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?

Yes two of the three were pluged into a power strip surge protector. I do not have a whole home sure protector on my box though

And nothing else is blown

I’d make sure there’s good ground and have surge protector or ups for it as well

In case some are not aware, not all power strips have surge protection. This is the is-it-plugged-in level of tech support.

Fyi, the protection component in surge protectors can eventually fail even to small surges. Good surge protectors won't provide power if the protection component is dead. They usually have an led indicator that protection is active.

If you're not sure your surge protector is actually good, I'd replace it. I'm a fan of the tripp lite ones.

Sounds like I should get new ones and when I am not using them I will unplug

Was going to be my first suggestion. If you are not there regularly, I would unplug anything I can. Hell, I'd even consider flipping breakers with as many issues as you are having.

A potential cause you could be experiencing is random surges from your power supply (Cleco). Had a place several years ago that this would happen to, I would be home then there would be a sudden buzzing noise, and my lights would get brighter, then it would be back to normal. Chased it for months because it was so sporadic that my electrician & Entergy could not replicate it to figure out the issue. After an electrical fire at a neighbor connected to the same transformer, Entergy replaced something in my breaker box and the problem stopped.

Do not leave an LG OLED unplugged. It is bad for the screen. YouTube it.

If you are near or on water and the TV's exposed to ambient air temps it may be condensation forming inside the circuits, the transformers always give a out a little heat even with the tv off and plugged in. if part of the tv cools down it will cause condensation to form due to the temperature variance. A little moisture can kill your circuits.

I think your two main likely problems are covered here. Either power fluctuations or condensation.

If the camp is air conditioned and you run the AC at all times (even when gone) then condensation is probably not an issue. But most people that I know don't do that as their camps unless they have a fairly high-end camp that is more like a second home.

Your solutions for condensation are to find a way to eliminate moisture at least around the TV. That means keeping the place air Conditioned or building some sort of box around the TV that can close and at least marginally seal it off and probably adding Desiccant bags inside the enclosure.

In order to block transients you could just try unplugging the TV. If you aren't going to be running the AC you could simply kill the main breaker, or you could invest in a power conditioner for the TV at least. Maybe something like this, I have not really looked into this type of thing in years though.

Or this

If you never kill power to the camp, you might also use a UPS if you can find a small one for cheaper. The only issue with a UPS is the batteries in them eventually need replacing (or the whole unit) and if power is out for extended times, that will happen quickly.
