Simple Steps:

• Power Cycle: Turn off the TV and connected devices (cable box, etc.) for 60 seconds. Then, turn them back on in order.
• Input Check: Ensure you've selected the correct input source (HDMI, antenna, etc.) on your TV.
• Cable Tweak: Inspect all cables between your devices and the TV for loose connections or damage. Disconnect and reconnect them firmly.
• Cable Swap: Try a different cable, as worn cables can cause signal issues.

Advanced Troubleshooting:

• Reset Mania: Perform a power reset on your TV by unplugging it for 2 minutes. Some TVs have a dedicated "reset" function in the settings menu.
• Source Isolation: Connect another device (laptop, game console) to the same input on your TV. If it works, the issue might be with the source device.
• Service Check: Contact your cable or satellite provider to confirm no service outages in your area.

Bonus Tips:

• Check for firmware updates on your TV, as outdated versions can cause signal problems.
• If you're using a splitter, try connecting the source directly to the TV to eliminate it as a culprit.
• Consult your TV's manual for specific troubleshooting tips and error codes.
