install after a factory reset, volume not working again. Then the home button and other functions stopped working when using the remote. Couldn't install apps even onto the USB drive, and, well, everything else I described in my original post.
So here I am, with a "smart" TV watching movies and YouTube videos on a laptop instead of my UHD TV. It appears my only options are to pay for repairs or get a new one...for a 3 year old TV.
It's been a week with no response, so I'm assuming the answer is "it can't be done". I would have thought there would be some way to wipe the memory and start fresh, kind of like reformatting a PC. Perhaps booting the TV off of a USB drive and wipe and install the firmware.
The odd thing is I'm having no issue with the volume now... go figure. No apps work, can't download anything, it doesn't save settings, and the TV doesn't immediately respond to the remote, but at least I can turn it on and change volume.
