In this article, we will include the best solutions to resolve the no signal problem on your TV. Just keep reading this article till the end. Try every step mentioned below.
1. Check the Input
You must have connected some media source with your TV. For example, it may be a cable box, TV Stick, gaming console, internet, or antenna.
So, you need to ensure that your TV is connected to the right input or source. You can change source or input via the button on the remote or TV set.
Shift the source to AV>TV>Digital TV>DTV>HMDI (1,2,3), VGA, or Component. Wait for the signals to appear at each source shifting to find out the right input for your media source.
If you have connected an antenna or a satellite dish to your TV, move it a bit and fix where the signals appear. However, if these tricks do not work then try the next solution.
2. Inspect the Source for Any Damage
Obstruction, corrosion, and incorrect position of antenna or satellite dish can also cause the issue of no signal. It is necessary to check these signal carriers.
Make sure that nothing is placed near or over your antenna, dish. If an electromagnetic device is placed closer to a dish or antenna, it will interfere with the signals.
Hence, your TV will not display media. Moreover, rusted, damaged, or broken antenna or dish can also cause this issue.
Because they are exposed to heat and water, dishes and antennas are likely to get corroded. So, inspect them and replace them if they have expired.
3. Examine the Cables and Connections
Although you have plugged in everything yet your TV says no signal. Maybe the plugged-in cables are faulty. If you have connected your TV through an HDMI or Optical cable, examine them carefully.
If the cable is damaged, it cannot deliver signals. Usually, the cable gets twisted after constant use. A short circuit may also damage the cables internally.
Another possibility is that the cables are plugged in loosely. So, you need to consider all these points. Just disconnect all the cables from your TV.
Clean the connection ports and cable connectors thoroughly. Dust trapped inside the ports also causes a loose connection. Plug all the cables back in firmly. If any of them is damaged, replace it with a new cable.
4. Check the Signal Strength
Another reason for no signal problem is weak signals from the source device. For example, you have connected your TV to the Wifi router. It may not be sending signals or signals are weak.
Reset your Wifi module by turning it off and unplugging it from the power supply. After a few moments, turn it on. You can check the exact reset method in the user guide of your Wifi router.
Sometimes, due to system maintenance, internet signals disappear. So, you have to wait for their arrival and the temporary issue of no signals will be solved.
Also, try changing the password of your Wifi and then connect it again. In addition, connecting Wifi through Ethernet cable can also resolve the issue.
In case, you have connected a streaming device with your TV, check its performance. Plug the streaming device (Fire TV Stick, gaming console, cable box, set-top box) into some other TV or computer.
In this way, you can confirm whether the device is sending signals or not. It is better to reset, update, and reconnect these devices with your TV.
