Quick Answer: A “no signal” message means your TV isn’t receiving input from your connected device. Here’s how to fix it.
Check the Basics First
Select the correct input source. Press the “Input” or “Source” button on your TV remote and cycle through options (HDMI 1, HDMI 2, AV, etc.) until you find the active device.
Verify all cables are secure. Unplug and firmly reconnect the HDMI or other cables at both ends—the TV and your device (cable box, streaming stick, gaming console).
Power cycle everything. Turn off your TV and connected devices, unplug them for 30 seconds, then plug back in and restart.
Try These Solutions
Test with a different HDMI port. If using HDMI 1 doesn’t work, switch to HDMI 2 or 3.
Replace the cable. HDMI cables can fail. Swap in a different cable to rule out a faulty connection.
Check your device is on. Ensure your cable box, DVD player, or streaming device is actually powered on and functioning.
Update TV firmware. Access your TV’s settings menu and check for software updates, which can resolve compatibility issues.
Still No Signal?
If none of these steps work, the issue may be with your external device (cable box, game console) or the TV’s input board. Contact your device manufacturer or a TV repair technician for further diagnosis.
Most “no signal” problems are solved by selecting the right input or reseating cables—start there.
