Find out why the standby light on your Samsung TV is flashing and how to address it
When your Samsung TV is functioning correctly, the red standby light remains off when the TV is off, and on when the TV is powered on. But what should you do if the light flashes while the screen remains dark? A flashing standby light typically indicates an issue with your Samsung TV's power supply, though it could also stem from a software glitch or an HDMI connection problem. In this guide, we'll walk you through the most common reasons for a blinking red light on your Samsung TV and how to resolve them.
Key Points to Remember
- You might resolve the issue by plugging your TV into a different outlet or power strip.
- Attempt power cycling the TV: unplug it, wait at least 30 seconds, then plug it back in.
- Ensure that all HDMI input devices are functioning correctly.
- If these common solutions fail, consider seeking professional repair for your TV.
Steps to Take
Attempt using a different power outlet for the TV.
A flashing red light often signals a power supply issue. A straightforward remedy is to plug your TV into an alternative power source. Disconnect your Samsung TV and wait for 30 seconds, then attempt plugging it into another outlet that is known to be functional. Power the TV back on to check if the problem persists.
- If your TV is connected to a surge protector or power strip, attempt resetting the power strip. Disconnect all devices plugged into it and press the reset button on the strip. Subsequently, plug your TV and other devices back in.
- If alternative appliances in the vicinity are also malfunctioning, you may have a tripped circuit breaker. Locate your breaker panel or fuse box and reset the breaker.
Perform a power cycle or cold boot.
Power cycling can rectify issues by resetting your TV’s primary board. If connecting your Samsung TV to a functional outlet does not resolve the issue, a cold boot might be beneficial. This action can help resolve problems stemming from launch setting glitches or interrupted software updates. To power cycle your TV:
- While the TV is plugged in and powered on, press and hold the power button on the remote until the TV shuts off and then restarts.
- Alternatively, unplug your TV from the wall, wait for 30 seconds, and then reconnect it. Turn on your TV to ascertain if the issue has been resolved.
Replace the power cord if it’s damaged.
Inspect the power cord for any noticeable nicks, bends, or damage. Damage to your TV’s power cord could hinder its proper functioning. If you observe any issues with the cord, you might need to purchase a replacement.
- Even if the cord appears undamaged, it could still be the root of the problem. Try plugging another device into the same outlet to determine if it functions. If it does, the problem may lie with your cord or the TV's internal components.
Look for issues with HDMI input.
Disconnect any devices connected to your TV’s HDMI port(s). Sometimes, a flashing red standby light can be attributed to an HDMI source or connection issue. Try unplugging all devices connected to your TV’s HDMI ports (such as a game console or Blu-ray player) and check if the problem persists. If your TV powers on normally after removing HDMI devices, follow these troubleshooting steps to ensure proper functioning of your input source:
- Disconnect the HDMI cable from both the device and your TV, then reconnect both ends.
- Ensure that the input device is powered on by pressing its power button.
- Verify that you have selected the correct HDMI source on your TV. For instance, if your device is connected to HDMI port 1 but HDMI 2 is selected as the source, the flashing red standby light may indicate no input from the selected source.
- Consider using a different HDMI cable to connect the device to your TV, as the current cable may be faulty or damaged.

Analyzing the blinking light patterns can offer valuable troubleshooting insights. Most TV blinking lights follow a pattern — either a specific number of blinks or color codes. The first step is to observe the blinking pattern and count the blinks. Then, turn to Google for potential solutions, which might include simple fixes or instructional videos. You might even discover the exact replacement part you need.
Reach out to Samsung if you suspect issues with the internal components.
Issues with LED backlights, capacitors, or the main board may be the cause. Unless you possess advanced technical skills, addressing these problems yourself can be challenging.

If the red light on your Samsung TV remote is flashing and you're unable to control the TV with the remote, try charging or replacing the batteries.
