I'm very sorry to hear that has happened. In order for me to help you most accurately, please provide the complete model code for this device.
So,the other day i decided to change my Samsung tv 's wifi settings, but for some reason the tv will start searching for a network and for maybe 1 Second will show the available wifi networks before closing out of the application completely. Obviously this makes it impossible to select a network let alone change any settings. If anyone has any ideas as how to fix this i. All ears. Thanks in advanced
