Why Does My Samsung TV Keep Restarting?
There are several reasons that may cause one’s TV to restart and, in some cases, to reboot as well.
Let us go through a few of the most common causes for the restarting and rebooting problem.
Damaged Main Board: Unfortunately, if there is significant damage to the motherboard, the only viable solution would be to replace the faulty board with a new one. In this case, you cannot fix it with alternate solutions expressed in this article.
Blown Capacitors/Damaged Power Supply: In this case, important parts of the TV will need to be replaced and checked and therefore should be taken to a servicing outlet to prevent other original parts from being affected. You should not attempt to fix the TV if you do not have previous knowledge about the television’s electronics.
Damaged Flat Cable: If the flat cable that is connecting the Main board and the LED control panel is damaged or looks burnt, it would cause your TV to restart.
Samsung’s Chip overheating: The CPU installed in a Samsung TV can often overheat through the years. With time, dust accumulation can cause the TV’s interior to slow down. A quick and easy way to fix this is to regularly clean the TV in a safe environment. You should use a blower and do not use anything wet to clean the TV.
Outdated Software Updates: Sometimes, the TV needs to update its software and may restart due to insufficient internet connectivity. Therefore, it keeps restarting to finish the necessary software updates.
Loose Power Supply: Faulty wiring or switchboard may affect the television negatively. You need to check if the TV is getting an uninterrupted power supply from the outlet that it is connected to.
How To Stop Samsung TV From Restarting?
1. Check the Cables
Firstly, you need to check all the cables attached to the back of the TV to see if any of them look damaged, bent or loose.
Remove all the cables and then attach them properly. Make sure you use high-quality 4K HDMI cables.
Apart from this, as a precaution, you should also reseat the wires as dirt can usually get into the sockets, which causes the power supply to be affected.
Repeat the process by disconnecting the wires and reconnecting them to resolve the issue.
Tip: Get rid of all unnecessary devices connected to your TV, like USB sticks and unused streaming or sound devices. You can also try getting a new power cable for your TV. Avoid using surge protectors.
2. Update Software
The TV may be restarting because it is unable to establish an internet connection to update the software.
If this is the case, updating the software would eliminate this problem altogether. Follow the steps given below to learn about updating your TV’s software.
- Go to “Settings” and select “Support.”
- Select “Software Update”.
- Select Highlight Auto Update and turn it on.
- Select Software update.
3. Soft Reset your TV
Unplug your TV for 60 seconds and plug it back in. I mention this fix in many of my tutorials, it is so simple, yet effective.
Repeat this step a few times if it doesn’t work at first. Smart TVs can be stubborn at first.
You can combine this step with unplugging and replugging all the cables, as we mentioned before.
- Turn your TV off.
- Unplug it from the wall.
- Remove all the cables connected to the TV.
- Inspect your cables for any damage or dirt.
- Wait for about 10 minutes.
- Plug all the cables back in.
- Power on your TV.
Tip: Try disconnecting your TV from the power supply and leave it this way for a longer period of time, like overnight.
When you power up the TV, hold the power button down instead of releasing it for about a minute.
4. Turn Off Anynet+
This feature of Samsung TV is renowned for causing many issues, so let’s try turning it off.
- Press the Home button on your TV remote.
- Select Settings.
- Select General.
- Select External Device Manager.
- Select Anynet+ (HDMI-CEC) and press Enter on your remote control to turn the feature On/Off.
5. Disconnect your Cable Box
Sometimes your TV’s cable box might be stopping your TV from running smoothly or getting an important update. Do the steps below to rule out this problem:
- Disconnect the cable box from the TV.
- Turn the TV on.
- Perform a factory reset.
- Reconnect your cable box.
Also, make sure that all the cables of the cable box are properly attached and clean.
6. Reset Smart Hub
Resetting your Smart Hub can help to eradicate any software glitches that were causing your Samsung TV to restart. Follow these simple steps to reset it:
- Press the Home button on your remote control.
- Go to Settings.
- Select Support.
- Select Device Care.
- Select Self Diagnosis.
- Select Reset Smart Hub.
- Enter the PIN for your TV(default PIN is 0000).
- Follow the on-screen instructions.
7. Select the Right Source
Make sure to select the correct input device by clicking the “sources” button on the remote.
Select the source that you know is sending signals to the TV. Most of the time it should be set to a TV source. To do that, go to Settings>Source>TV.
8. Fix Overheated Samsung chip
In order to solve this issue, there is a heating chip attached at the back of the TV that can easily come off, which prevents the TV from overheating. In order to solve this, touch the area near the HDMI ports.
If it is too hot, that would indicate that the paramount is overheating.
In order to resolve this, open the panel behind the TV near the ports to check if the heating chip has moved out of place.
To solve this, peel off the sticker provided by the Samsung package, and it should solve the problem.
Regularly cleaning the TV from the back with a blower can also keep everything much cooler!
9. Fix a Faulty Sensor
Sometimes your TV’s sensor can get faulty. If that’s the case with your TV, you can place a small piece of electrical tape over it and see if it will stop your TV from restarting constantly.
10. Fix the Damaged Mainboard
The main solution to a damaged mainboard is to replace it. Get it checked by a service center as soon as possible.
Some Samsung TVs often have a problem with a failed ‘NAND-IC’ chip. Sometimes it can also be a faulty Wi-Fi module.
But if you are tech-savvy enough and willing to go one step further, here are the steps you can do to try to fix the board yourself, provided you don’t have any issues with the mainboard that we have previously discussed.
Anyway, there is only one way to find that out.
- You will need to carefully unscrew all the screws from the back of your TV.
- Then locate your TV’s motherboard and disconnect all the cables and ribbon cables that are attached to it.
- Take the circuit board out.
- Make sure all the dust, if there is any, is gone and your motherboard is clean.
- Place the motherboard back into the TV.
- Make sure you plug all the cables back in properly.
Tip: If you don’t want to pay for a new motherboard, you can take your current one out and get an electrician to look at it, it might be cheaper than buying a new one.
11. Turn Off the Power/Sleep Settings
Press the menu button and switch off these settings from the “System” settings in the menu.
To turn it off, go to Settings>General>System Manager>Time>Sleep Timer>Select Off.
Moreover, Samsung TVs have a new feature called the “Automatic Power Down” which causes televisions to automatically go into standby mode if it does not receive any remote-control commands within four hours.
You may confuse this option for the TV restarting by itself.
12. Factory Reset your TV
You can also factory reset their TV, which will restore it to its original settings.
It will automatically reset all the settings back to the original ranges and would also delete data that may be causing the TV to crash or restart. In order to do this, follow the following steps:
- Open the Settings tab and select General.
- Select rest and enter one PIN or the default PIN 0000.
- Select Reset and press OK to complete the factory reset.
- Press the Menu button on your remote control.
- Go to Settings.
- Self Diagnosis.
- Select Reset.
- Enter your PIN( the default PIN is 0000).
- Your TV will now start a reset process and once it is finished, the TV will reboot.
