There are lots of reasons why you might be seeing shadows on your TV. To name a few, some of the most common reasons for shadowing on your tv, are burn-in, a poorly mounted TV, or faulty cables. Shadowing mostly occurs when you leave a still image on the screen for a long period of time. So, remember to always turn your tv off when no one is watching.
The truth is, there’s no easy way to fix shadows caused by burn-in, so the best idea is to prevent it. If you haven’t left a static image on the screen but you’re still seeing shadows, your TV may have some installation problems
How does burn-in happen? A Burn-in usually occurs when you leave a still image, for a long period of time, on your tv screen. Still, images such as a paused DVD or menu screen will be the main reason. The pixels inside the panel become damaged and develop a memory for the colors they are displaying. Your tv will begin to display only those colors, developing a shadow of the still image even after you remove the image.
You can prevent this by never leaving your TV on a still image for more than half an hour. It’s always a good idea just to be safe. Plasma TVs, with their phosphor technology, are more susceptible to burn-in than LCD TVs that use liquid-crystal technology, especially during the first 200 hours of use.
Another thing you can do is to avoid playing video games with static boxes, on plasma TVs if possible. What does this mean? These are the type of video games that show your power levels on the tv screen while playing. Playing for long hours at a time can cause the static boxes to burn-in.
Another thing is, to stay away from the black bars that appear when watching a widescreen movie. These days, most DVDs will give you an option to watch a full-screen version. If you do not have these options, change the TV’s aspect ratio through the picture menu until the black bars disappear. Black bars can leave shadows along the entire top and bottom of the TV screen.
Not a lot of people realize this, but if your tv is poorly mounted to a wall, shadowing may occur. Why does this happen? A poorly mounted tv’s wait will not always be shifted as it should and this may damage your TV’s pixels. Also, check whether TV is running in Power Saving Mode. Always follow the manufacturer’s instructions when mounting your television to a wall.
Are you someone that prefers to have your TV sit on the floor or on an entertainment center? There is no problem with this. With this said, always use the model’s mounting stand. Do not put the tv directly on the floor, the weight of the TV could compress lower pixels, causing a shadow effect at the bottom of the screen. Samsung tv screen

Something that happens a lot with cable boxes and TVs, is incompatibility issues. This may lead to shadowing. This problem often presents when you are pairing up a newer TV with an older cable box. What you can do, is update your cable box’s firmware to try to resolve the problem; some cable providers make firmware updates available online, others will send updated firmware to you and some will send out a repair person to update the firmware.
Using an HDMI cable with external devices can sometimes result in a shadow image appearing on the LCD screen. This is often not because of the cable directly, but maybe because of the external device’s video output settings and the use of an HDMI cable, more than likely the LCD panel is going bad. You can try changing the output settings on the external device or using a different type of cable, such as a component cable.

There are many reasons why dark black spots appear on the TV. But in most cases, their presence indicates damage to the matrix. And it doesn’t have to be mechanical. It is possible that the diffuser peeled off due to a manufacturing defect. And sometimes a dark spot on the TV can be eliminated by yourself! But in most cases, you have to seek help from an authorized service center of the manufacturer.
The basis of any modern TV (and monitor too) is a matrix. And it consists of several layers, in particular:Polarizing filter . Adjusts the transmission of light emitted by the backlight.
External polarizing filter . If it is missing, then instead of the image on the screen there will be only a dark gray background. Even if the layer of liquid crystals, as well as the backlight, function properly.
Also behind the matrix is an LED backlight. It is placed evenly over the entire diagonal plane of the TV. As a rule, this is an LED strip, where each element is connected in parallel (in some TVs it also happens in series, but this design is usually not used now).And LEDs also have their own operational resource (on average – from 30 to 50 thousand hours).
failure of the video chip (graphic processor, which is responsible for processing the digital signal, converting it and outputting it to the liquid crystal matrix).
Experts say that they can be provoked either by mechanical damage to the TV (impact on the matrix), or sudden voltage drops (in particular, exceeding its permissible value, over 230 – 250 Volts). Therefore, if the current in the home electrical network is not stable, then it is recommended to connect the TV through an external voltage regulator – this really helps to extend the operational life of the equipment.
Indicates an open circuit supplying one of the liquid crystal zones. It is impossible to repair such a breakdown. There is also always a risk that such spots will increase in size over time. That is, with a probability of 95%, the matrix will soon become unusable. It should also be noted that operating a TV with a damaged mechanically damaged matrix is not a good idea. There is a possibility that there is a short circuit between the supply circuits of the matrix, which will also lead to the failure of the inverter, or even the GPU. Repairing such breakdowns is impractical. That is, in the future you will have to purchase a new TV to replace the old one.
Failure of the inverter, which is responsible for supplying current to the backlight . In this case, the LED may initially not work only in a certain zone (for example, in the upper left corner). But in the future, other lighting zones will definitely be de-energized.
It looks more like a blackout zone with a corresponding halo rather than a separate dark spot. But at the same time, if you shine a powerful flashlight on the darkened part, you will notice that the image is displayed normally on the liquid crystal matrix. It just doesn’t light up. You should not do something on your own, it is better to contact an authorized service center for help as soon as possible. It should also be noted that if the backlight is damaged, it can periodically recover on its own. But this is a short-term effect. It is only additional confirmation that there is a violation in the supply circuits of LED strips.
In principle, the causes of spots for almost all TVs are the same, since the structure of the matrix and the principle of displaying the image are similar. But there are a few exceptions:On Samsung TVs with AMOLED matrices, dark spots may indicate matrix “burn-in”. There is no backlighting, as each pixel is technically an organic LED. At the same time, the spots look like an afterimage (they are often called “ghosts”).
Dark spots on the LG TV screen are sometimes the result of a software glitch! More precisely, because of the violation of the AVI and MPEG4 codec coding technology. In such cases, a banal firmware update using the built-in tools of the TV itself helps. With this problem, dark spots appear in different places every time you turn it on, without any cyclical order.
In very rare cases, dark spots disappear on their own over time. This happens if they appear due to delamination of the polarization layer with a slight overheating of the matrix. But this is about 0.5% of all cases. In other situations, a visit to the service center is required. And the faster, the better. How can the risk of stains be minimized? The following recommendations must be followed:by any available means to level possible mechanical damage to the TV (for example, if there are small children in the house, then it is better to place the TV on the wall at a height of at least 1.5 – 1.7 meters);
The Hisense U8H matches the excellent brightness and color performance of much pricier LCD TVs, and its Google TV smart platform is a welcome addition. But it’s available in only three screen sizes.
The Hisense U8H is the best LCD/LED TV for most people because it delivers the performance of a much pricier TV yet starts at under $1,000, for the smallest (55-inch) screen size. This TV utilizes quantum dots, a full-array backlight with mini-LEDs, and a 120 Hz refresh rate to deliver a great-looking 4K HDR image. It’s compatible with every major HDR format. And it’s equipped with two full-bandwidth HDMI 2.1 inputs to support 4K 120 Hz gaming from the newest Xbox and PlayStation consoles. Add in the intuitive, fully featured Google TV smart-TV platform, and the U8H’s price-to-performance ratio is of inarguable value.
Chief among the U8H’s many strengths is its impressive peak brightness. When sending it HDR test patterns, I measured an average brightness of 1,500 nits, with peaks just north of 1,800 nits (a measurement of luminance; see TV features, defined for more info). To put that into perspective, consider that the 65-inch version of our budget 4K TV pick (the TCL 5-Series) typically costs around half as much as the 65-inch U8H but achieves only around 30% to 40% of its brightness. On the other side of the coin, the 65-inch version of our upgrade pick (the Samsung QN90B) costs almost twice as much as the 65-inch U8H, but it achieves only nominally higher brightness. Adequate light output creates convincing highlights and image contrast and (when necessary) combats ambient light from lamps or windows. It is a necessity for any TV worth buying—especially if you hope to watch HDR movies or play HDR games—and the U8H simply outpaces most TVs in its price range (and some in the next price bracket up, too).
Key to this functionality is the U8H’s employment of mini-LED backlighting with local dimming, which allows this TV to produce very bright light while still maintaining satisfyingly deep black levels that are typically free of blooming (or light bleed that’s visible around bright objects against a dark backdrop). This not only ensures impressive image contrast, it also makes the U8H a viable choice for most rooms, whether they’re brighter than average or dimmed down like a movie theater.
That’s not to say the U8H has pixel-precise light control—it’s not an OLED TV, after all—but it does a terrific job most of the time. In fact, in our tests, the U8H bested last year’s upgrade pick, the Samsung QN90A, in certain scenarios: The intro to Guillermo del Toro’s Cabinet of Curiosities on Netflix features the filmmaker against a pitch-black backdrop. Though last year’s QN90A failed to maintain perfect control over dimming elements during this scene (the black backdrop brightened distractingly once a sufficient amount of brighter content appeared on screen), the U8H did not. (For the record, the newer QN90B also passed this test.) The U8H’s mini-LEDs also help the screen look uniformly bright: Although the U8H is still not as good as an OLED TV in this respect, it shows very little indication of being a backlight-driven display, even during tricky scenes with large swaths of dim lighting.
The U8H’s brightness, black-level integrity, and local-dimming abilities make this an excellent TV for watching HDR content. The U8H is capable of playing HDR content in all of the major formats (HDR10, HDR10+, Dolby Vision, and HLG), but when it comes to impressive HDR, what’s under the hood is much more important than format compatibility. The most crucial thing for good HDR is high brightness and deep color saturation, and the U8H’s quantum dots achieve the latter. It’s not as simple as just having quantum dots, however: While many TVs (even the budget options) have quantum dots nowadays, what is often not taken into account is that brightness directly affects color saturation. For example, both the 2022 TCL 6-Series and the Hisense U8H are equipped with quantum dots, mini-LED backlights, and local dimming. But because the U8H is notably brighter than the 6-Series, it also achieves a higher total color volume. During our color-volume testing, the U8H exhibited color ranges at more than 100% of the DCI-P3 color space (the range of color needed to properly display HDR content), and it is capable of roughly 10% more total color volume compared with the 6-Series.
What does this mean in real-world terms? It means that the Hisense U8H truly excels as a modern 4K HDR TV, whether you’re watching the latest episode of Rings of Power or playing Overwatch 2. While watching HDR content side by side on the U8H and on our upgrade pick, the Samsung QN90B, I was truly surprised by how similar they looked at times, given that our upgrade pick is much more expensive. That said, though the U8H achieves impressive results where light output and color volume are concerned, it also exhibited some occasional video processing and upscaling issues (see Flaws but not dealbreakers), which videophiles and AV enthusiasts may take umbrage with. But in general, the picture quality punches well above its weight, metaphorically speaking.
And thanks to Hisense’s inclusion of Filmmaker Mode, it’s easy to rein in the U8H’s brightness abilities for a more-subdued and filmic experience in a darker room. Our measurements revealed that this mode has a very accurate white balance, mostly accurate colors (green is a bit oversaturated, but not egregiously so), and a perfect “dark room” gamma (which controls how quickly the video signal transitions from dark to light). Additionally, the TV’s 120 Hz refresh rate means it can play Blu-ray discs at 24 fps without the judder that’s usually present on TVs with 60 Hz refresh rates.
The TV’s higher refresh rate also reduces motion blur in faster-moving sports and allows for smoother, more stable motion in games. Two of the four HDMI inputs support 4K gaming at 120 Hz. The U8H measured low input lag while playing in 4K resolution, and Hisense’s helpful GameZone setting in the picture menu allowed me to confirm the presence of 120 Hz playback and variable refresh rate during games.
The onboard Google TV smart platform is another feather in this TV’s cap. As usual, however, it will be much more satisfying to use if you have a Google account and already take advantage of Google’s connected services, like Photos. The experience of navigating the TV’s smart features—scanning QR codes to sign into apps, using the onscreen keyboard, and browsing your Google Photos to set a photo as a screensaver—was very satisfying in terms of responsiveness and speed. Powering on the TV and booting into an app took just seconds. The included Bluetooth remote is also equipped with a handy “Hey Google” button, allowing you to pull up Google’s assistant and use voice commands to search for content or set a reminder. If you have multiple users with their own Google accounts, you can designate separate profiles (attached to a Gmail account) so that each user can customize the experience to their liking, as well as access their own Google Drive or Photos. While some reviewers have reported instances of momentary freezing while using the U8H’s platform, I didn’t personally experience any instances of slowdown that were egregiously worse than with any other smart-TV platform.
In terms of design, the Hisense U8H is not as svelte as our upgrade pick, but it’s plenty sturdy and doesn’t look or feel cheap. Two narrow, metal feet jut out from beneath the panel and steadily hold the TV. They can be attached in two separate spots, either closer in toward the middle of the panel or out toward the edges, to account for different-size TV stands. The feet are also equipped with cable organization clasps—a nice touch for keeping your TV stand free of cable clutter. Though the TV is primarily plastic, its bezels are lined with metal strips, providing a bit more durability in the long run. I moved it around my home, and it was no worse for wear, but we’ll know more after doing some long-term testing.
The Hisense U8H has some difficulties with banding, or areas of uneven gradation, where transitions that should appear smooth instead look like “bands” of color (sometimes also called posterization). Like many current 4K HDR TVs, the U8H uses an 8-bit panel rather than a 10-bit panel, which affects the color decoding and color presentation process. This is usually relevant only with HDR video and games. When playing games on the PlayStation 5 and Xbox Series X, I saw a few instances where the content wasn’t rendered correctly and displayed ugly splotches of color on the screen. However, this almost always occurred during static screens (such as a pause menu or loading screen); I rarely spotted it during actual gameplay. Hisense has stated that it would address the problem in a future firmware update, but at the time of writing it was still present. This is a flaw that may give dedicated gamers pause, but we don’t consider it to be a dealbreaker for most people.
I also saw occasional instances of banding with TV shows and movies, though they were few and far between. The U8H isn’t the best at upscaling sub-4K content, so videos with a 1080p or lower resolution looked a little soft. You can get better overall video processing and upscaling by springing for our upgrade pick (this is one reason it’s more expensive, after all).
Although the UH8 TV has four HDMI inputs, only two of them are fully HDMI 2.1–compatible. And one of those is designated as the eARC input (intended as an audio connection for a soundbar or AV receiver connection). So if you’re pairing an external audio system with the U8H, you may have only one input remaining that can support HDMI 2.1 features like 4K 120 Hz playback, variable refresh rate, and auto game mode; this could be a dealbreaker if you own more than one current-gen gaming console. If you’re in that boat, you may want to splash out some extra dough for our upgrade pick. Additionally, folks using pre-HDMI source devices—like the five-cable composite connector with green, red, blue, and red/white audio inputs—should be aware that this TV requires an adapter to allow those devices to connect, and an adapter is not included in the box.
Finally, like most TVs that use vertical alignment (VA) LCD panels, the U8H has a limited horizontal viewing angle, which may be a bit annoying if you’re hoping to entertain a large crowd. Our upgrade pick uses a special wide-angle technology to address this.
If you’re watching in a darker room and want the most accurate picture you can get—preserving the director’s intent—select the U8H’s Filmmaker Mode as your picture mode. In a brighter room, we recommend the Theater Day picture mode. In either case, you should go into the backlight settings, disable the automatic light sensor, and set the backlight to your personal preference. This is true whether you’re watching SDR or HDR content.
For gaming, use the game picture mode (the TV should switch into this mode automatically when paired with the newer game consoles), and then go into the Gaming submenu to make sure the right settings (VRR) are enabled. We recommend leaving the HDMI setting in “auto,” unless you notice that your game console is incorrectly identified.
After a long, hard day, you finally sit down to catch up on your favorite show. But when you hit the power button on your remote control, your TV screen stays black! You try pressing the remote’s power button again and again from every angle, but still, your TV has no picture. If this sounds familiar, you’ve likely fallen victim to one or more TV screen issues.
What causes a TV screen to go black? Software issues, loose connections, or backlight problems are usually behind black TV screens. Learn about each of these causes and get tips for troubleshooting them so you can get back to relaxing with your favorite TV shows, movies, and video games.
If your TV screen is black and there’s no sound, you’ll want to check for an LED light or a small indicator light that tells you the TV has power. If there is no power to the TV while it is plugged in, there may be an issue with the outlet or fuse box in your home. However, if the TV is on but the screen is black, the problem could lie with your TV’s software.
Unplug the TV from the wall, and, if possible, remove the power cord from the back of the TV to perform a soft reset. Wait 30 seconds, and plug the TV back into a working outlet to test it again. If you’re still having screen issues, you might want to bring in an expert — they’ll know how to fix your TV’s black screen.
If your TV screen goes black but the sound still works, the first thing to check is the input source to ensure it is turned on and operating correctly. This includes external devices like cable boxes, video game consoles, laptops, and streaming devices. Once you’re sure the input source is working properly and you have the right input settings, check the cable connections. In many instances where the TV screen is black but the audio works, poor cable connections could be the issue.
Whether you’re working with an HDMI cable, RCA (usually yellow, white, and red cables) set up, or another type of connection, you need to ensure the cables are seated properly and firmly into their connection ports. With a good connection, the cable shouldn’t feel loose or easily disconnect when pulled on or moved around. If all your cables have a snug fit but the problem persists, try connecting the device to another TV. If your TV screen is still blacked out, you may need new cables.
Some TV displays, such as LCD screens, use a backlight to illuminate the picture. If the backlight burns out or stops working, it will result in a blank TV screen.
To check your TV’s backlight, make sure your TV is on. Then, turn off the lights in the room and shine a flashlight on the screen. If you can see a picture with the flashlight, then your TV’s backlight is likely burnt out.
While you might be eager to learn how to fix a black-screen TV, a broken backlight does not come with an easy solution. The backlight will need to be replaced, and it’s best to get help from a professional with this task.

Screens can scratch easily, and even paper towels and tissues contain fibers that can do damage. “Your best bet is to use a soft, anti-static microfiber cloth—the kind used to clean eyeglasses and camera lenses—and wipe in a circular motion,” says John Walsh, who cleans more than 250 TVs a year in his role as a CR photographer. (Some TV manufacturers will include a cloth for this purpose.) “Gently wipe the screen with a dry cloth to remove dust and other debris, but don’t press too hard,” he says.
You may also want to wipe down the TV’s cabinet, and make sure dust isn’t clogging the vents that help dissipate heat. If the TV is on a stand and not tethered to the wall, Walsh suggests cleaning with one hand while supporting the TV with the other to prevent the set from tipping over. However, CR strongly recommends anchoring all stand-mounted TVs using anti-tipping straps designed for this purpose.
If there are hard-to-remove stains, you can dampen the cloth slightly with distilled water and gently clean the screen. Don’t spray water directly onto the screen; that could cause a shock or component failure if water seeps into the inner workings of the set.
For the most stubborn stains, you can try using a solution of very mild dish soap highly diluted with water, once again applied to the cloth and not to the TV itself. (As a guideline, Panasonic used to recommend a 100:1 ratio of water to soap.) LCD screens, in particular, are very sensitive to pressure and can scratch easily, so don’t press hard.
