Why is my TV constantly restarting?

Here's the issue. I'd plug in my LG tv, and after 10 seconds. It would just restart! and do the same thing over and over and over again! I've factory reset it and that hasn't fixed the problem, I'm in need of assistance!

Update: I have removed the backplate as suggested. Currently, I'm stuck because I'm new to all this technical stuff, and fixing the faulty power supply of the Television

@johndius this can be cause by faulty power FET's on the power board. Unplug your TV, remove the back and check the components on all boards. Focus on the power board. It might help to take some good pictures of your boards as well as the layout and post those with your question. Use this guide for that. It will help us to see what you see. Of course you will at least having to use a multimeter for that.

I've sent a picture to the question of the removed backplate, what should I do next?

close ups of the boards will help. I am in particular interested in the one on the left, the power board.

I've just uploaded the various pictures of the power board to the question (above)

Check the voltafges on your connector at the top right. You see the output values see what you get on those. BTW what is the chassis number of your TV. I do have various schematics for 42LN5700 but they all differ from your power supply.

@oldturkey03 I have not checked the voltages yet, but my TV model number is 42LN5700 (42LN5700-UH) which you have stated
