Start With the Basics
Before diving into complex troubleshooting, check these common culprits:
- Make sure the TV is plugged into a working outlet
- Verify the power cord is securely connected to both the TV and wall
- Check that any power strips or surge protectors are switched on
- Try using the power button on the TV itself instead of the remote
- Test a different wall outlet to rule out electrical issues
Perform a Power Cycle
A power cycle clears temporary glitches and often resolves startup problems:
- 1.Unplug the TV from the wall outlet
- 2.Press and hold the power button on the TV for 60 seconds
- 3.Plug the TV back in
- 4.Try turning it on

Check the Standby Light
The red standby light provides important clues about your TV's status:
- Solid red light: Your TV is receiving power and should turn on normally
- Blinking red light: This indicates a power supply issue that needs attention
- No light: Check power connections and try a different outlet

Disconnect External Devices
Connected devices can sometimes interfere with your TV's startup:
- 1.Unplug all HDMI cables, USB devices, and other accessories
- 2.Click to expand
- 3.Try turning on the TV with nothing connected
- 4.If it works, reconnect devices one at a time to identify the problem device

Test Power Sources
Power strips and surge protectors can fail over time:
- Plug the TV directly into a wall outlet, bypassing any power strips
- Test multiple outlets to ensure consistent power delivery
- Check that surge protectors haven't tripped their safety mechanisms

Reset Your TV
If basic troubleshooting doesn't work, try a reset:
- 1.Press and hold the power button on your remote for 5-10 seconds
- 2.Unplug the TV for at least one minute
- 3.Plug it back in and wait for the Samsung logo to appear

Check HDMI Connections
Faulty HDMI connections can prevent your TV from displaying properly:
- Ensure HDMI cables are firmly connected to the correct ports
- Look for physical damage like kinks or breaks in cables
- Try different HDMI ports on your TV
- Test with a different HDMI cable if possible
Factory Reset as Last Resort
If nothing else works, a factory reset restores your TV to original settings:
- 1.Press the Home or Settings button on your remote
- 2.Navigate to Settings > General > Reset
- 3.Confirm the reset and wait for the TV to restart

This will erase all your custom settings and connected devices, but it often resolves persistent power issues.
When to Seek Professional Help
If you've tried all these steps and your Samsung TV still won't turn on, you may be dealing with:
- Power supply board failure - Common in older Samsung TVs
- Capacitor issues - Electrolytic capacitors can fail over time
- Main board problems - Requires component-level repair
In these cases, contact Samsung support or a qualified repair technician. Many power supply issues are repairable without replacing the entire TV.
