A: Make sure all cables are firmly connected to your television and your external AV sources. After you have made all connections, press the INPUT or SOURCE button on either the TV or the remote and choose the correct source. Make sure your cable, satellite, or set-top box is turned on. If these steps fail, try a different set of cables.
If this doesn’t work, reset all your connections. Power cables or HDMI cables can come slightly loose overtime and lose connection. Start by unplugging the power cable from both the TV and the wall outlet. Next, unplug the HDMI cable from the TV and your media player. Ensure that both are firmly plugged back in; this will reset the connections. You may also try fully unplugging the power from you media player and re-plugging it back in.
