What keeps happening to my tvs

I am now on my third tv that will not come on at my camp.. one was a viso and was outside on the porch for a while but didn’t get wet or anything and isn’t around saltwater ..I thought Mabe we had a lightning strike. I then got a LG and I literally hooked it up turned it on to make sure it worked and turned it off. Came back two months later…wouldnt come on. Dead as a doornail.
I thought Mabe I had a wiring problem out there that was frying my TVs but I can’t find anything wrong and my outside speakers and radio are pluged into the same outlet with no problems

Fast forward a few months to now I come in to my camp and try to turn on the tv and my 70 inch LG in the living room Won’t come on.

The red light flashes under the LG emblem but nothing works on remote or with power button on tv.

Do I have a wiring problem? This has happened two two different brands in two different locations in my camp and three different times..

Are my TVs worth trying to fix?
