How to Fix Sharp TV Blinking Red Light Issue

You can carry out these fixes in a chronological way to solve the Sharp TV blinking red light issue.

Check the Power Supply

Poor power supply is the most common reason for the red light blinking issue. The power source is the medium for the TV’s operating ability. Apart from the TV issue, you must check if the wall socket has a stable power supply without interruption.

Any power-related problems can cause the power lights on the TV to flicker, leaving the Sharp TV with a blinking red light indication. If the TV has enough power supply to run the TV, but you are still facing the red light issue, you can move to the next troubleshooting fix.

Change the Power Cord

Sometimes, the Sharp TV cord may be damaged by high-voltage surges, lightning strikes, faulty wiring, etc. During that time, the Sharp TV may blink a red light to indicate the issue. Contact a TV repair technician nearby and fix the faulty cord. After repairing, check if the flashing red light on your Sharp TV has stopped.

Force Restart the Sharp TV

If your Sharp TV is not powering up and the red light blinks 6 times, you can force restart the Sharp TV. This process works for Sharp TV models having physical buttons on the TV unit.

1. Press the Power, Volume Down, and Channel Up buttons simultaneously.

2. If the force restart on Sharp TV works, you can hear some clicking sound on your TV.

3. Your Sharp TV will turn on normally without a light blinking indication.

Connect the TV to a Different Power Socket

The next solution is to change your Sharp TV to a different power outlet. Even if the power supply is stable, there may be a chance of damage to the wall socket. So, connect your Sharp TV to a different outlet and check if the problem is resolved.

Alternatively, you can connect another device to the faulty power socket and check whether the problem is with your TV or the outlet. This will help you determine the root cause of the Sharp TV blinking red light issue.

Examine the HDMI Cables and Ports

Any fault in the HDMI cables or ports can cause the TV to blink with a red light repeatedly. In rare cases, we may not notice whether the cables are inserted properly into the Smart TV. If you find any damage to the HDMI cable or the cables connected loosely to your TV, this can raise a red light blinking issue. Below is a clear and elaborate note on the possible cause of the issue related to the HDMI cables.

• A faulty or damaged HDMI cable will turn on the Sharp TV but allow it to blink with a red light. Minor damage can also have a significant impact on the TV. So, it’s better to opt for a new HDMI cable to relieve this issue. Also, if you use an old HDMI cable, try a new one for better performance.
• Sometimes, the fault may be with your Sharp TV’s HDMI port. In this case, change the cable to a different TV HDMI port.
• If the HDMI cable is connected loosely to the TV’s port, remove it and re-plug the cable correctly into the suitable port.

Power Cycle your Sharp TV

If the power supply is stable and there is no problem with the power socket and the HDMI cable, it’s time to power cycle the TV. Doing so will clear internal glitches and temporary errors.

1. Turn off your Sharp Smart TV and remove the cord from the power socket.

2. Wait for about a minute to drain out the excess power.

3. Plug the TV cord back into a wall socket and power on the Sharp TV.

Finally, check if the Sharp TV still has a flashing red light. If so, try the next workaround.

Power Cycle the Remote

Like the TV, sometimes the remote may malfunction abnormally, sending false signals to the Sharp TV. These wrong signals cause the red light to blink, creating the Sharp TV blinking red light issue. You can power cycle the remote to fix this problem.

1. Open the battery compartment on the Sharp TV remote.

2. Remove the batteries from the remote and hold the Power button for 20-30 seconds.

3. Press every single button on the remote 4-5 times and insert the batteries into the remote.

That’s it. Your Sharp TV remote is done with the restart process. If the issue is with your remote, the red light should stop blinking. If it still blinks, the problem is with your Sharp TV.

Fix Overheating Issue

The Sharp Smart TV may overheat if placed in an area with inadequate ventilation. The lack of air ventilation increases the temperature and thus stimulates the TV to get overheated. If this happens, it may cause the TV to function abnormally and cause the Sharp TV’s power light to blink 2 times. Always keep the TV in a place with enough ventilation to release the heat.

Update the TV Firmware

Sometimes, the Sharp TV may blink with a red light because of outdated firmware. It’s worth keeping your Smart TV up to date to fix any other issues related to the Sharp TV. To rectify this, update the Sharp TV firmware manually to get a good result. Make sure you connect your Sharp Smart TV to WiFi to undergo the process.

Examine the Power Board Failure

The red light blinking issue may occur if your Sharp TV has faulty internal components. Any damage to the main board, capacitors, LED strip, or backlight can cause the red light to blink abruptly. The backlight is one of the major components that illuminate the picture on your Smart TV, so the red light will blink if it has become faulty. You can reach out to the professionals to repair it, as handling the electrical components will be a risky process.

Factory Reset the Sharp TV

If none of the listed solutions help to get out of the issue, you can factory reset the Sharp TV to its default settings. However, the resetting process will erase everything on your Sharp TV. Hence, you need to set up your Sharp TV from the beginning. Once the process is over, the red light blinking issue, temporary bugs, and minor issues will be cleared out.

Contact Sharp TV Customer Support

If the above-mentioned fixes don’t work out, don’t get fed up. We recommend you contact the Sharp support team. If your Sharp TV has a warranty, you can ask them to assign a certified technician to repair the faulty component at your doorstep. Alternatively, you can use any of these modes to contact Sharp TV customer support for assistance.
