How to Fix an LG 47LB6100-UG TV That Flickers On and Off After a Power Outage

If you own an LG 47LB6100-UG TV that flickers on and off after a power outage, you might be wondering what caused the problem and how to fix it. This article will explain the possible causes and solutions for this issue, as well as some recommendations for similar models that are affordable and reliable.

There are several factors that could cause your LG TV to flicker on and off after a power outage, such as:

• A loose or damaged input cable. Sometimes, the cable that connects your TV to the source device (such as a cable box, DVD player, or game console) can become loose or damaged due to the power surge or outage. This can interfere with the signal and cause the TV to flicker.
• Incorrect display settings. Your TV has various picture modes and settings that affect the brightness, contrast, color, and sharpness of the image. If these settings are not optimal for your viewing environment or source device, they can cause the TV to flicker. For example, if you have the backlight level too high or the energy saving mode on, you might experience flickering issues.
• A failing backlight. Your TV uses LED backlight strips to illuminate the screen. These strips can wear out over time or get damaged by the power surge or outage. If one or more of the LED lights fail, the TV will try to compensate by adjusting the brightness of the remaining lights, which can cause the TV to flicker.
• A faulty main board, power board, or T-con board. These are the internal components that control the power supply, signal processing, and image display of your TV. If any of these boards malfunction or get damaged by the power surge or outage, they can cause the TV to flicker or not turn on at all.

Possible Solutions

Depending on the cause of the problem, there are different ways to fix your LG TV that flickers on and off after a power outage, such as:

• Reseating your input cable. The simplest and easiest solution is to check your input cable and make sure it is securely connected to both the TV and the source device. You can also try using a different cable or a different input port on your TV to see if that solves the problem.
• Changing your picture settings. You can try adjusting your picture settings to see if that reduces or eliminates the flickering. You can access the picture settings by pressing the settings button (gear icon) on your LG TV remote and scrolling down to the picture menu. You can try the various picture modes to see if they fix the flickering issue, and you can also switch off the energy saving mode, as well as changing the panel brightness and gamma.
• Performing a power cycle or a pixel refresh. You can try resetting your TV by unplugging it from the wall for at least 30 minutes, holding down the power button on the TV for 15 seconds, and then plugging it back in. This can clear out any issues with the flash memory and reset the main board. If you have an LG OLED TV, you can also try performing a manual pixel refresh, which can help remove any image retention or lines on the screen. You can access the pixel refresh option by pressing the settings button (gear icon) on your LG TV remote and scrolling down to the OLED panel settings menu.
• Updating your TV’s firmware. You can try updating your TV’s firmware to see if that fixes any bugs or glitches that might cause the flickering. You can update your TV’s firmware by connecting your TV to the internet and accessing the software update option in the settings menu. You can also download the firmware file from the LG website and transfer it to a USB drive, which you can then plug into your TV and follow the on-screen instructions.
• Replacing the backlight, main board, power board, or T-con board. If none of the above solutions work, you might need to replace one or more of the internal components of your TV. This is a more complex and costly solution that requires some technical skills and tools. You can find the replacement parts online or contact a professional TV repair service. You can also watch some online videos that show how to disassemble and replace the parts .
