A 43-inch TV uses different amounts of electricity depending on the model and settings. On average, a modern 43-inch LED TV might use between 30 and 70 watts while you are watching it. This power usage affects your energy cost over time. Knowing how much electricity does a TV use helps you see where your money goes. We can figure out the potential cost by looking at how many watts the TV uses. We also need to know how long it is on. The price of electricity in your area is important too.

What Power Does Your TV Need?
Every TV uses power. This power is measured in watts. Watts tell us how much energy is being used right now. A higher watt number means more power is used. Your TV power consumption changes. It is not always the same.
What Makes a 43-Inch TV Use More Power?
Many things affect how much electricity a 43-inch TV uses.
Let’s look at some of these things.
Different Screen Types
TV screens use different kinds of light.
Older TVs used a lot more power.
Most new 43-inch TVs use LED technology.
Power usage 43 inch LED TV is usually quite low.
Some TVs use QLED or OLED.
QLED is like LED but better picture. It uses similar power.
OLED screens light up each tiny dot. They can use more power than LED. But it depends on what is on the screen. A dark picture uses less power on OLED. A bright picture uses more.
Brightness Settings
The screen brightness matters a lot.
A bright screen uses more power.
Turning down the brightness saves energy.
This is a simple way to lower your TV power consumption.
Most TVs have a setting for this.
You can find it in the picture menu.
Picture Mode
TVs have different picture modes.
Modes like “Vivid” or “Dynamic” make the picture pop.
They often turn up the brightness.
They can use more power.
Modes like “Standard” or “Cinema” might use less power.
Using a power-saving mode is best.
Many 43 inch smart TV energy efficiency settings are built-in.
What You Are Watching
The picture on the screen changes.
A bright scene uses more power than a dark scene.
Watching an action movie with lots of bright explosions might use more power.
Watching a dark movie might use less power.
This effect is bigger on OLED TVs.
Age of the TV
Older TVs are usually not as good with energy.
They were made before energy saving was a big deal.
A new 43-inch TV is likely more energy efficient.
It will use less power than a 43-inch TV from ten years ago.
Smart TV Features
Smart TVs connect to the internet.
They have apps like Netflix or YouTube.
These features use some power.
Even when the TV is “off,” some parts might be working.
They might be waiting for a voice command.
Or they might update apps in the background.
This adds to the overall TV power consumption.
But the main power use is when the screen is on.
Typical 43-Inch TV Watts Usage
How many watts does a 43-inch TV actually use?
It changes from one model to another.
But we can give you a range.
Most 43-inch LED TVs use between 30 and 70 watts while on.
Some might use a little less.
Some might use a little more.
This 43 inch TV watts usage number is what you need to know.
Look for the energy label on the TV.
It is often on a sticker.
It tells you the power use in watts.
Check the TV manual too.
The maker’s website will also have this info.
Here is a rough idea:
| TV Type | Typical Watt Range (While On) |
|---|---|
| 43-inch LED | 30 to 70 watts |
| 43-inch QLED | 40 to 80 watts |
| 43-inch OLED | 50 to 100+ watts (can vary) |
Remember, these are just examples.
Your exact model might be different.
Power usage 43 inch LED TV models are generally on the lower end of power use.
Grasping Standby Power
What happens when you turn off your TV with the remote?
It does not usually turn off completely.
It goes into standby mode.
Standby power 43 inch TV is the small amount of power it uses when it looks off.
Why does it use power in standby?
It needs to be ready.
It needs to turn on quickly when you press the remote button.
It might stay connected to the internet.
It might be waiting for updates.
Standby power use is very low.
It is usually less than 1 watt.
Sometimes it is 0.5 watts.
Or even less.
But it uses this power all the time it is in standby.
This adds up over the year.
It is a small part of your TV energy consumption cost.
But it is wasted energy.
If you want zero standby power:
You need to unplug the TV from the wall.
Or plug it into a power strip with a switch.
Then turn off the switch.
Measuring Your TV’s Power Use
You can find out exactly how much power your TV uses.
Check the label on the back of the TV.
It might say “Power Consumption” or just list a watt number.
Look at the energy guide sticker.
It gives you an estimated yearly cost.
It also shows estimated yearly kilowatt-hours (kWh).
For a real-time check:
You can buy a power meter.
These meters plug into the wall.
You plug your TV into the meter.
The meter tells you how many watts the TV is using right now.
You can see the watts change with brightness or different shows.
This is a good way to check standby power 43 inch TV too.
A meter gives you the most accurate power usage 43 inch LED TV info for your home.
Deciphering Your TV Energy Consumption Cost
Now let’s talk about cost.
Electricity is sold in units.
These units are called kilowatt-hours (kWh).
A kilowatt-hour is 1000 watts used for one hour.
Think of it like miles per hour.
Watts are like speed (how fast power is used).
Kilowatt-hours are like distance (total power used over time).
Your electric bill shows how many kWh you used.
It also shows the cost per kWh.
This cost is different depending on where you live.
It changes over time too.
You can find your cost per kWh on your electric bill.
It might be listed as cents per kWh.
For example, 15 cents per kWh is $0.15 per kWh.
To calculate electricity cost TV:
You need the TV’s power use in watts.
You need how many hours you watch it.
You need the cost per kWh.
Here is the formula:
(Watts used by TV * Hours used per day) / 1000 * Cost per kWh = Cost per day
Let’s use an example.
Say your 43-inch TV uses 50 watts.
You watch it for 4 hours a day.
Your electricity cost is 15 cents per kWh ($0.15/kWh).
Calculation:
(50 watts * 4 hours) / 1000 * $0.15
(200 watt-hours) / 1000 * $0.15
0.2 kWh * $0.15
= $0.03 per day
So, this TV might cost about 3 cents a day to watch.
This calculation helps figure out the TV energy consumption cost.
To find the cost per month:
$0.03 per day * 30 days = $0.90 per month
To find the cost per year:
$0.03 per day * 365 days = $10.95 per year
This shows the average 43 inch TV electricity usage in terms of cost.
This cost seems small. But it adds up with all your other devices.
Let’s try another example with higher use.
Say your TV uses 70 watts.
You watch it for 6 hours a day.
Cost per kWh is still $0.15.
Calculation:
(70 watts * 6 hours) / 1000 * $0.15
(420 watt-hours) / 1000 * $0.15
0.42 kWh * $0.15
= $0.063 per day
Cost per month: $0.063 * 30 = $1.89
Cost per year: $0.063 * 365 = $22.995 (about $23)
This shows that cost changes based on power use and viewing time.
How much electricity does a TV use per hour?
In the first example, the TV uses 50 watts.
50 watts is 0.05 kWh (50/1000).
So, it uses 0.05 kWh per hour.
At $0.15/kWh, that is $0.15 * 0.05 = $0.0075 per hour. Less than a penny per hour.
In the second example, the TV uses 70 watts.
70 watts is 0.07 kWh.
At $0.15/kWh, that is $0.15 * 0.07 = $0.0105 per hour. About one cent per hour.
This hourly cost seems tiny.
But hours turn into days.
Days turn into years.
That is how the TV energy consumption cost adds up.
Knowing the TV kilowatt hour consumption is key.
More About Factors and Your Bill
We talked about factors affecting power use.
Let’s see how they impact the bill.
Viewing Habits
How many hours a day is the biggest factor?
Someone who watches TV for 2 hours will pay less than someone who watches for 8 hours.
More hours means more TV kilowatt hour consumption.
This directly raises the TV energy consumption cost.
Knowing how much electricity does a TV use per hour is useful here.
Multiply that hourly cost by your total daily or weekly hours.
Electricity Rates
The cost per kWh is also very important.
Electricity prices vary a lot.
They are different in different states.
They can be different in the city compared to the country.
The price might change during the day (time-of-use rates).
A higher rate means your TV costs more to run per hour.
If your rate is $0.25/kWh:
The 50-watt TV used 0.05 kWh per hour.
Cost per hour is $0.25 * 0.05 = $0.0125.
This is more than the $0.0075 at $0.15/kWh.
The cost per year would be higher too.
TV Settings Revisited
Brightness and picture mode save watts.
Saving watts means lower TV power consumption.
Lower watts means lower kWh.
Lower kWh means lower cost.
Even a saving of 10-20 watts can add up.
If your TV uses 50 watts instead of 70 watts:
That is 20 watts saved.
If you watch 4 hours a day:
That is 20 watts * 4 hours = 80 watt-hours saved per day.
80 watt-hours is 0.08 kWh.
At $0.15/kWh, that is $0.012 saved per day.
Over a year, that is $0.012 * 365 = $4.38 saved.
It might not seem huge, but it is free money saved.
And it is better for the environment.
Interpreting 43 Inch Smart TV Energy Efficiency
Modern 43-inch TVs are often smart TVs.
43 inch smart TV energy efficiency is generally good.
They follow energy standards set by governments.
Like Energy Star in the US.
Energy Star products use less power.
Smart TVs have extra features that use power.
Connecting to Wi-Fi uses a small amount.
Running apps uses power, but the screen is the main user.
Voice control features might keep a microphone “listening” in standby.
This uses a tiny bit of power.
Compare the energy use label.
A 43-inch smart TV might use similar watts to a non-smart 43-inch TV of the same age and type.
The “smart” part adds very little to the running cost compared to the screen itself.
The main difference might be standby power 43 inch TV models.
A smart TV in standby might use slightly more than a basic TV in standby.
This is because it stays connected or ready for commands.
But standby power is very low anyway.
Some smart TVs have good power-saving options.
They might have an ambient light sensor.
This sensor changes brightness based on the room light.
This can save energy without you doing anything.
They might have a setting to turn off the screen when playing audio only.
Or turn off after no activity.
These features improve 43 inch smart TV energy efficiency.
Different Screen Types and Power Again
Let’s compare screen types focusing on power usage 43 inch LED TV versus others.
- LED (or LCD with LED backlight): These are very common at 43 inches. They are known for good energy efficiency. Power usage 43 inch LED TV is usually the lowest among modern types for typical viewing. They use LEDs behind the screen to light it up.
- QLED: This is a type of LED screen made better by Samsung. They use Quantum Dots for brighter colors. They are still LED-based. Power use is similar to standard LED or slightly higher for peak brightness.
- OLED: These TVs offer amazing picture quality. Each pixel makes its own light. A 43-inch OLED is less common than larger sizes, but they exist. OLED power consumption depends greatly on the screen image. A dark scene uses very little power. A bright, all-white scene uses a lot of power. On average, a 43-inch OLED could use slightly more power than an LED if you watch lots of bright content. But the numbers are still relatively close for typical use.
For most people buying a 43-inch TV today, it will be an LED or QLED. Both have good TV energy consumption. The difference in watts between them for a 43-inch size is often not huge. The biggest factor remains screen brightness and how long the TV is on.
Steps to Lower Your TV Power Use
Saving energy from your TV is easy.
Here are some simple steps.
- Turn Down Brightness: This is the best tip. Go to picture settings. Find “Brightness” or “Backlight.” Turn it down. Find a level that looks good but is not too bright.
- Use Power Saving Modes: Most TVs have a mode for saving energy. Select this mode. It will often lower brightness and change other settings.
- Set a Sleep Timer: If you fall asleep watching TV, use a sleep timer. The TV will turn off after a set time. This saves many hours of power use.
- Turn Off TV When Not Watching: It sounds simple, but people forget. Don’t leave the TV on in an empty room.
- Avoid Standby (Optional): Unplug the TV if you won’t use it for a long time. Or use a power strip with a switch. This stops standby power 43 inch TV use completely. This saves a very small amount of energy. It adds up slowly.
- Disable Quick Start: Some smart TVs have a “quick start” feature. This makes the TV turn on faster. It uses more standby power to be ready. Turning it off might make the TV take a few extra seconds to start. But it saves energy in standby.
- Check Energy Label: When buying a new TV, look at the energy label. Compare the estimated yearly energy use (kWh). A TV with lower estimated kWh will cost less to run.
These steps directly lower your TV power consumption.
They reduce your TV kilowatt hour consumption.
This leads to a lower TV energy consumption cost.
Comparing TV Use to Other Devices
How does a 43-inch TV compare to other things in your home?
A 43-inch LED TV using 50 watts is not a huge power user.
Think about other appliances:
- Refrigerator: Uses much more power over a day, but cycles on and off. Maybe 100-200 watts when running. Runs most of the time.
- Desktop Computer: Can use 100-300 watts or more while in use.
- Gaming Console: Can use 100-200 watts or more while gaming.
- Lamps: An old light bulb (incandescent) might use 60-100 watts. An LED light bulb uses only 7-15 watts for the same light.
- Microwave: Uses 1000-1500 watts, but only for a few minutes.
- Air Conditioner: Uses thousands of watts when running.
Your 43-inch TV uses power while you are watching it.
The power usage 43 inch LED TV is similar to a few LED light bulbs.
Or less than a desktop computer.
It is much less than big appliances like fridges or air conditioners.
However, TVs are often used for many hours a day.
This long usage time means the total kWh adds up.
That is why understanding TV kilowatt hour consumption over hours is key.
How much electricity does a TV use per hour multiplied by many hours makes the cost show up.
Summing Up Your TV Power Use and Cost
A 43-inch TV uses electricity.
The amount changes based on the TV type, settings, and what you watch.
Average 43 inch TV electricity usage while watching is usually 30-70 watts for LED models.
Standby power 43 inch TV use is very low, less than 1 watt.
The total TV energy consumption cost depends on:
1. How many watts the TV uses (TV power consumption).
2. How many hours you watch it (how much electricity does a TV use per hour * total hours).
3. The cost of electricity per kilowatt-hour (TV kilowatt hour consumption * cost per kWh).
You can calculate electricity cost TV by using the formula: (Watts * Hours) / 1000 * Cost per kWh.
A 43-inch TV might cost roughly $10 to $25 per year to run.
This is based on typical use and electricity prices.
Changing settings like brightness can lower the 43 inch TV watts usage.
This reduces the TV energy consumption cost.
43 inch smart TV energy efficiency is generally good.
They use similar power to non-smart TVs when on.
But their standby might be slightly higher.
By knowing about your TV’s power needs, you can make smart choices.
You can save a little money on your electric bill.
And help the planet by using less energy.
Check your TV’s label. Find its watts.
Estimate your viewing hours.
Look at your electric bill for the kWh cost.
Then you can figure out your own TV energy consumption cost.
It is easy once you know the steps.
