I will explain CRT tv power consumption in detail. Older CRT(Cathode Ray Tube) televisions are being replaced with lighter, higher definition flat screen equivalents as technology advances. These screens are also more environmentally friendly than CRTs because they consume less power. But not all flat-screen televisions are created equal. Plasma displays, CCFL LCD televisions, and more recent LED TVs are all options for consumers.

CRT tv power consumption

For their size, CRT televisions consume a disproportionately high amount of power. A CRT television uses roughly 0.3Watt per square inch, according to Agilent. Some CRTs, though, actually consume less energy than current high-definition flat-screen televisions. The HDTVs consume more electricity since they have bigger screens and more surface area. Measure the overall screen area before determining whether to go from a CRT to a flat-screen TV to estimate how much power you’ll need.

LED Power Use

A subclass of LCD TVs, LED TVs, utilizes even less power while providing a more dependable image. LEDs offer greater efficiency and several power-saving features. Compared to LCD televisions with fluorescent illumination, this sort of television offers a wide range of extra functions and is typically available in HDTV format.

High-end LED televisions, according to CNET, utilize closer to 0.075 Watt per square inch when calibrated to the specific user than the industry average of 0.1 Watt per square inch.

Cost Considerations of CRT TV

The cost savings from switching from a CRT to an LED television might not be significant. In the long run, it can even end up costing you money. Most LED televisions are expensive displays, with new prices ranging from $1,000 to $4,000.

According to CNET, switching to an LED television instead of a less expensive LCD only generates a $20 annual savings. According to Investopedia, the annual cost of using a 19-inch CRT television is roughly $25. While a similar-sized LED screen would save $17, most LED televisions are substantially larger and consume more electricity.

Environmental Considerations

It’s not always more ecologically beneficial to upgrade your television. Even though the LED TV you select uses less energy, its manufacturing and shipping often harm the environment. High-quality glass and semiconductors require a lot of energy to produce.

A used CRT can also be challenging to dispose of. If not properly disposed of, these machines’ relatively high levels of lead and phosphors can result in major pollution issues. Most recyclers either don’t accept CRTs or do so at a steep cost.


CRT tv power consumption is more in comparison to LED. Since LED displays give the biggest power savings and are becoming more affordable, we recommend using them. Select a display size that is comfortable for you, and make sure your display is correctly calibrated to save energy.

Lower the brightness, turn on energy-saving features and ensure the monitor enters sleep mode after five or ten minutes of inactivity. As less energy is required to light the screen, several research studies also suggest that changing your system themes to a darker hue may help you save money on electricity.

Remember that most displays still consume 0.1 to 3 watts of electricity even when they are off or in sleep mode. Unplugging the screen if you will be gone for a long time may also be helpful.

Frequently Asked Questions

How much energy does a vintage CRT TV consume?

The U.S. Environmental Protection Agency (EPA) estimates that a normal 28-inch cathode-ray (CRT) television consumes roughly 100 watts. Depending on the type and the programming, a 42-inch LCD set can use twice as much energy as a plasma display. 1

Are CRT TVs more consumed power?

The data also showed that the CRT used 8 W less electricity than the LCD while the same televisions were in standby mode (when they were off but still connected and using some power) for 19 hours each day. 4 W. And at 95 W and 65 W, respectively, a 25-inch CRT consumed more energy than a 35-inch LCD.

What makes CRT TVs superior?

CRTs are better at enlarging low-resolution images to fill a larger screen than current LCD televisions, which are fixed-pixel displays that use a grid of pixels to display an image.

How much power is consumed by a 32-inch CRT TV?

32″ LCD: 50 to 85 watts, typically 65 to 70 watts. For instance, older 32″ CRT TVs needed up to 150-200 watts, with an average consumption of about 120 watts (even more if the screen brightness is increased).
