If the software keyboard does not appear on the TV screen even when a text input box is selected, go to select the Leanback Keyboard in the Settings menu.
- Select Settings.
- Select Keyboard in the System Preferences category.
- Select Leanback Keyboard in Current keyboard.
If the software keyboard still does not appear on the TV screen, check if you have any wireless mouse receivers connected to the TV.
When some wireless mouse receivers (*) are connected to the TV, the TV may recognize those receivers as USB keyboards. In such cases, the software keyboard does not appear on the TV screen even when a text input box is selected.
Try to resolve the issue by removing the wireless mouse receiver.
