A: If you plug the game console into the TV usb port and find that there is no response, we have tested it and can conclude that the voltage may be different due to the different voltages in different countries. The solution we gave is not to plug the game console directly into the TV. You can try to connect the power socket to the phone's adapter (current 1A), do not use the TV as a power source. Q：Why does F-22 appear on the screen? A: Generally, F22 is displayed because the game card is not inserted properly. We recommend that you take out the card and insert it again. If it still does not work, please contact our after-sales customer service.
