The LCD panel does not have to have cracks to fail. The issue can be related to the circuit board (LCD controller board) that is connected directly to the panel via some very thin ribbon cables. Those cables are "glued" to the LCD panel. you can check and push on those ribbon cables and see if that changes it. If it restores the picture even for a brief moment you know it is the TAB , hence the panel , that has failed.
There are various panel technologies. Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used.VA
The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. They provide 18-, 24-, and 30-bit color, respectively.8 bits
Frame Rate Control (FRC) is a method, which allows the pixels to show more color tones. With quick cyclic switching between different color tones, an illusion for a new intermediate color tone is created. For example, by using FRC, a 6-bit display panel is able to show 16.7 millioin colors, which are typical for 8-bit display panels, and not the standard 262200 colors, instead. There are different FRC algorithms.No
The maximum number of colors, which the display is able to reproduce, depends on the type of the panel in use and color enhancing technologies like FRC.16777216 colors
The backlight is the source of light of the LCD display panels. The type of backlight determines the image quality and the color space of the display. There are various backlights such as CCFL, LED, WLED, RGB-LED, and etc.Direct LED

An inability to connect to the Internet is one of the most common smart TV problems, not just for TCL.And for the most part, the solutions to this issue are the same for most TV brands.
TCL has options for TVs with either Android and Roku for the operating system. They have dedicated TV models that have one of these systems installed.
TCL"s lineup in the United States is usually smaller than other brands, and unlike other companies, their models are available for a few years. They have a few different series, including the XL Series, 6 Series, 5 Series, 4 Series, and 3 Series, and each series has models with different smart platforms. For example, the 6 Series includes the 2021 R646, which uses Google TV, and the 2020 R635 has Roku TV, so for each series, you can get the model with the smart platform you prefer. They release new models with each platform in alternating years, and although not much is known about their 2022 lineup, the TCL 4 Series/S445 comes with Roku.
TCL"s model naming scheme is a bit confusing and inconsistent. The XL and 6 Series lineup start with an R, while the other lineups start with an S. Next is the number to indicate the series, and the last two numbers tell you which platform and year the model is from. Google TVs end in a 4 or 6, and Roku TVs end in a 5. For example, the S445 is a 4 Series model with Roku from 2022, while the S434 is a 2020 model with Google TV.
While the majority of TCL"s TVs use Roku, there are a few from 2021 that use Google TV. They"re both great smart platforms, and choosing one of the other comes down to personal preference. Generally speaking, Roku is easier to learn and feels quicker than Google TV, but Google is more customizable, and the Google Play Store has even more apps.
Some TCL TVs support voice controls, either from the advanced remote or the remote app, but they only support basic commands. You can launch certain apps through voice control and search across multiple apps for content. Unlike some TVs, you can"t control the TV"s settings through voice controls.
This is where Google TV has an advantage because the remote supports voice control, and it"s also compatible with other Google devices, so you can easily open apps and stream your favorite shows. Some of TCL"s Google models even have a mic built into the TV.
The Roku TVs come with a small remote, which isn’t a bad thing since it"s very comfortable and responsive. The TCL branding is impressively minimal, and much like the interface, it’s a carbon copy of the ones you can find with the Roku boxes.
