How to Fix Standby Light Flashing Red on Samsung TV

Consumers may encounter glitches on their Samsung TVs, which don’t turn on normally but flicker with red light. The issue occurs due to a bad power supply or issues with external connections.

If your Samsung TV screen has flashing or blinking red lights, there’s a likelihood that your TV’s static red light is turned off or the smart TV is on standby. This guide will enable you to analyze the Samsung TV flashing red light issue and provide you with viable instructions on how to resolve the issue.

What Causes Samsung TV Standby Light Flashing?

Below are some of the cause of light blinking red issue:

Poor Flow of Current

Poor electric current flow is one of the lead causes of blinking red light issue. For example, suppose electric current doesn’t flow evenly to all TV components due to power surge or shorting out. In that case, it may damage various components, including the TV’s power cord, LED backlight strips, or power board that converts the voltage to flow from the main power supply. In these scenarios, the blinking light indicates that your TV gets supplied more voltage or less power energy than required.

Faulty Power Capacitors

Another common effect of an unregulated power supply is blown capacitors. Capacitors are essential components in your Samsung TV since they hold and release electricity. However, if they are predisposed to excessive voltage, they can blow up and malfunction, eventually leading to a blinking red light.

Faulty Wall Outlets and Surge Protectors

Sometimes the issue may not result from your TV but rather from accessories that your TV is plugged into for power supply. For example, the wall outlet or surge protector might be faulty, leading to the standby light blinking red TV issue. After installing power surge protector devices on your smart TV, you need to ensure they are not faulty. Samsung TV standby light flashing issue occurs due to inconsistent voltage provided by the power surge device like UPS, limiting your smart Tv from powering on and blinking red.

Shorted LED Backlight Strips

Nowadays, most Samsung smart TVs have a backlight effect that makes the picture image clearer, better, and more visible. The TV’s backlight occurs due to LED light strips separately from the screen. Once the LEDs short out, you’ll encounter the problem of red-light blinking, and the TV screen might fail to work. So, there’s a need to replace them and restore the TV functionality.

Erroneous Input Source Selection

Your Samsung TV may fail to turn on if you’ve selected an incorrect input source. Lack of signal from the source may also lead to the blinking light issue.

Firmware Installation Issue

Firmware glitches could be another cause of standby light flashing red or no picture on Samsung TV. If you switch the Samsung TV off during the installation or update of the firmware or software, you will likely encounter the above issues.
