I have a Samsung UN55B8000XF version SQ01. I plug it in and a relay just clicks on/off. If I unplug A/V board it stops and stays on. P/S or A/V board?

Change the video board. It seems like it is blocking power. The relay signifies that power is working properly.

Samsung TV shutting off by itself and relays clicking

If you don't know what you're doing, don't open it up to fix it!
There are HAZARDOUS voltages on the power supply board EVEN WITH THE TV UNPLUGGED!!! The capacitors can hold a charge for several weeks!

Clicking noise can be coming from bad capacitors on the power supply board.

It's usually easier to just replace the power supply board.

My Samsung won't turn on. 32" Samsung TV flashes red when it's plugged in. I replaced one fuse, still has the issue.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Samsung 52" turns on and off clicking and doing the power on tone then clicks again and does it over and over once I unplug the t con board it stops and the screen lights up. But stays black of course

Notice that when you unplug the t con board the set does not shut off - you have inadvertently identified the bad, shorted board that needs replacement. That board digitizes the info and puts it on the screen.

When you turn on the TV it takes about 20 to fully turn on. sometimes we get pink lines on the screen.
