You can read about their differences here. By using a backlight, LCD TVs use much less power than plasmas, which you can read about here. Also, LCD TVs tend to get much brighter than plasmas, making them more suitable for well-lit rooms. There are two main types of backlights used in LCD screens: CCFL and LEDs.

63 isn’t terrible but would be nice to see 100% backlight. You might need to change the led strips or computer chip for the backlight if this continues or gets worse. You won’t be able to take the tv apart it’s virtually impossible without creation tools ormachines to take the tv screen apart properly.

Replacing Vizio LED Backlight Strips. The backlights on TVs consist of strips of LED lights. If one of the lights in the strip breaks, the entire strip won’t work. It’s easier to replace the entire strip than it is to replace a single malfunctioning LED light. You can order a set of backlight LED strips for your exact TV model online.

4. Test with external devices: Connect an external device, such as a DVD player or gaming console, to your TV. If the external device displays properly, it suggests that the backlight is not the issue. 5. Shine a flashlight on the screen: While the TV is turned on, shine a flashlight at an angle onto the screen.

When the device turns off with only the backlight showing, please try to press these keys to re-initialize the display (Windows key + CTRL + Shift + B) and see if the display shows up again or try these keys to turn on the narrator (Windows key + CTRL + Enter), the narrator will then start to read the text on the screen.
@sailor_dan I despise not having a schematic but this is what we have to deal with. Anyhow. The LED driver board gets its signal from the main board. It is the main board that tells the power board to turn on and the LED Drive board to turn on as well. Measure the voltage on CN1 of the LED driver board.
I was just looking for a fix for this. I have the same model laptop running Windows 11 right now. If the display turns off for any reason, the keyboard backlight functions cease to work. The touchpad disabling function key also stops working.

Factory setting glitch: Occasionally, a glitch in the TV’s settings can cause the sound but no picture issue. Resetting your Samsung LED TV to its factory settings can help resolve this problem. However, keep in mind that doing so will erase any personalized settings or configurations. 5. In case the hotkeys are not working, try it as a combination with the Fn key ( Fn + F7, Fn + F3, and Fn + F4 ). But if you have a gaming model, use Fn with the up and down arrow keys. Check the keyboard light icon to identify yours. Some ASUS laptops even allow locking the function keys using the Fn + Esc hotkey.

Both types of displays use liquid crystals to help create an image. The difference is in the backlights. While a standard LCD monitor uses fluorescent backlights, an LED monitor uses light-emitting diodes for backlights. LED monitors usually have superior picture quality, but they come in varying backlight configurations.
If your backlight is working and you have sound, you most likely have a T-Con issue. If your backlight is working, but you do not have sound, you most likely have a main board issue. If your backlight IS working (but you DID NOT see images with the flashlight test) and you HAVE sound: Unplug your TV.

This morning the set was working fine, but after being switched off for about two hours and switched back on this afternoon, there is only sound and completely black screen. So the questions are the usual. Is this a complete backlight failure resulting in the backlight LED's requiring replacement.
