My issue sounds similar. So get this. I have a 5 year old LG 55ga7900. My family was watching TV and it kept boot cycling. Shows LG logo, goes into find which display to use, off and back on again, over and over and never stops. Never-ending boot cycle. Replaced the power cable first, no lick. Get this, if I hold down either the power button on the TV OR remote, it doesn't boot cycle! The TV will stay on and work properly with one depressed and won't do the boot cycle. I could technically tape the power button down and have no problems. I went inside the TV and disconnected the button panel, thinking it was the internals of the power button shorting out. Took batteries out of remote. Same thing. It will boot cycle with the internal power button disconnected and the batteries put of the remote. I took the power delivery board out, checked all capacitors with a multimeter (I do pc repair for a living). Couldn't find anything blown on the power board. How in the heck does a boot loop go away if I hold either power button down and then boot cycle the moment I let go of the power button? I still think it must be something with the power board.

Yes, Here is the solution. I consulted various forums and tried everything.
My TV 65 4K CURVED 3D, 65UG870T restarts for no reason, does endless LG logo loop. Following are the steps I tried.
1.Pulling out the power cord for 30 secs and plugging back in.
2.Factory reset
3. Disabling HDMI CEC/simplink.
4.disconnecting all the cables, fire cube,xbox,ps4 etc. (I used Fire cube gen1, xbox one s, ps4 pro and samsung q70r sound bar)
I was almost certain that its a hardware problem.
Finally one day, on my own, I changed the firecube output to 1080p 60hz only and voila it worked !!!!!!!!!
Good luck guys
