i am so confuse. plug already off. already on voltage controller. why still broken after hit by thunder

you mean lighting surge.

thunder is the sound

there is only 1 type of ligting surge right?

Sonic boom

Must be one hell of a lightning strike for the thunder to break tv

Thunder dun hit, lightning causes the surge in the electrical equipment. Yr house/condo does not use an effective lightning rod with proper earthing.

direct to wall or use extension? pakai la extension yg really surge protector.. or ups ke

If direct strike the arc will just jump. A mere mm gap in switch does look like any other conductor to a 3000 kV arc

If the strike is very near, your house and internal wiring itself will generate surge via induction.

time to consult theoutspokenguy for 75" tv

through the aerial?

Well the damage already done, by a new tv, at least u are fine, that how life it is.

do earthing test on your earthing pit

Tanda dari tuhan

If you unplugged confirm no kena

Lain kali masa ribut petir, cabut plug terus. Kalau nasib baik, hanya fius dekat plug tu jer yg rosak. Ganti fius baru few ringgit. Kalau nasib tak baik, electric circuit hangus, TV boleh buang

TV and router kena fried few times despite having copper rod, when pasang got test resistance value all within range. Didn't install lighting arrestor, installed sod at dB instead + lightning isolator at TV and router. Hopefully won't kena again 😂

salahan Thor, send LOD to Thor please

you mean lightning surge?

lighting itu cahaya

many house use poles for electricity, those can be medium for electricity surge.

he got 2.
can donut 1 to TS

congrats.. time for a new TV

No lar, salahan DAP as always.

how many decibel is the thunder able to break your tv

break as in the tv pecah berkecai?
but ayam hook tv with surge protector extension with surge cube so far touchwood ok lah. last time use one APC one burnt should be it is doing its job.

off no use cause can arc.... got connected to antenna or not?

need to unplug from mains

install SPD, call mahbayu

buy belkin surge protector.

How did your TV get hit by thunder? The sound waves and vibration so strong?

the best is unplug from wall socket and unplug Antenna or satellite cables and unplug network cables, confirm safe.

At least you do not have to think twice whether to buy new TV or not.

you need to pull out plugs before lightning storm .

your house has poor earth grounding .

or possible your Tv antenna got hit .

ada insurance?

plug x cabut ke bang?

House grounding is not meant for lightning, unless you install lightning rod on rooftop.

Landed house? Old apartment or flat?

Usually new condo is stable one

Even if u off plug or switch; there is electric leakage. This is normal. But normally it is very low leakage.
For yr case, it is very high leakage. Most probably, yr house light also cannot tahan lama even if u use LED light. Yr TV & light still take & consume electric when u switch off bcoz of this leak.
Then yr grounding also not very good. That's why yr TV broken after hit by thunder.

For yr case; u have 2 option... 1st- Make new wiring & replace main switch..
2nd- Take out yr TV plug everytime when not use..

need to redo grounding, pls consult mat goreng

ok
i mean the house tnb power earth to rod.
need to check if within the specs / recommendation.

Option 3, shift house to newer condo

dah lama never hear before electrical equipment hangus cos of lightning surge

TV sekarang ada orang pakai antenna lagi kah ?
Bukan semua smart tv tengok melalui unifi saja ?

plug already off.

lightning hit near your house?
i nearly died from this.

How come there power leakage when plug is off. No such thing. The only way people talk about leakage is on appliance that is never off like when you off using remote or anything on standby. TV is one of them.

Your house grounding is to protect you from electrocution when touching faulty appliances with Live wire or AC short-circuited to appliances body. Protecting house from lightning means you need to install lightning rod on top of your house rooftop and have sizeable copper strip to grounding rod in the ground. House grounding wire is not capable to carry high current caused by lightning.

many houses esp in small town , kampong , rural still use antenna.
plus many houses never dismantle the antenna , and lightning can hit these and the surge flow into your house.

i see u like to play with words. or weak on your knowledge.

1.when plug point is OFF . the surge can jump the gap . You can call this leakage thru the air.
2. the neutral is still connected . the surge can flow in/out .

Melancap to adeline je la gosok bebird prime

Tengok apa tv

do you have astro?
because it might struck the plate. one of the main culprit

I don't deny what you were saying but my understanding was that he was talking about leakage when power is off unrelated to lightning. If you read about leakage, it is described as what I explained.

The electrical jump spark between two point I believe is not called as leakage but electrical discharge.

off but unplugged or not bro

What type of voltage controller are we talking about here? Did the controller also get damaged?

Sounds like surge current. Install surge protection device (SPD) but before that you need to make sure your earthing resistance reading is within spec by ST. Else SPD won't work fully

Electricity can leap through empty air, switch is off position does not guarantee electricity is not strong enough to leap through and pass to other sensitive electronic equipment. Empty air just have very high resistance value only. The more resistance you create between the electricity source and the equipment, the harder it is to reach the equipment, such as pull the plug. But a direct strike onto your house and through the window still probably can fry equipment even if unplugged.

Nothing is guaranteed in the natural world. The only ultimate mitigation method is to save spare money to buy a new one in case of kena murphy's laws.

You mean lightning surge

Lighting is the illumination

Correct me if I am wrong here.
If the plug if "off" but not unplug from socket, lightning high voltage surge can still pass through the socket. There is no gap to jump. Therefore, if you unplug from mains socket, any surge will not pass through to yr tv.

Lightning can travel through kilometers of air. Why u think your switch few mm air gap can stop lightning?

Thats why best way is to have a damn proper grounding installed by a certified electrical contractor registered with suruhanjaya Tenaga. Not those ah seng ah Li muthu bangla contrator.

A house with good earthing will not trip regardless how strong the lightning. While a bad one will keep trip with every lightning. The MCB only trips when there's a huge surge, meaning the lightning induced current entered your housing wires.

I guess your tv has been… thunderstruck.

in theory it should work but in reality all bait only
my dad kena so many times
my house macam lighting magnet, everytime it rains then will trip something
alot of eletronics fried coz of it
buy wtv surge protector lan jiao shit also kena
so much so claim from the surge protector company and all they did was give another of their surge protector like sohai ur product failed to protect my eq, i want u to reimburse my eq not give another of ur lanjiao product
moral of the story is, lightning arrester is the only legit shit
surge protector all talk cock only lol

i think kena overvoltage

can claim from condo management

modern tv's like Samsengs are purposefully designed to break upon slight power surges, there's no fuse designed on the power board.

its all buy and throw away business model

are you using those SPD in the fusebox like Hager/ABB/Schneider?

TV can cater max 240V ............ any higher will destroy and burn the component.....

Now your TV component partial will be blacken already if you open it and see...

So old thread cannot be reply? Must open new thread

when OFF , the socket metal contacts separate to break the current flow .
A high voltage surge will spark across this metal contacts ...enough to zap the electronics .

yes unplug if you want 100 % safety.

huh?.. who uses aerial nowadays?.. all wifi/ lan format

i suggest you get a certified electrical tech to check the house
power wiring and also the earth rod resistance .
All must be within the recommended specs.

houses that often trip power via RCD need to do the above check .
the power trip already tell you something is wrong.

surge protector help protect from surges and/but the effectiveness depends on the earth rod resistance .

It's normal la for leakage & power loss for any house. It's no joke.
But the voltage is very low. U only put it to minimum which is tolerable.
However if switch is broken, low quality, wiring no good; then leakage very high.. Light or TV also can cepat rosak when not turn on..
U can see in minute 10:00 in video; there still electric leak (switch turn off)- no light turn on as voltage very low to turn on the light. This is normal.
That's why if long holiday or balik kampung, better pull out Tv plug..

if you leave the plug connected but switched off, the ground and neutral wires are still connected directly to your tv, only the live wire is disconnected. so there's still a path for the surge to hit your tv. best is to unplug terus

Brother my childhood BM teacher would pull her hair if we mistakenly interchange kilat and petir kek

I'm not sure what qualification this person has but his description is misleading. I would say it is not correct. The "leak" in this demo seems to me is not about switch leak. Even if you remove the switch and separate the two wires in the switch by few inches apart, you would still get the voltage reading. It has nothing to do with switch.

The phenomenon that we are seeing here is ghost or phantom voltage. Many people do not really understand the difference between voltage and current. It depends on the wiring in the wall. In my house also certain points even get 20V when measured with multimeter. This is the voltage reading but there is almost no power this voltage can supply. It probably can lit the neon indicator on the switch. That is why those switch with neon bulb still lightly lit up when switch is powered off.

The voltage on the wire is induced voltage by the live wire adjacent to disconnected wire laid next to it. In house wiring, you are most likely pull the L and N wire next to each other or they are laid together in conduit including the switch wire. Even when the switch is off, the AC on the L wire will induce the switch wire next to it and generate voltage. Same concept like transformer. The primary winding and secondary winding do not physically connect to each other but the voltage is produce at the secondary winding still. However, unlike the wire in the wall, there are many loops of winding wire that collect much of magnetic flux to generate power or current to power load at the secondary.

I bet if the guy use a LoZ (low impedance) multimeter, the voltage reading would be zero.

1. Through antenna, normally the highest point at your house.

My Samsung tv 1 of the hdmi port broken which connected to Astro decoder during lightening , the Astro decoder itself gone case .
The surge might pass from other type of connection , not the power cable itself .

Old voltage regulator may not be able to sufficiently protect your devices.

Also your TV could also be already on the edge, that power off and on could just be coincidentally broke it.

dei unplug tv saja not enuff, did u unplug whatever the hdmi is connecting to? did u unplug whatever cables thats connecting to ur tv? no right. Lightning travels to whatever thats connected via power plug. Mostly lightly strikes via power plug then hdmi.

worked a few years in an electrical shop...most cases of burnt tv from lighting is antenna - at the area i worked. off power not enough must unplug. most househole surge protector are those cheap type...likely not certifed etc....and those suually get burnt also.

after we install antenna, we always tell owner to unplug everything when raining or lighting...but it happens alot....the antenna mixer and booster also burnt a lot.
