Bad weather or hardware problems may result in a TV that doesn’t receive a signal, among other reasons. It is possible for your cable provider or streaming service provider to display an error message when there is heavy rain, snow, or wind in your area. The signal regenerates within a few seconds after you turn off a device. Most satellite dishes are designed to endure extreme temperatures.

In the event there is no hardware malfunction with the TV, then the problem usually comes from one of its many connections. The simple steps in this guide can assist you in resolving the no-signal issue without incurring excessive costs.
How Does a “No Signal” Problem Arise?
When the TV remote is turned on, many TV manufacturers have an automatic device detection and display system, which automatically detects and displays connected devices. If your TV says there is no signal, even though your cable box is set up as the correct input or source, you’re experiencing network reception problems.
The television can be turned off, waited for a few minutes, and then turned back on. Each connection has to be examined individually in order to troubleshoot it. Each connection should be removed individually.
You must disconnect the computer or laptop before connecting it to the TV’s HDMI port.

Windows 10 won’t connect when there’s no signal
There can be a number of reasons why you get the No Signal message when trying to connect your TV to Windows 10. Should you run into hardware-related problems, you can try a couple of things on the Windows software side, which will be covered elsewhere in this guide.

Some times you can switch the desktop to the HDMI port via the right-click menu on the desktop, while other times you have to do it through the BIOS (though it’s generally better to use the GPU port, as you will be able to take advantage of your graphics card’s capabilities).

Check the set-top box/cable box
If you are experiencing signal problems, it may be your set-top box. It is possible that your box will automatically update when your provider releases a new firmware version. Although the new satellite settings have been uploaded, the adjustments have not yet been applied to the device.
Unplug and reinsert the power cable to resolve the issue. The TV must be off before doing this. In addition, after the smart card or viewing card is removed, the cable box may need to cool down. Avoid applying too much pressure while removing the card. Embedding the chip facing down requires following any visible arrows after inserting the card.

Problems with HDMI cables/ports
Usually, an issue with the HDMI cables or the ports is the reason for a lack of signal. When the connections fail to fit tightly or slip out, a slight damage to the port can occur. In either case, you can change the HDMI cable or contact an experienced TV technician. Most modern TVs come equipped with two HDMI ports.
Once the cable has been disconnected, connect the HDMI cable to the old or new HDMI port. To make it easier for you to keep the HDMI cable in place, you may want to replace your cable with a self-locking one. The HDMI issues should be resolved in no time at all, and your TV signal will once again be working.

A cable box and TV sequence can be reversed if you are using an old cable box. By reversing the sequence, the devices will reconnect and receive signals again.
