My UN82NU8000 (about 14 months old) recently started having the picture fade to black (sometimes just a straight cut to black). When this happens all other functions of the TV seem unaffected (audio still works, WiFi is still active, remote still functions, etc)
I've tried various sources, cables, and Smart Hub apps (to eliminate faulty cables or sources), updated the firmware, and nothing seems to help.
Powering off the TV and back on again restores the picture, but it will again fade or cut to black after a few minutes. I should also add the timing is not consistent. Sometimes it's after just 2 or 3 minutes, sometimes as much as 15-20 minutes (but it goes black every time the TV is used).
Until now I've been extremely happy with this TV, so I'm hopeful there is some hope of solving this issue.
Any help would be greatly appreciated.
Which software version is running on the television currently (go to menu > support > contact Samsung to see that)? Do you recall seeing any error messages on the television?
I would suggest toggling the eco sensor settings because that could be why the television is randomly going dim.
I've tested both with the eco sensor on and off (as well as all other enegry-based options in the menu) Always ends up fading to black, and gets faster with it's cut out the warmer the TV is.
For example, first thing in the morning (after being off for 10+ hours) it'll stay on for 5+ minutes before it fades out. If I try again, maybe 3 minutes, until finally not being able to stay on for more than a minute.
When on, the picture is still great. I have to imagine it's hardware failure at this point.
At this point, I would like to have a technician out. Could you send me a private message with the full model and serial number http://bit.ly/2ihPL97
