How do I fix a blank or black screen on my Smart TV?

1. Check Cables & Connections: Make sure the cables connected to your TV and external devices (e.g., set-top box, Blu-ray player, streaming devices) are plugged in correctly.
2. Check the TV Power Source and Settings: Make sure your TV is connected to a working outlet and that the correct input/source is selected.
3. Unplug & Reboot: Unplug the power cable from your TV and any external devices, then plug them back in after 10 seconds. Reboot them all if necessary.
4. Update Firmware & Software: Make sure your TV and other devices have the most current software – updating this occasionally can prevent future issues.
