Samsung TV Bad Power Supply Symptoms
An inadequate power supply can be damaging. It is best practice to ensure that your cables are correctly fixed to the primary power source, and it’s also essential to be knowledgeable about symptoms that your Samsung tv might give as a result of an inadequate power supply.
Knowing these symptoms helps you solve the problem using the right solutions and reduces your panic.
Here are some of the symptoms:
Tv Not Turning On
Have you ever tried to turn on your TV, and it surprisingly let you down? Then your Samsung tv has been thrown off balance by either an insufficient electric current or a faulty/loose cable connection. When Samsung tv power on-off problems occur, it is usually a pointer to a faulty electric connection in your home and has nothing to do with the television composition.
You should perform a soft reset on your Samsung tv by simply unplugging the cable from its outlet. Leave it for 30 seconds, and then plug again. If the power outlet is in good condition, your Samsung tv should work.
You can try other power outlets in your home, and you’ll see the stand-by light come as soon as it gets into a functioning power outlet. Leave for another 30 seconds before pressing the power button.
Standby Light Off
The standby light simply signals that your Samsung tv is ready to begin its duties once you give the order by pressing the power button. But what happens if this standby light, usually in red, is absent?
If this occurs, you should know that an error in your home electric connection is responsible for the absence of your Samsung television standby light. Also, you should note that your Samsung smart tv standby light will occasionally be off when a malfunction occurs in your HDMI link.
Check that your TV connects correctly to the power outlets. Turn it off for a minute or less before plugging it in again. If the standby light is still off, you should try another power outlet.
Flickering TV Screen
Your Samsung TV might flicker if your cables are burnt, not correctly fixed to the power outlet, or damaged.
Sometimes, the flickering or freezing might be from the streaming platform, the internet, or the broadcasting network and has nothing to do with your power supply or connection. Other times, your Samsung tv flickering occurs because of your room’s lightning or external electrical interference.
Next time your Samsung TV flickers, you should check that there are no loose connections and that your power outlet is working.
Lines On the Samsung TV Screen
One of Samsung smart TV power supply problems is when you see lines appearing on your TV screen. Lines appearing on your Samsung TV screen might mean you have a low electric current, and you need to turn off your Samsung TV to protect it from further damage.
You should check your cable and HDMI connection if the lines sway and try to disconnect and reconnect the HDMI connection and cable to fix this error. Also, you should check your connection and verify that the power source is not malfunctioning.
Blank TV Screen
Once your Samsung TV goes blank, try a soft reset to help get it back on and running. The problem is probably a Samsung tv power supply issue; turning it off and disconnecting from all power sources and cables should do the trick. Leave your Samsung TV unplugged for a minute or two before you plug it back into its electric source.
You can also perform a hard reset on your Samsung TV by removing the cable from its power cord and pressing the power button on your remote for 30 seconds.
