Samsung Rear Projection TV’s LED lights are Blinking; What Does It Mean?

LED indicators on Samsung TVs let you know how they are currently functioning. For example, an indicator light may show the TV is working normally or display that the set is malfunctioning due to internal errors such as overheating, a blown lamp bulb, or other issues.

Lamp Light

If the light from the lamp is flickering, it means that the bulb inside the lamp is heating up. It may take the bulb about fifteen seconds to be warm and show a picture even when it is flashing simultaneously. If, after 15 seconds, there is still no picture displayed, look for other blinking indicators on your TV.

Auto-Timer Light

A light on the auto-timer is illuminated before the auto-timer is activated. A predetermined time can be set for the auto-timer to turn your TV off. You can cancel the auto-timer using your remote. Even if you stop the auto-timer, the TV will remain on.

Samsung DLP 3 Blinking Lights: Ways To Fix 

The Samsung DLP TV does not turn on, or the power lights blink for a long time. The TV may have a faulty power source resulting from a broken HDMI connection. To fix the problem, let’s look at how we can troubleshoot it.

Samsung DLP 3 Blinking Lights: Ways To Fix

1. Power Supply

If you discover a problem with your TV, your first step should be to check the power supply. Firstly, an inefficient and inappropriate electric current may have damaged the TV’s power supply. As a result, the TV won’t work correctly. However, it is possible that one of the components, either the capacitors or transistors, has failed. Therefore, we recommend you examine these components; if they have melted down, you should simply replace them with new ones.

Regarding the power supply, the power cords are also something to consider. Consequently, we recommend that you inspect the power cable and remove it from use if it appears to be damaged or frayed. In addition, you should connect the power cord of your Samsung TV to a different socket to check if the power socket is working correctly. After switching the power socket, if the TV continues to flicker, the problem is with the socket.

2. Launch Configurations

If your Samsung DLP TV cannot turn on or begin the startup process, there is a reasonable probability that the launch settings on the TV are right. These configurations are to thank for the decreased time required for the TV to start up, and they also save information if the TV is turned off. Therefore, we strongly advise you to update the launch settings you have set up using the official Samsung website.


There is a possibility that the Samsung DLP TV will continue to flash if the HDMI cable is damaged or does not function as it should. If you’ve been using gaming consoles with Samsung TVs, there’s a good chance you forgot to turn off the HDMI source. We suggest replacing the HDMI cable to resolve this problem, likely resolving the blinking issue.


4. Surge Protectors

For optimal performance, your Samsung TV requires a direct power source. Similarly, if you power a TV using surge protectors, you will experience problems with the TV’s power light blinking. 

Based on this information, you should remove the surge protector and try again. Consider replacing the old surge protector while you are at it and streamlining the power connection.

If you follow the steps above, you should be able to fix the issue with the blinking light on your Samsung DLP TV.

5. Capacitors

If your capacitors are not working the way they should, they may present no outward signs. However, there is a simple test for proper voltage; use a multimeter to check the voltage and compare it with the labeled voltage of your devices. An incorrect voltage reading on a multimeter indicates defective components in your device. Samsung TVs may not turn on if one or more of the capacitors on their board are damaged. The TV will need to be disassembled to access these components.

The bulb or the ballast does not cause this issue; rather, it may be caused by a combination of those components or the light engine itself. If it’s the light engine, throw everything out and start over. However, if you want to avoid wasting any more money, you should have it checked out by a technician.

Ensure your brand-new bulb’s connector is thoroughly inspected before replacing it. Ensure that the interlock switch on the bulb cover is engaged if everything appears in order.

Why is my Samsung TV blinking and not turning on?

A faulty power supply may cause your Samsung TV not to turn on even though the red light is flashing or blinking. In certain instances, the TV may have experienced a power supply failure due to excessive electric current flowing through it. It’s possible that this caused damage to the power supply or individual components, such as capacitors, transistors, etc. There is also the possibility that the HDMI port has a technical issue. Alternatively, the TV’s launch configurations may have become corrupted, causing it to have this problem when it tries to start.

What does it mean when the red light on your TV is blinking?

Three main types of issues can cause Samsung TVs with blinking red power buttons:

1. Your TV has become unresponsive because of a faulty software update, and to fix it, you will need to do a power cycle, sometimes known as a “soft reset.”
2. There is a problem with the connection or the source. For example, an HDMI hiccup or improper source selection might occasionally be to fault.
3. The electric current flowing incorrectly may result from a malfunctioning power outlet or surge protector, faulty LED backlights, or a power board with bloated capacitors. 

If the red blinking light is on, you must factory reset your Samsung TV. Please turn off your TV and wait precisely one minute after turning it off.  The TV should be unplugged, and hold the power button for half a minute. After a minute and a half has passed, re-plug your Samsung TV, and it should start working.
