Massive failure of Nintendo classic mini when connected to an LG TV. What's the matter?

Question

Iron

Poltergeist in the following: 1. Grandchildren bought SuperNintendo classic mini. Connected to a 42LG2000 TV, about 10 years old. Everything worked fine.
2. The image disappeared the next day. The sound remained. The console was exchanged in the store for the same.
Connected: there is sound, there is no image.
3. The second console was exchanged in the store for a cheaper option: just Nintendo classic mini.
Connected: everything works properly, i.e. fine. After turning it off for a 2-hour break, we observe the same picture as in the first case: there is sound, there is no image.
Replacing HDMI cords, alternating HDMI ports (there are 2 on the TV) and other actions have been tried.
The question itself: Can the TV disable the console and how to deal with it? 3 in a row!! consoles are broken. Grandchildren will bite their grandfather. Save, good people!

Answer 1

Of course it can, why not? The TV is powered by electricity, it is plugged into an outlet (already 230 volts!). the prefix, by the way, also feeds on it.
Maybe you shouldn't unplug it?
And yet, grandchildren collect a static charge, which can easily not match in sign and magnitude, either with a prefix or with a TV. Especially considering that those two are grounded - it will be even easier for the discharge to burn anything.
Or maybe the TV is faulty, operable, but, for example, "breaks through the case." Or there the filtering (or protective) elements have lost their characteristics, which leads to a surge of current at the moment of switching on or during operation.
It is strange why you simply did not read the conclusion about the cause of the breakdown - you were obliged to give it.
Well, or continue to suffer with the replacement, the guarantee is for each set-top box, that is, you can change the set-top box every two weeks and the guarantee will be eternal! :D
