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.

- 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.

- 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.

- 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 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.

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. If that doesn't resolve the issue, remove the batteries, press and hold the Power button for 8 seconds to reset the remote, then reinsert the batteries and try again.
