The situation of TVs not being recorded even though they are connected to electricity and turned on is a common technical problem in many families. This condition can stem from underlying causes such as loose connections, incorrect signal ports, or can also be a manifestation of a hardware defect.
Taking initial inspection steps will help housewives save money to come up with a solution, saving time and reducing unnecessary repair costs.
Check power sources and sockets
The first step to checking when the TV does not display an image could be a power source condition. Make sure the power Plug works normally by trying to connect another device to the same Plug. At the same time, it is necessary to check the source line andplug it to see if it is loose or broken underground.
Verify controls and source buttons
Another reason why the TV won't appear when turned on may be due to remote control running out of battery or broken button. In this case, you can try pressing the source button directly on the TV body to check the device.
replace the battery with a new one or use a backup control if available. In addition, it is also necessary to check whether the TV is in another mode such as AV, HDMI, PC... which will be the reason why the screen does not display content.
Check signals and connection gates
The situation where the TV screen does not display images often occurs if the input is incorrect. On the control, you need to press the "Source" or "Input" button to move the correct gate corresponding to the connected device such as the output, drive, or gaming machine.
At the same time, check your HDMI or AV to see if your leg is loose or broken in contact. Some TVs also have the function of automatically switching to signal sources, so it is necessary to make sure that the peripheral device is turned on and working normally.
Restart the TV
When the TV is turned on without a screen but has an audience, it is very likely that the operating system is hanging or there is a temporary software error. To overcome the above situation, you should turn off the TV completely, withdraw the power source for about 5 - 10 minutes and then turn it back on.
With smart TVs, restarting the device will help the system refresh temporary memory, thereby fixing some errors such as screen black, stopping, or not displaying images.
If after checking all of the above factors, the TV still does not display images, it is likely that the device is experiencing a hardware error such as source errors, screen failure, or internal cable errors. These incidents require specialized technicians to check and repair them.
