This is another common issue with the Playstation TV. Most of the time it requires a system update to download new games and to save a game. Also, it could be an issue with the vita card located in the side of the device.

This is a common problem and can usually be fixed by checking the HDMI cable and making sure it is plugged in and making good connection with the tv and the device. Another solution to the problem is to make sure that you have the tv on the correct input that the device it plugged into.

Check to see if the batteries are charged in the controller and replace them if they are dead. Another solution may be that the controller may not be paired with the device. If this is the case then use the manufacturers guidelines to pair the controller with the device.
