Has anyone had this "About this TV" screen repeatedly pop up without clicking anything to trigger it? It pops up and then an automated voice recites the status code 00200000000. Sometimes it goes away after a minute but sometimes it causes whatever is being streamed on the tv at the time to repeatedly pause and unpause quickly and even keeps us from being able to power the device off. I haven't been able to find anything online about the issue.
Are you still having this trouble? If so, could you provide the full model of the television and a picture of the screen?
Have you done a Smart Hub or a factory reset to see if that makes it disappear?
I have the same problem on Model Number UN43NU6900. I installed the latest software (T-KTSUAKUC-1300.4) but the problem came back. I reset the Smart Hub but the problem came back. I did a factory reset on the TV but the problem comes back.
