1. Wifi/bluetooth hardware already installed and enabled.
2. Wifi/bluetooth hardware already installed, but Bt is disabled in settings.
3. No bluetooth hardware whatsoever. Wifi only module is installed.
Since i have variant No 3, swapping the wifi only module with the right wifi/bt module would do the trick?
on ebay it cost about 20€. you have to open tv (very simple) and change it, then go to service menu and enable bt, bt services and probably you should change also wifi brand,depends on new chip (in wifi internal brands).
