Why Does My Samsung TV Keep Restarting?
1. Cable Between Power Supply Board and Main Board Shorting
One reason as to why you are having issues with your Samsung TV failing to work is because it keeps restarting or as to why it just randomly restarts a couple times while you are using it is because the cable that exists between your power supply board and your main board inside of your Samsung TV keeps shorting.
This cable is called the PWM BLU Pin and is what causes the dimming of the backlight inside of your TV. If this cable is not properly connected, these restarting issues can occur and even many more. Thankfully, this cable can be easily reconnected in just a matter of minutes from your own home.
Fix – Disconnect PWM BLU Pin (this pin causes dimming of the backlight) From Power Supply Board to Main Board
If you are having problems with your Samsung TV restarting at random times and not functioning at all because it keeps restarting, you’ll need to disconnect your PWM BLU Pin from the power supply board and into the main board.
2. Flat Cable Damaged
How to Spot It –
If your Samsung TV keeps restarting at random times or maybe will not even fully turn on because it just keeps constantly restarting, this may be because you have damaged your fat.
This just means that one of the cables located inside of your Samsung TV has become loose, unplugged totally, frayed, bent, or just straight up broken.
This cause’s fix requires you to be able to identify that this is in fact the problem, so there are a couple of other indicators on top of the Samsung TV restarting that can help you figure out if damage to your fat cable is the cause of your issues or not.

3. Samsungs Chips Overheating
How to Know –
If your Samsung TV keeps restarting at random times or maybe will not even fully turn on because it just keeps constantly restarting, this may be because your Samsung TV chips are overheating.
There are a couple of different signs if this is happening to your Samsung TV. The first is that your Samsung TV is stuck in a perpetual state of restarting because it is too hot. Another is simply that when you touch your Samsung TV, it is incredibly hot and painful to leave your hand on it.
If your Samsung TV keeps shutting off and fails to turn back on after these shut downs, this is another good indication that your Samsung TV chips are overheating. While this damage can sometimes be permanent, there are a couple of ways to let your Samsung TV cool down as well.
Fix – Wait For It to Cool Down
Your Samsung TV chips might be overheating, so it will not actually turn on fully and this is why it keeps restarting. Think of this issue like your phone.
If you are outside on a hot day and using your phone, it will start to work slower and you might even receive a message saying your phone will not work until it cools down.
This is the same with the Samsung TV even if your Samsung TV is indoors and in a climate controlled area that is plenty cool. If it is too hot, it might not be able to work.
If your Samsung TV is not turning on because it is overheating, just give the Samsung TV an hour or two to cool down and then try to turn it on again.
By simply just feeling the Samsung TV, you can tell if it is at a workable temperature or not. If it is just barely warm, you can try to use it but if it is hot to the touch, wait longer. Unplugging everything from it as well as unplugging your Samsung TV from its outlet will help this cool down happen faster.
4. Software is Out of Date
Fix – Update Firmware
Your Samsung TV may be working on an outdated system that is causing your issue with it not fully turning on as well. Just like your phone and other devices you use, your tv also requires a system update frequently.
Thankfully, there are some easy steps you can take to get your tv updated, and hopefully, your Samsung TV working as well. There are two ways you can update your system, on your TV or by using a USB drive and your computer.
If you want to use your Samsung TV directly, open up your TV and go to Settings. Once there, click on Support. Next, you will see Software Update and navigate to go there. If there is an update, you will have the choice to select Update Now.
Your Samsung TV will now update itself and need a couple of minutes to do so. Another way to update your TV is by getting a USB port.
Once you have a USB, go to samsung.com/us/support/contact and type your Samsung TV model code into the search bar. You will then see an Update File and will have to download that onto your USB drive. Now, take your USB drive and plug it into your Samsung TV.
As soon as you plug in the USB drive, your tv will automatically start to update. This will hopefully solve your issues with your Samsung TV restarting constantly.
5. Loose Power Supply
Fix – Plug In Power Supply Firmly
There are a lot of very simple explanations, as well, as to why your Samsung TV might not be turning on and just keeps restarting. Having your power supply cables plugged in properly is one of them.
Maybe you tripped over a cord and accidentally unplugged it or you did not quite push your power supply cord all the way in. Whatever the reason may be, your problems can easily be solved if this is the cause of your issues with the Samsung TV.
No reason should be overlooked as even something as simple as having your Samsung TV not properly plugged in can be the only reason you are experiencing any issues with the device.
This is easily fixed by simply just pushing in any of the power supply cables that are attached to your Samsung TV. Additionally, some of the power supply cables may be in need of a replacement as they are getting old and no longer working, or may have even bent or frayed beyond repair.
This means you might need to buy new power supply cables. One way you can get one is to reach out to Samsung directly and ask for replacement power supply cables. They will most likely offer to replace yours for free and send you your new power supply cables, but this can take potentially up to a few weeks for them to hear your problem and send you a new one.
You can also go and buy one yourself to get your new power supply cables in a much faster way. If you want to shop in person, head on over to any store similar to Walmart, Best Buy, or even Target.
Once you get there, go to the technology department and locate new power supply cables. If you are struggling to find power supply cables, ask the nearest worker to help you and they will give you a variety of different power supply cables that work with the Samsung TV.
You can also find one on Amazon, Ebay, or any other online store and get it shipped to your house. These types of HDMI cables range from $5 to $80, so you should be able to find one that fits your budget if you do not want to wait for Samsung to send you your new one.
6. Software Glitch
Fix – Restart TV
Restarting your TV, past the point of just turning it on and off, is another potential solution to getting it to fully turn on for you.
This first option is to unplug your Samsung TV from the socket it is located in. Once this minute has passed, plug it back in.
Now, wait a full minute, sixty seconds, and then go over to your Samsung TV and hold down the power button for thirty seconds.
Once this is over, start your Samsung TV back up and see if it will actually turn on this time and not just keep restarting.
1. Another way that you can restart your Samsung TV is by going to Settings on the tv itself.
2. Once in Settings, click on General and then find Reset. Click Reset and then you will need to type in your Samsung code that you created when you first started using this tv.
3. Once you have typed in this code, your tv will automatically restart. Now, you can try again to get your Samsung Tv up and working, hopefully no longer constantly restarting.
Fix – Unplug TV
Another option that is a pretty simple fx but tends to be overlooked is to simply just unplug your Samsung TV.
The easiest way to go about this is to just walk over to the outlet that your Samsung TV is plugged into. Once you have located this outlet, all you have to do is unplug the cord connected to your Samsung TV from the outlet you have located.
Once this is done, give your Samsung TV quite a while to just be unplugged and not be on or working. After an hour or even more, plug the cord back in to the outlet and see if your Samsung TV will now work without restarting.
If the outlet is very difficult to get to, you can also just unplug the cord from your Samsung TV directly. To make sure you are unplugging the right cord, simply just follow the cord from your outlet to your Samsung TV.
Once you have located the proper cord, unplug it from your Samsung TV. Again, give it a couple of hours, ideally, to be unplugged and fully turned off.
In both instances, the longer you leave the Samsung TV unplugged whether it be from the tv itself or from the outlet, the better for your Samsung TV.
After a couple of hours have passed, plug the cord back in to your Samsung TV. Turn your TV on and see if this stops your Samsung TV from constantly restarting.
Fix 3 – Wait For It to Stop
Another explanation as to why your Samsung TV is not turning on and just keeps restarting is because the TV itself or maybe Samsung the company is experiencing a bug.
There are sadly going to be various problems for many Samsung users for a variety of reasons since Samsung is so heavily utilized and demanded.
The reality is that bugs are sadly unavoidable. Various industries and pieces of technology alike fall prey to the vicious bugs that circulate the technology systems. Your frustration is heard and understood, but all you can do is sit tight until the bug works its way out or system developers are able to tackle the issue for you.
You can also reach out to Samsung and let them know that you are experiencing these problems. It may help them become notified of the problem faster and get to working on a solution for you faster than before.
Fix 4 – Reset TV
You can follow some simple steps to resetting your Samsung TV as well if you still have not been able to get your Samsung TV working and not constantly restarting.
Your first step is to power on your Samsung TV.
1. Press the menu button on your remote.
2. Select Support on your TV and then Enter.
3. Click on Self Diagnosis.
4. Select Reset.

This will hopefully solve your issues and get your Samsung TV to turn on without restarting.
Fix 5 – Contact Samsung
