If these wires are of low quality or damaged in any way, they will not be capable to supply the needed power to your Samsung TV which is required. Normally, they are seeming to be good but after having a deep look you would be able to see the tiny wires coming out of it or may be it would be broken from somewhere. If you are using a low quality power cord everything seems to be good but you have to change them otherwise, you may cause serious damage to your Samsung TV.

Another possibility could be that the power cord is totally fine and of good quality but still your Samsung TV keeps turning off after every 5 seconds. Well it don’t have to be damaged to cause the problem. You will encounter power problems if the cord is not properly seated in the outlet or the extension cord you are using is faulty

To make sure if the power cord is fine, try to plug in your Samsung TV directly into the wall if you have been using an extension cord. If your TV seems to start working normally then order a new set of electrical power cable compatible with Samsung TV. I would recommend you to try Ancable C7 power cable as it is almost 12 feet lengthy and also affordable.

3- Overheating

The other possible reason behind your Samsung TV keeps turning off after every 5 seconds could be that it is over heated. Your TV get over heated when you do not turn it off for several hours may be because you have being watching a hole Netflix serious in a row and your Samsung TV was on from last several hours or your room temperature is too high that your Samsung TV keeps getting overheated. You can simply verify that by touching its front or back if possible.

If you observe that your Samsung TV is overheated, then it is time to cool it down by turning it off for around 5-10 minutes. Some people has recommended for 30 seconds but it is best if you can turn it off 5-10 minutes because this time can be good in any case to get it cooled down under any circumstances.
