Quick Navigation
1. Unplug External Devices
If you have any external devices plugged into your TV, their glitching connections could cause your TV’s light to start blinking red.
Namely, external HDMI-compatible devices can glitch and can your TV to experience power problems, resulting in it being unable to turn on. This can sometimes happen when you’ve suddenly plugged a powered HDMI device into your TV without first adjusting your TV’s input to the correct source.
The easiest way to fix this problem is to unplug every HDMI device from your TV. Then, try to turn your TV on.
If it turns on successfully, you may try to change your TV’s input to the correct source before plugging your HDMI-compatible device back into your TV.
If this solution does not resolve the TV’s blinking red light, proceed to the next solution.
2. Power Cycle
Your TV’s power may have glitched, causing it to start up incorrectly. There could be something wrong with its power supply or one of the TV’s internal components may have glitched.
While power supply issues may sound serious, many of them are notoriously easy to fix.
To fix this problem, you will need to perform a power cycle. This will drain your TV of all its power before powering and turning it on again, giving the hardware a chance to work correctly.
First, turn off your TV so its LED indicator light turns a steady red. Then, unplug the TV from its wall outlet or power strip.
Now is also a good time to check that the TV’s power cable is clear of any tears or imperfections that may be preventing your TV from being properly powered.
You may also want to unplug any other devices connected to it.
Wait 30 seconds or so for the TV’s power to drain.
Then, plug the TV back into the wall outlet or power strip and power it on.
Check if the LED light has turned from a blinking red to a steady blue, indicating that the problem has been fixed. Now, you may plug your TV’s external devices back into their compatible ports.
If the light is still blinking red and the TV remains off, try proceeding to the next solution which discusses your TV’s power source as a possible cause.
3. Try Another Wall Outlet
There may be something wrong with the wall outlet you’re using to power your TV. It could be insufficiently powered or faulty, preventing your TV from turning on correctly.
So, try plugging your TV into a different wall outlet in your home. Please ensure that the wall outlet is close enough to your TV so that the cord is not being tugged on, possibly pulling your TV off of its entertainment unit or wall bracket.
You may also want to ensure it’s not plugged into an extension cord, power strip, or surge protector. All three of these power devices wear down over time and may eventually fail, causing the devices plugged into them to receive insufficient power.
Faulty extension cords, power strips, and surge protectors can mislead users into thinking that their wall outlet or TV are broken, as they’ll prevent electricity from reaching the TV. So, to ensure that you’re accurately assessing if your TV or wall outlet is faulty, it’s best to avoid using them.
If there isn’t another wall outlet near your TV, you may have to dismount it and move it next to the closest outlet to accurately assess the problem.
If your TV continues to display a red blinking light when plugged into different wall outlets without an extension cord, power strip, or surge projector, there may be something wrong with its internal components.
4. Send the TV for Repair
If you’ve tried all of the above solutions but are still experiencing problems with your Samsung TV, there may be something wrong with its hardware causing it to not power correctly.
Although uncommon, your TV’s power board or LED strips may have failed, preventing the screen from illuminating or powering. While this usually happens on older TVs, it can happen on relatively new units with faulty hardware.
Several Reddit users reported having this problem with their Samsung TVs and then later opened up their TVs to find internal components showing signs of damage.
Although these users discovered their TV’s damage by taking apart the unit themselves, we strongly recommend against this.
TVs have several components, such as their capacitor, that store massive amounts of electrical charge. If you touch these components without properly draining them of their power first, you could be electrocuted by lethal amounts of electricity that could instantly kill you.
So, to avoid a tragic accident, please contact Samsung customer support for more information on where to find reliable TV technicians.
You may also want to inquire if your TV warranty policy will cover the cost of repairs or replacement.
Bear in mind that taking your TV to a TV technical that is not affiliated with Samsung may void your warranty.
