36" Keeps turning off and on,...
I had an RCA TV that started doing something very similar. It would just go black and the sound would stay on. I did some research and found that there was a component board inside the TV that was notorious for having connections that worked themselves loose.
First, I'll give you the quick fix that worked for me. If you give the TV a good whack on the front between the speakers, it would get the display to come up again. This worked for a long time for me.
The real fix is to crack the TV open and examine this circuit board to examine what component on the board has a loose component and re-solder that. Most folks would not feel comfortable doing this, but that's when you've got to think if fixing it is going to cost you more than the TV is worth. Good luck.

I have a year old RCA 49in 4K TV that lost all power. Do you have any suggestions on how to resolve the issue?
Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
