It can be frustrating when your Samsung TV suddenly displays a red blinking light and no picture. This blinking light is an error code that indicates there is a technical problem with the TV. In this article, we will explore the common causes and solutions for a Samsung TV that is blinking 5-6 times with no picture.
What Does 5-6 Red Blinks Mean?
When a Samsung TV blinks 5-6 times, this generally indicates there is a problem with the power supply or backlighting of the TV. Specifically, 5 blinks mean the TV has detected an issue with the backlights, while 6 blinks indicate a problem with the power supply voltage.
Some of the potential issues signified by 5-6 red blinking lights include:
- Faulty or deteriorating backlight LEDs
- Backlight driver failure
- Overvoltage or Undervoltage of the power supply
- Short circuit on the power supply board
- Failure of a chip or capacitor on the power board
So, in essence, the TV is alerting you that it is not receiving the expected electrical power to turn on and display a picture fully.
What to Check if Samsung TV Blinks 5-6 Times
Here are some steps to troubleshoot a Samsung TV that is blinking 5-6 times with no picture:
1. Power Cycle the Television
The first thing to try is unplugging the TV from the wall outlet for 60 seconds. This resets the TV and allows capacitors to discharge. Then plug it back in and press the power button. This power cycling can sometimes fix minor glitches that cause the red blinking light.
2. Inspect Connections
Ensure all connections on the back of the TV are secure, including the power cord, HDMI cables, and antenna/cable connections. Loose wires in the power plug or in-wall outlet can cause power issues that prevent the TV from powering on fully.
3. Try Different Outlets
Plug the TV power cord into a different electrical outlet, preferably on a different circuit. This determines whether the issue is with the TV or the outlet power supply itself.
4. Replace Power Supply
The internal power supply will likely fail if the blinking persists through these steps. This component provides the required voltages to components like the LED backlights. The power supply is integrated into the main board on some Samsung TVs. On others, it is a separate replaceable part. Consult your TV model’s service manual to determine the power supply location and order a replacement if needed.
5. Replace Main Board
If all power outputs are affected, a faulty main board may need replacement for TVs with integrated power supplies. The main board contains critical processing components and the power supply in one. Have an authorized Samsung TV repair technician determine if your main board needs replacement.
6. Replace Backlights
Failed LED backlights are a common cause of blinking Samsung TVs. Maintenance involves carefully removing the back panel to access the LED strips or bars that provide display backlighting. Have a repair technician determine if your backlights need replacement and follow their guidance to install new backlight components.
How to Fix Samsung TV Red Light Blinking 5 Times
If your Samsung TV blinks 5 times specifically, the issue likely points to backlight problems. Here are a few steps to fix a blinking red light 5 times on a Samsung TV:
- Locate the backlight LED strips inside the TV panel and check for any damaged or burnt-out LEDs. Replace any faulty individual LEDs on the strip.
- Check the backlight driver board that controls the LEDs and replace if faulty. The driver ensures balanced voltage and current to each backlight.
- Examine connections between backlight LED strips and the driver board. Reflow solder joints if any are cracked or detached.
- Update TV firmware. In some cases, a software bug can cause backlight blinking. Find firmware updates for your specific Samsung TV model.
- Replace the entire backlight LED strip or bars if individual LED fixes don’t resolve the blinking red light 5 times.
Fix Samsung TV Red Light Blinking 6 Times
When the TV blinks 6 times, the power supply is having an issue:
- Test voltages on the power supply board using a multimeter. Check outputs for shorts and replace any blown fuses.
- Replace faulty capacitors on the power supply. Bulging or leaking capacitors can cause power issues.
- Update firmware. Software bugs may also affect power supply functionality.
- Replace the complete power supply board if component-level fixes don’t stop the blinking.
- The main board may need a replacement for TVs with an integrated power supply on the main board.

Preventing Samsung TV Red Light Issues
To help avoid technical problems like a blinking red standby light in the future, here are some tips:
- Keep the TV away from moisture, extreme temperatures, and dust to prevent damage.
- Ensure the TV has proper ventilation to prevent overheating components.
- Use a surge protector to protect against power surges that can damage TV circuits.
- Keep TV firmware updated for optimal performance.
- Have a qualified technician perform preventative maintenance and TV servicing annually.
While a blinking red light may seem ominous, in most cases, the problem can be readily identified and fixed once the TV is opened up. Your Samsung TV can be restored to full working order with the right components replaced. Being aware of the potential issues indicated by 5-6 red blinks can help you take the proper steps to get your TV operational again.
