Why my Samsung Galaxy Tab S 8.4 keeps on restarting?

Hello, I had a problem with my tablet "Samsung Tab S 8.4" that shows green flickers and keeps on restarting. I bought this tablet like about 3 years ago and the problem happened like about 1 year ago. The problem frustrates me very much. I tried almost every suggestions in the internet, I "factory reset," I "clear caches" all of my apps and I even upgrade my tablet into "Marshmallow 6.0.1 (Android version)." My previous android version of my tablet is like about 5.0 plus and when I upgrade it myself into "Marshmallow 6.0.1," the problem is getting worse. But the only thing that prevents my tablet from restarting is by charging it. Ughh, should I always charge my tablet whenever I am using it?

I searched in the web "why does my samsung tab s keeps on restarting" and I found a video in youtube, the link is "https://youtu.be/wdxf6HSRBzo." Once I've watched this, it is EXACTLY the same what happens to my tablet everytime. I viewed the comments and the subsciber said that the technician changed the motherboard to prevent this problem??? That disappoints me very much because it costs money.

And my question is, "Is there any suggestions that would fix my problem WITHOUT COSTING MONEY?"

I AM VERY CONFUSED WHAT CAUSES THIS PROBLEM... Is it the motherboard, or the battery, or the apps or what? I am very confused.

Answer this question I have this problem too

Is this a good question?

The charging port connection is not properly connected. Look on YouTube for video on disassembly and push down the charge

connector and clean battery connection and charge port with electronic cleaner and test it before putting the back case back on to make sure it works. That is what fixed mine. Others replace battery, and I don't think that's the problem. It's just a bad connection.

@Daniel Can you please, be more precise and send the link(s) to the youtube video.

The solder joints of the battery connector on the motherboard is weak. If you see it under a microscope, you will see some cold cracked solder joints. You need to re-solder them and you should be fine after that. I did some galaxy tab with the same problem.
