But good is not a bug but a feature, at least I'm moving now more. - To pull the plug ...
For firmware update: The automatic update of the TV via Internet search was unsuccessful, so look yourself and draw on NEN USB stick, then plugs into the TV (unzip before, is ne .zip folder and without the stick). Then start the menu and the update (should actually go of its own accord). Then wait. After about 10 minutes he was about 75% complete. Now moves 20 minutes ago nothing .... oO..das is probably not a good sign ...
