Samsung TV Won't Turn On? What the Red Standby Light Tells You
When a Samsung TV won't turn on, the small red standby light tells you where to look. Samsung splits its troubleshooting into three cases: the light is on, off, or blinking. The first fixes are unplugging the TV for 30 seconds and moving it to an outlet you know works, without a surge protector. A light that keeps blinking after that is Samsung's signal to request service.
Quick answer
Check the red standby light first. If it's blinking, unplug the TV for 30 seconds, then plug it straight into an outlet you know works, not a surge protector. A steady red light afterwards means power is reaching the TV; if it still blinks, Samsung says something is wrong with the TV and to request service.
- 1.Unplug the TV for 30 seconds, then plug it into an outlet you have tested with another device, such as a lamp, without a surge protector in between.
- 2.Look at the red standby light: steady means the TV is getting power; still blinking means it's time to request service from Samsung.
What it means
The red standby light is the small red light at the bottom edge of the TV, where you aim the remote. In normal use it is on while the TV is off (the TV is in standby) and off while the TV is in use or has no power. Samsung's own troubleshooting for a TV that won't turn on is split by what that light is doing: on, off, or blinking.
Samsung also points out that a TV which looks off may actually be on and showing a blank screen. That happens when you are watching through an external input and the device on that input is off or not working, so check that before assuming the TV has no power.
A blinking light is the case that needs care. Samsung's steps for it are to unplug the TV, move it to an outlet you know works and drop the surge protector. If the light then stays on steadily, the TV is receiving power and the problem was the original outlet or the surge protector. If it is still blinking, Samsung describes that as a sign that something is wrong with the TV and sends you to request service. The Samsung articles cited here don't give a meaning for a particular number of blinks, so this guide doesn't either.
Common causes
- The outlet or surge protector isn't supplying power. Samsung says that if the standby light comes on steadily after you move the TV to a working outlet, the issue was the original outlet or the surge protector. It advises against surge protectors because they may eventually wear out and stop providing the voltage the TV needs.
- A problem with the power cord. Samsung lists the power cord next to the outlet among the things to check when the TV won't turn on.
- The TV is on, but the screen is blank. If you watch through an external input (cable box, console, streaming device) and that device is off or not working, the TV can look as if it hasn't turned on. Samsung asks you to make sure the external device is on and working.
- The remote control. Samsung includes the remote among the things to check. If the TV has power but ignores the remote, it never gets the command to turn on.
- A fault inside the TV. If the red standby light is still blinking after you have unplugged the TV and moved it to a working outlet, Samsung treats it as a sign that something is wrong with the TV and recommends requesting service.
Before you start
- Note what the red standby light is doing right now: on, off, or blinking. Every next step depends on it.
- If you usually watch through a cable box, console or streaming device, make sure that device is switched on and working.
- Check whether the TV is plugged into a surge protector or power strip instead of directly into a wall outlet.
- Plug another device, such as a lamp, into the same outlet to confirm the outlet works.
Fixes, from safest to last resort
Unplug the TV for 30 seconds
No data loss- 1Unplug the TV's power cord from the outlet.
- 2Leave it unplugged for 30 seconds.
- 3Plug it back in and watch the red standby light before you press any button.
This is the first step in Samsung's own troubleshooting for a TV that won't turn on. It doesn't change any settings.
Plug the TV into an outlet you know works, without a surge protector
No data loss- 1Test the outlet with another device, such as a lamp.
- 2If the TV was on a surge protector or power strip, take it off and plug the TV directly into the working outlet.
- 3Check the power cord while you're at it, at the TV end and at the plug.
- 4Look at the standby light. If it now stays on without flashing or blinking, the TV is getting power and the original outlet or surge protector was the problem. Try turning the TV on.
Samsung advises against surge protectors for the TV because they may eventually wear out and stop providing the voltage the TV needs.
⚠ If the red light is still blinking after this step, stop here and don't open the back of the TV to look for the fault: its internal power components can be dangerous to touch. Samsung's next step at this point is to request service.
Make sure the external device is on and working
No data loss- 1If you watch through a cable box, console or streaming device, turn that device on with its own remote or button.
- 2Check that the device itself is working (its own lights, its own display) and give the TV a moment to show the picture.
- 3If you hear sound but the screen stays black, see our guide on a Samsung TV that has sound but no picture.
Samsung notes that in some situations the TV is actually on but shows a blank screen. A steady red light that goes off when you press power is a hint that this is your case.
Rule out the remote with the TV's own controller button
No data loss- 1Find the controller button on the TV itself. Samsung documents turning the TV on and off with it, but its position varies by model; see our guide on finding your TV's hidden power button, or your user manual.
- 2Press the controller button to turn the TV on.
- 3If the TV turns on with the button but not with the remote, the remote is the part to check next. See our guide on telling whether the remote or the TV is broken.
If a menu doesn't match your TV
- On Samsung monitors and the Odyssey Ark gaming screen the standby light is blue, not red. The same on, off or blinking logic is what Samsung uses to split the troubleshooting.
- If you can't find the standby light or the controller button, Samsung's advice is to check the user manual for your model, since instructions vary between models.
- Own a 2024 Samsung OLED TV? Samsung US lists a separate support article, '2024 Samsung OLED TV does not power on', which links the problem to the SMPS (power board). Search for that title on Samsung's US support site.
- If your TV does turn on but switches itself off again, that is a different problem: see our guide on a Samsung TV that keeps turning off by itself.
When to contact support
Request service from Samsung if the red standby light is still blinking after you have unplugged the TV for 30 seconds and moved it to a working outlet without a surge protector. Samsung describes that as a sign that something is wrong with the TV. Have this ready:
- Your TV's model number. See our guide on finding your TV's model number if the label is hard to reach.
- What the standby light did before and after the outlet test (on, off or blinking), and whether the TV responds to its own controller button.
- Whether the TV was on a surge protector and whether another device works in the same outlet.
- Contact options depend on your country: Samsung US offers online chat and support through the Samsung Members app, and Samsung Gulf points you to its contact center and service centers.

Frequently asked questions
Samsung TV won't turn on, but the red light is on. What does that mean?+
A steady red light means the TV is in standby and receiving power. Check the device on the input you were watching (it may be off, leaving a blank screen), then try the controller button on the TV itself. If the TV turns on with that button, look at the remote next.
Why is my Samsung TV red light blinking and it won't turn on?+
Samsung's steps for a blinking light are to unplug the TV for 30 seconds and plug it into an outlet you know works, without a surge protector. If the light then stays on steadily, the outlet or surge protector was the issue. If it keeps blinking, Samsung says something is wrong with the TV and to request service.
Samsung TV won't turn on with remote: is it the remote or the TV?+
Press the controller button on the TV. If the TV turns on that way, the TV is fine and the remote needs attention; see our guide on telling whether the remote or the TV is broken. If the TV doesn't respond to its own button either, go back to the outlet and standby light checks.
Samsung TV won't turn on and the red light is off. What should I check?+
With the light off, the TV is either on with a blank screen or not getting power. Make sure any external device you watch through is on, then unplug the TV for 30 seconds and plug it into an outlet you have tested with a lamp, without a surge protector.
What do 2 or 5 blinks of the red light mean on a Samsung TV?+
The Samsung support articles cited in this guide don't assign a meaning to a specific number of blinks. What they do say is that a light that still blinks after the 30-second unplug and the outlet change is a sign of a problem with the TV, and the next step is Samsung service.
Can a surge protector stop my Samsung TV from turning on?+
It can. Samsung advises not to use one for the TV because surge protectors may eventually wear out and stop providing the voltage the TV needs. If the standby light comes on steadily once the TV is plugged directly into a working outlet, the surge protector or the original outlet was the cause.
Is my Samsung TV broken if it won't turn on?+
Not necessarily. Samsung's checks start with the outlet, the power cord, the remote and any external device, and a TV that looks off can be on with a blank screen. Only a red light that keeps blinking after the outlet test is described by Samsung as a sign that something is wrong with the TV.
