Sony Bravia - Does the TV need to be connected to a surge protector

I warmly welcome,
friends have a Sony Bravia TV installed. I wanted to ask if it is necessary to have a surge protector, I know it should be, but my friends don't want to hear about it? The TV has a power supply as in the picture (sorry for the sharpness) does it have any protection? I would like to add that their decoder has recently broken down during a gale, now they have the card inserted directly into the TV.
Best regards,
Matthew

Hello.

Generally every power supply includes (or at least should include) some protection in the form of an ordinary flux, but a surge protector will not hurt them. Honestly speaking, personally, I had some unpleasant situations and now only uses them.

Thank you for your answer. In total, there is still a problem that there is no earthed socket and from what I know, the surge protector fulfills its assumption only if it is connected to the ground. Uncle said that he would not call an electrician to check the socket if the manual says "the power supply is to be connected to a power outlet" and there is not a word about a surge protector. I know that you can bridge the PEN neutral wire with a pin, but after yesterday's discussion on this topic, I ran out of arguments, although I found the terms of the SONY warranty somewhere and it probably says that the warranty does not cover failures caused by voltage surges. As he said, he does not want to pay for something that may not be needed at all. His next argument was that the plug from the TV power supply is flat and since it is without grounding, the strip is unnecessary, although from what he knows, the equipment connected to the strip does not have to be grounded, it is important that the strip is connected to a grounded outlet. I will add that I tried to convince him with my own example, I have a Samsung TV myself and it is connected to the strip, but my argument was beaten by Sony's superiority over Samsung. Would anyone have any argument in favor of having a strip or would it be better to give up? Thank you in advance for your answer.

Ground has absolutely nothing to do with anti-overvoltage action, because it does the protection for it varistor. Earthing is just another protection, which of course is not mandatory by law, but it's better to have than not to have. But that doesn't change the fact that the lack of grounding does not eliminate the possibility of having such a strip.

And what should it be connected to if not to a socket ...? Uncle has any other idea? Well, the surge protector is hardly said to be true, some devices require it from the top and write in the instructions, but it is not recommended as much as it simply "gives comfort to the spirit and body". In other words - you sleep more peacefully with this strip . ;)

What you mentioned is the so-called reset the pin , which is how you rightly noticed connecting N to PE. Honestly, the electrician is not really my hobby, because I search mainly in electronics, but as an electronics technician in general I'm not a fan of pin reset ...

Go back to the beginning.

If he is not convinced by such arguments, I will give you this advice from pure experience - do not try to persuade everything has further consequences.

Thanks for the advice and clarification

Will the surge protector be or not, in the event of a storm and lightning strike, it will not save the TV anyway - why, because the TV is connected with a wire to the socket, and the electrostatic charge will still be able to penetrate the TV motherboard.
In addition, the TV has an external antenna, so the effect is known ...

Really nothing is 100% protection after removing the plug from the socket ... But it's generally better to have these anti-bursts anyway. (especially that it does not belong to the "luxury" commodity), because then at least it is some the chance that the equipment will not suffer [so] .

If, during a storm, the skirting board does not fulfill the task, why should it be bought and used. No need to throw money on some slats.

Well, about the same speech - if such a strip was for nothing, it would not be. The varistor is supposed to take "on the chest" everything that may cause, for example, a lightning strike or the occurrence of any other anomalies in the network. And even if he would not save the equipment 100% (because something can always get damaged, even behind the varistor, there is no power for it anymore), there is certainly a smaller chance that the entire RTV will go to hell right away.

With an external power supply, it makes no sense to give a strip. Recently, the TV power cord was like a "computer" with grounding. Now the usual two-wire.
When it comes to lightning, it is only through the antenna. Maybe once in every thousand or so someone has an overhead line and lightning strikes through the net.
The only explanation to give the strip a peace of mind is that you have done everything they recommended and if you "hit" it, there is no help.

What will you get if you remove the plug from the power socket, if you leave the external antenna connected to the TV - and just like lightning strikes you have the TV to throw away.
The same applies to network equipment - everything is turned off, but the cable with the signal from the outside coming from the wall is left in the LAN port and the next LAN cable goes on ... - which gave such a current disconnection, since electrostatic discharge will go through the LAN cable. "all over the web.

Thanks for quoting my wisdom.

Maybe more as a warning how sellers are luring customers into a bottle.

A UPS would be more helpful in terms of such protection than a power strip.

Bravo. Exactly just like that. I was just watching a seller make older buyers happy (marriage). They also purchased a TV set, but it turned out that a power strip was needed for good reception. There were two types on offer (generally cheaper and significantly more expensive) and guess which one he recommended effectively?

Fact, gentlemen, through the antenna, there is not much chance for rescue ... Lest it come out with what I insist.

YOU, no, but the author YES.

Ie. you know, I also agree that when it cracks in the antenna there is not much you can do (admits - in previous news I forgot to mention To the author that there is still a possibility of a lightning strike in the antenna ...), but I still do not say that such a strip would be unnecessary, because it gives you some protection against any anomalies in the network itself (but only in the network - we turn off other "external" factors) .

If you agreed from the beginning, you would not write about saving PLN 50 for PLN 4,000 spent. You withdraw because you were left alone with your faith in the slats.

... after all, I clearly marked in this thread that I forgot to mention it, so later I was not entirely convinced ... But apart from the lightning / antenna issue - it's better to have such a strip anyway because it still protects at least to some extent compared to "ordinary". But it is what who wants and likes.

If I insisted, I could say, for example, "nothing will fall on the antenna and only take the anti-wire protector because it is a miracle and magic and all the best!" ...
