I have a samsung smart tv model UE46ES8000 with the latest firmware installed. Two days ago it started happening that when I vist the appstore on my tv, the icons wont load at all. I can see the text of the apps, but not the icons. I've tried plugging the tv out of the main socket, but that didn't help. What can i do to restore the icons in the app store? I hope I wont have to revert everything to factory settings. Thank you in advance for your assistance.
