sony bravia lcd screen problems in stock
this tv had a bad screen ( ghosting and flickering). This tv is well know for this problem. most of the time there are 3 major causes : bad T CON board, loose flat cables or a bad LCD screen) also a bad lvds connector can cause some problems so also check the connector real good as well the cable.
The black screen of death (BSOD) is a relatively common issue with flat screen TVs with LCD panel screens. In a lot of cases, they are easily diagnosed and fixed quite affordably. Replacement parts are usually easily sourced unless there is suddenly an unusually high demand for them, in which case prices may increase.
Unfortunately, even the higher end spectrum of the TV brands like Sony get struck down by this annoying electronic malady. And many owners, at some point, do find themselves standing in front of a Sony TV screen that has suddenly gone dark/black, with no more pictures/images appearing.
If your Sony flat screen TV stops producing images on the screen and goes black, first step is to determine if it also stopped producing sounds. You can do this by shuffling to input channels which you are certain should produce sound (i.e., streaming a video content, or running a DVD player, etc.).
If the LED backlights are working, you there is likelihood that you have a T-Con board issue on your hands. Replacing the T-Con board, a relatively inexpensive replacement, will usually fix this problem if the unit is producing sound. If the unit is not producing sound through the speakers AND pictures on the screen, there could be a problem with the T-Con board and/or the main board.
If the LED backlights are not working, or if you are unable to confirm if they are working, the next step is to do the flashlight test on the screen. By turning on the TV and shining a flashlight on the screen, you can check if the LCD panel is creating images or not. If the LCD panel is producing images but the LED backlights are not working, you should be able to make out images on the LCD panel when you shine a flashlight beam on the screen. An LCD/LED TV requires an LCD panel to produce the images and suitable (LED) backlighting to work as intended.

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.
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 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.
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.
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.
Of course, sometimes, the TV is beyond repair and you should replace it instead. If the screen is broken or the TV doesn’t turn on no matter what you do (or if the sound stopped working completely), it’s time to check out a new set.
Few things are as off-putting as a dead pixel in the middle of your screen. Whether these dots are black or green, they’re incredibly inconvenient. Before jumping to the worst conclusion, however, you might want to make sure that it’s indeed a dead pixel, not a stuck one.
You may also want to check out if the problem is, indeed, with the screen. You’d be surprised at how often a small piece of dirt or dust can look like a dead pixel, so clean the screen before assuming you’re dealing with a big problem. Then use the screen to try games or connect it to your computer; if the pixel disappears on a specific media, then the issue could be the connection.
If the colours on your screen appear distorted, then your TV might be malfunctioning. Traditionally, this issue tends to occur gradually, meaning that you might not notice any difference at first. This is due to the common factor that one colour tends to weaken at a time; therefore, no obvious changes happen overnight.
If your screen starts to display bars and lines, this tends to indicate that there is an issue with a connector. This can occur when something magnetic has been placed near the TV and, in turn could mess with the picture quite considerably, even potentially de-magnetising the screen.
The issue can be due to cables that have become loose inside the screen as well, which is an easy fix, although it may require a professional because the TV may have to be opened.
This is often known as screen burn-in, although this definition is not entirely accurate. Screen burn-in is a more serious issue that involves the permanent degradation of the screen and occurs by leaving a static image on a screen for a long time.
Image retention, while frustrating, can be more easily fixed. Image retention occurs when the image sticks on the screen even when you change the channel or input different media – this tends to only appear for a few moments.
You may be able to do something about this by adjusting the levels of brightness and contrast on your TV and playing different types of content to see if the problem goes away. You can also enable your TV’s Pixel Shift feature; when this feature is turned on, images on the screen move a bit to vary the pixels used. Pixel Shift is often included in modern sets and might clean out the phantom image.
Another common problem is when the image displayed on the screen appears to be fuzzy or blurry. The smaller details tend to become lost and the quality of the picture displays poorly, very quickly taking your enjoyable movie experience to one of discomfort and stress.
If the TV is on but the picture is faded on some areas of the screen, it’ll be difficult for you to actually enjoy the content. You may try to ignore the stain-like mark but there is no denying that this will impact your experience. Faded spots are not that rare and can be accompanied by other serious issues, like your image fading to black after you’ve turned the TV on.
