The issue of a Samsung tv suddenly turning off every 5 seconds is one that’s been around for some time. However, the answer to the question, “why does my Samsung tv keep turning off?” may differ for each individual. If you’re having problems with your Samsung TV keeps turning off every 5 seconds or experiencing other issues, this article will help you find the solution.
Why does my Samsung TV keep turning on and off every few seconds?
There may be power issues with your Samsung TV, causing it to turn off and on randomly. The TV will turn off if it isn’t getting enough power.
More specifically, the TV power cables are almost certainly to blame for this potential power leak. These cables supply the necessary electricity to the TV; any damage will prevent them from functioning correctly.
It doesn’t have to be broken for power problems; if a cable isn’t fully inserted into a socket or a defective power strip, you’ll experience power issues.
Samsung TV Keeps Turning Off Every 5 Seconds: The Easy Fix
The following are some useful solutions:
1. Connect the TV to another power outlet
A lack of electricity is the most prevalent cause of TVs turning off unexpectedly. Possibly the TV’s power cord is loosely attached to the wall outlet. An additional possibility is that the wall socket is broken, only partially connecting power and thus preventing the TV cable from being plugged in.
Ensure that the cable is fully inserted into the outlet and firmly held. Unfortunately, your Samsung smart TV may still shut down every 5 seconds despite following these steps. It would be helpful if you tried the following fix.
2. Check the TV Power Cable for Damage
Your Samsung smart TV’s frequent shut-offs may result from a faulty power cord. Power fluctuations could turn off your Samsung TV automatically if that’s the case.
Check the TV’s power cord closely for any visible damage. Even if the cable seems undamaged on the outside, you should still run your fingertips down it to check for a break. If the power cord is malfunctioning, replace it with a good one to keep the TV on.
3. Power Fluctuations
Turning on your TV or other expensive gadgets when the mains power is unstable is not a good idea. Even though they use top-notch power protection devices, you should be cautious. If you suspect electrical problems, contact your local utility company. You will be notified if there are any power outages, and the issue will be resolved within a few hours.
4. Power Cycle the TV
If the electricity isn’t the issue, it could be the TV itself. There could have been an error in the onboard memory that caused the TV to shut off unexpectedly. You’ll need to power cycle your Samsung TV to fix the problem.
- First, use the remote or the power switch to shut off the TV.
- Wait at least a minute after unplugging the TV from the wall.
- Then, reconnect the power cord and switch on the TV.
- See if the TV turns off by itself after it starts on.
- If that’s the case, just keep doing what you’re doing until it works.
5. Disconnect All External Devices
A common cause of TV shutoffs is input problems from devices such as cable boxes and video games. Shut off the TV and reconnect all its inputs first to see if that solves the problem. You can also try connecting the gadget to a different input source to rule out a problem with the port.
A faulty input cable might be causing the problem, so try using another cable. In this case, it would be necessary to swap either the HDMI or optical cable.
6. Remove TV remote batteries
Samsung TVs that power off every five seconds may have a problem with the remote control. A stuck remote may force it to “push itself” rather than allowing you to control it.
Remote control batteries must be removed immediately so the TV can be rebooted. If your TV returns to normal operation, you may have a problem with your remote control.
So, you should open it and wipe down the inside to get rid of dust. Last but not least, press each button on the remote several times to release any button that has become stuck. The remote control should now work correctly.
7. TV Backlight Check
Make sure the backlight on the TV works. If the TV’s backlight is broken, the screen won’t display anything when you switch it on. The TV is powered on, but neither sound nor video is displayed, giving the impression that it is just dimmed.
Check that your TV is plugged into the wall and turned on. Shine a light on your TV after that. If the TV’s backlight functions correctly, it should be just the flashlight, and yourself reflected on the screen.
You can fix a malfunctioning screen’s backlight by swapping out individual led strips. However, a professional should be consulted if you cannot resolve the issue.
8. Heat the TV via the vents
If you leave your TV off for a long time, weeks or months, the capacitor could discharge or change the capacitance. The typical solution is to replace the entire board, which can be extremely pricey. In addition, this capacitor problem can result in your TV going off within 5 seconds of being turned on.
In this situation, a hot air blower is all that’s required. If your TV keeps restarting, check to ensure it is on and connected. Then, for the next 30-60 seconds, direct the hot air blower at the TV’s opening/vent, switch off the TV, and then back on again.
9. Check Hardware Connections
If the hardware components responsible for displaying images are faulty or poorly connected, Samsung TVs can suddenly shut down after 5 seconds.
“HDMI cable” refers to any cable used to output video on your TV. Connecting an HDMI source to your Samsung TV can cause it to shut down. Even Samsung recommends using only high-quality HDMI cables to get the best picture quality.
Non-approved HDMI cables may cause the screen to go black, making it appear as if the device has been turned off. Therefore, you should upgrade to a high-quality, approved HDMI cable.
10. Make Sure TV Isn’t Overheating
If your TV is overheating, it could malfunction several ways, including shutting itself off every five seconds. The most obvious reasons for overheating are a lack of proper ventilation and a malfunctioning built-in cooling mechanism.
First, make sure nothing is blocking the vents. Then, for optimal performance, put it somewhere that has adequate ventilation. Also, if you’ve been using the TV for a while in a stuffy room, turn it off and give it time to cool down. Finally, try turning on the TV again after about an hour to check if the problem is still occurring.
11. Fix Power Short in the Board
Cables connect a TV’s power supply board to its main board. Several cables are included, including PWM BLU.
By adjusting both the apparent and actual brightness, Pulse Width Modulation (PWM) is responsible for backlight dimming. The LED’s power is pulsated on and off to get this effect.
A faulty board could send the erroneous signal, causing the LED to pulse off and reduce the brightness of your display or cause it to go completely black.
Thus, you should temporarily cut the PMW BLU cable here. Then, access the TV’s menu settings and perform a factory reset. When the PMW BLU cable is reattached, the system will operate normally.
12. Inspect for Damage to the Boards
- Check the motherboard and power supply board for apparent signs of damage.
- Electrical board failure
- Power supply problems caused by faulty capacitors
- Fuses blown
13. Contact Samsung Support
If none of these solutions solve the problem and your TV still turns off unexpectedly, contact Samsung immediately. If you contact the store from which you purchased the TV, they will point you toward superior customer service. Samsung will send a specialist to inspect the TV and have it working again within a week, depending on the nature of the problem.
