LED lighting is one of the most impressive lighting technologies to date. Rapid developments made it into a valuable energy-efficient light. You can also find LED technology in your shoes, watches, and even your TVs.

An LED screen can provide better contrasts and a brighter display for less power. Many LED TVs have less heat dissipation and come with a thinner panel. With good care, your LED screen can last for four to ten years.

Having trouble with your LED display screen? In this article, we give you signs that your LED screen needs repairing or replacement. If your LED screen starts showing any of these signs, it may be time to replace your screen.

  1. Dead Pixels

A dead pixel happens when a pixel or a group of subpixels stop lighting up. This may appear on your LED screen as a black or green dot. Before you start looking for an LED screen supplier, confirm that it’s a dead pixel.

Some dead pixels are actually stuck pixels. Stuck pixels may occur when your transistor has issues. It may be out of place and could have different colors. If you think you may be dealing with a dead pixel, take it out for repairs.

Make sure you have a clean LED TV screen. A small piece of dust, dirt, or debris may look like a dead pixel. Instructions to clean your TV may differ depending on the brand you use.

If you have LG and Toshiba TVs, clean the screen with a dry cloth. For a Panasonic TV, use a soft lint-free cloth. Samsung offers a separate cleaning cloth with their TVs.

  1. Distorted Colors

Your TV screen may be suffering from malfunctions if its colors appear distorted. You may not notice the discoloration at first because this issue happens over time. When this issue starts, only one color tends to weaken or fade.

Your TV screen may also suffer from phantom colors. These appear on areas on your screen that should be completely white. Phantom colors may appear as smeared bright colors across these areas.

Before contacting a professional, check if your TV is in a self-test mode. Press your remote’s arrow up then arrow down buttons while standing near your TV’s power cord. Within 5 seconds, unplug your TV then wait 15 seconds more before plugging it back in.

If this doesn’t work, try again but press the left then right arrow buttons instead. With the original remote control, you may also try going to your TV’s settings. Turn off Self Test Mode from there.

Check if your TV has loose video input wires. These your TV’s red, green, and blue component cables. Make sure your video input ports are clean and functional.

If you have a speaker system, consider moving it away from your TV. The magnets can interfere with your TV screen. If none of these methods work, contact a professional.

  1. Image Retention

Don’t confuse image retention with a screen burn-in. A screen burn-in is a more serious LED screen issue that refers to permanent damage to your screen. This degradation leaves a permanent static image on your device’s screen.

Image retention is a less serious issue than you can fix at home. This may occur when you change channels or input different media. Image retention is when an image sticks to your screen for a few moments.

Try adjusting your TV’s brightness and contrast levels. Play different media and check if a still image stays on your screen. Try enabling your TV’s Pixel Shift feature.

This feature will allow images on your screen to adjust and vary pixels. You can find the Pixel Shift feature on modern TV sets. Enabling this may help fix the phantom image.

  1. Fading Screen

A faded picture may appear as a stain-like mark in some areas of your screen. A faded screen may occur if your TV has a faulty backlight system. If this happens, you may need to get TV repairs or a replacement.

Faded spots are common and may be a sign of other serious issues. Your TV may fade to black within seconds or minutes after turning it on. Try running your TV through a picture test before contacting a professional.

Some models allow you to run a Picture Test on your TV. This test gives you an on-screen questionnaire. Your answers will help you determine if the issue lies in the source or your TV’s hardware.

  1. Fuzzy Screen, Bars, or Lines

A fuzzy screen drowns out any small details and loses the quality of your picture display. This may occur if an issue lies between your TV’s display and resolution. This gives you a 480p digitized standard.

Try swapping out your cables if you still have a fuzzy screen. HDMI cables can give better images than a component video cable. Try borrowing a cable from a friend to see if you need a replacement.

Your TV may also start displaying fuzzy images with bad weather conditions. If you have an older TV, it may be time to get a replacement. You can resolve this issue immediately if you have a modern TV.

If your TV starts displaying bars and lines, you may have issues with your connector. Magnets near your TV can affect images and picture quality. Even if you demagnetized your TV, magnets in your speakers or other devices could mess up your images.

You can remedy this issue by fixing cables on your TV. Fixing loose cables is an easy fix. Since you have to open your TV, you may need to contact a professional.

5 Signs You Need to Replace Your LED Screen

Here are some common signs that your LED screen needs a replacement. You can remedy some of these issues yourself by troubleshooting your TV. If the problem persists, look into getting repairs or a replacement LED screen.

Does your LED screen have other problems that are not on the list? It may mean that the display isn’t the part with an issue. Check out more of our informative blogs and guides to learn all you can today!

LED lighting is perhaps the best and most versatile lighting solution there is. With LED lighting, you can save more money than any other lighting system, and benefit from direct and focused lighting. Lighting is one of the main features in any room. When you walk in to any room, it’s the lighting that allows you to take in the rest of the features of that room. It may not seem important, and you may be thinking that no one ever looks up and inspects the lighting, but the type of lighting used in a room is very noticeable, especially to people who are sensitive to bright lights.

The benefit of LED lights, in comparison to fluorescent lights which are usually used in most rooms as a cheap and bright lighting solution, is that they aren’t harsh. LED lighting solutions are a softer kind of lighting, suitable for all kinds of rooms, no matter the room’s use.

In an office environment, LED lights offer an alternative to over-bright fluorescent lights. LED lights have also been revealed to have positive health effects and improve productivity. Eyestrain is one of the leading causes of stress in the workplace, because it creates a negative physical reaction in the body. Poor lighting (lighting that is too dim, too bright, or doesn’t cover enough of a work area) can contribute to a casual loss of work due to eyestrain and discomfort.

Studies have shown that work productivity can be increased by using gentler LED lighting. Proper lighting is essential for efficient work from employees and improving employees’ moods at work. Bad lighting often makes it difficult to concentrate.

Similarly, lighting in the home is just as important. Our homes are a place of comfort for us and are supposed to be seen as inviting (especially when compared to other establishments we may use during any given day). LEDs come in a range of brightness options, including lights that are warmer in color. When you’re deciding what kind of LED lighting to get for your home or office, you may specifically consider BAA LED Tubes.

BAA LED Tubes are one of the leading types of LED lighting that you can purchase. Because LEDs don’t burn out, you’ll have the advantage of thousands of hours of lighting before they might need to be replaced. BAA LED Tubes usually function for around 10 to 20 years before they need replacing, which makes them one of the best lighting solutions, even within the range of LED lighting available today.

You can tell that an LED light needs to be replaced when it starts dimming, but the majority of the time, you can leave an LED light on for 8 hours a day with no issues. They won’t affect your electricity bill as badly either, because they’re energy efficient and energy saving.

BAA LED Tubes, like other LED lighting solutions, are shock-resistant, and great for all rooms of the home or office. If there’s somewhere you can switch to LED lighting, BAA LED Tubes are for you.

Your home is your sanctuary.

After a long day’s work, you just want to put your feet up and spend time alone or with family. Your home is a place that should renew your spirits and rejuvenate you when your energy has been zapped from doing things outside.

The setting in your abode must then be perfect. It should give you a sense of calm, security and joy. There are many factors that contribute to this ideal environment, and one of these is proper home lighting.

See the light

Light, whether natural or artificial, has many benefits. Sunshine has restorative powers for the mind and body, over and beyond giving people a healthy dose of Vitamin D. Lighting fixtures beautify and add radiance to a home. It can also be a helping hand in providing security to your property.

It is only natural that you would want to maximize these advantages. Here are some tips to shed more light on how you can do so:

1. A sunny disposition

Architects and designers will most likely recommend that you incorporate lots of natural light in through windows, glass doors, skylights, or even sunrooms. This is because aside from aesthetics, it also has several other advantages.

Letting the sunshine in creates the illusion of space by making it appear larger. It also keeps mold and mildew growth at bay, keeping you and your family healthy.

When speaking of health benefits, regulated sunshine exposure has been found to lower the risk of depression among adults and children alike. Since it has also been found to help people become healthier, happier, calmer and more productive, sunshine has been used to regulate some conditions like Seasonal Affective Disorder (SAD).

2. Mirror, mirror

You might not use it to look into the future, but mirrors play a good role in enhancing your home’s interior lighting. Aside from checking if you still look good, mirrors also have functional and decorative purposes.

Hanging a mirror to reflect natural light in the sunroom, for instance, can make the room look brighter. You can also place a huge mirror at the end of a hallway, thereby creating an illusion of a wider, more spacious area.

Strategic placements of mirrors in the house can also be used to view another room. This is just like how they did it in the past, when smartly placed mirrors are used as a spyglass of sorts to check who’s at the front door.

3. Kaleidoscope

It is a common misconception to bathe your rooms in bright lights all throughout. Expert light consultants suggest utilizing multiple sources of lights in a room. You need to consider the various uses of an area so you can decide what types of lighting fixtures to fit.

Proper selection of light sources and knowing how to diffuse them can contribute to a well-lit room. Opt to layer and blend your light to improve the look and functionality of a home space.

As a basic guide, you can follow these recommendations:

  • Ambient lighting:  For general illumination (e.g. chandeliers or recessed canister lights)
  • Task lighting: Designed for specific task at hand (e.g. LED strips for kitchen under-cabinets for easier food preparation or a lighted makeup mirror)
  • Accent lighting: Focuses light on a specific area in a room to create drama or attract attention (e.g. sconces, track lights, flood lights, or LED downlights that may be used to highlight art and other artifacts or light a stairwell or hallway)

Fifty shades

Dimmers are a non-negotiable option, according to home lighting experts. Aside from helping with energy consumption, they are necessary to adjust the brightness of the light fixtures in a room.

Multi-purpose rooms benefit greatly with the use of lighting dimmers as it allows you to set the mood for a specific activity. You can turn it up when you’re sewing, for example. Then you can turn it down for a more subdued feel when you’re entertaining guests for dinner.

A light bulb moment

Not all bulbs are created equal. Understanding the different types of bulbs and their wattage will considerably help you decide where to use them.

Consider the function of the room and choose the corresponding lighting fixture. Is it your home office? A bathroom? Designers nowadays shun fluorescent lights, saying that they can lead to off colors and can cause fatigued eyes. Instead, they suggest using dimmable LED light bulbs or the like.

You can take note of the following color temperatures and lumens:

  • 2700K and 3000K are warm white (yellow); 2700K is warmer (more yellow)
  • 4000K – Tinge of yellow
  • 5000K – Pure white
  • 6000K – Tinge of blue

Note that:

  • For general use at home, 3000K (warm white) is recommended while 4000K or 5000K are recommended for bathrooms and laundry rooms.
  • If you’re looking for brightness, bulbs with around 600 lumens can give off light comparable to that of a 60-watt incandescent lamp.

Out of the dark

With a plethora of options in the market, choosing the appropriate light for your home is not a problem. Proper consultation with your interior designer or a home lighting advisor can do wonders for home illumination.

Impeccable lighting choices can literally light up your life, making your home the ultimate dwelling for rest and relaxation. It is time to step out of the shadows and embrace the positive vibes that good interior lighting can bring.

Ambient Table Light Large

Today we’re taking a look at an interesting product just launched on Kickstarter. Stephen Co from Canada has invented this beautiful lamp that uses 60 LED lights to create a so called Persistence of Vision. Combined with a steady stream of water set to vibrate at a certain frequency, changing the LED’s frequency results in various reactions from the water based on these frequencies.

The result is stunning and very futuristic:

By continually updating the frequencies it is possible to create unique and  awesome patterns in the water stream, and when illuminated by the RGB LED’s results as the one above becomes easy to achieve. And some of the possibilities are mind-bending such as the possibility to have the water flow upwards like so:

Besides being a very cool and visually stunning gadget, the technological achievements on this product are commendable. Aquarius has been built to fit in most homes, with a slim profile that doesn’t take up much space and fits in the window sill. But perhaps most intriguing is the fact that it’s possible to prod and probe the water streams with ones bare hands to truly explore this stunning piece of art/lamp.

And if the water streams are too distracting it’s also possible to just use the LED lights as a mood setting device, accent light or even night lamp. In total there are 11 different settings, such as “Unicorn” which displayed a rainbow of colors, or “Chaos Theory” which randomly chooses the LED colors and water frequencies and thus provides something truly unique each time the program runs. The developer has plans to release many more of these patterns, or settings as the product matures.

Another awesome aspect of this product is the fact that it’s developed on open-source Arduino IDE technology. That means that programming capable users can even code their very own patterns, or integrate Aquarius with their smart home products, mobile phone or any other gadget or piece of tech they so wish.

Aquarius is priced at a very reasonable $249 CAD, which includes a fully assembled lamp, power adapter for both EU and US sockets, and the complete set of source files for the tinkering hobbyist. Should you wish to get your hands dirty and develop one yourself, for just $20 CAD you can get the full source code and design files to make your own in the shed.

Either way, check out the project on Kickstarter here – I know I will.
