Fix Sharp TV Flashing Red Light

It is frustrating when we sit comfortably to watch TV and find that there is a problem with it, especially when we are in the mood to watch a favorite show. If you are also facing the same issue of a Sharp TV blinking red light, read the article till the end and apply the below-mentioned methods one by one to see which one works for you, and let us know in the comments.

Check the Power Supply

Since the TV can’t operate with the power supply, a failing power supply may cause your Sharp TV to flash a red light. This could be due to a surge or an unstable power source. Hence, examine if the socket has sturdy electricity or not. If it has, but you still have the same problem, move forward to the next step.

Change the Power Cord

If your TV’s power cord is damaged, it may flash a red light. The power cord gets damaged due to several reasons, including the high voltage, faulty wiring, or others. If that’s the case, you need to change the power cord, as it should fix the issue. Even after replacing the power cord, if you still face the same problem, move on to the next fix.

Power Cycle the TV

Another simple thing you need to try is to power cycle your Sharp TV. In most cases, this will fix the blinking red light problem. To do this, just unplug your TV’s cord from the power outlet and wait for about 1-2 minutes. After that, plug the cord again into the outlet and check if the issue is resolved or not. Most probably, it should be gone. If not, move forward with the next fix.

Connect the TV to a Different Outlet

The next thing you can try is to connect the Sharp TV to a different power socket, as there might be chances that the wall outlet is damaged.

You can also try connecting another device to the suspected faulty outlet and see whether it’s working fine or not. If another device works fine, it means the issue is not with the outlet. On the other hand, if the issue does not work, the outlet is the cause of the problem.

Force Restart the Sharp TV

Another thing you can try to resolve the issue is to force restart your Sharp TV. This method works only for Sharp TV models that have physical buttons. Here’s how you can do this:

Step 1: Press the Power, Volume Down, and Channel Up buttons at once on the TV.

Step 2: If you hear a clicking sound, it means the force restart works.

Wait for a minute and see if the TV turns on normally without a red light or not. If not, move on to the next troubleshooting fix.

Examine the HDMI Cable and Port

If the HDMI cable is loosely connected to the TV or if there is any damage to it, this can be the reason behind the red light flashing issue.

First, check if the HDMI cable is properly inserted into the port, and if it is, try to reconnect them. Inspect the HDMI cable for any cuts and bends, and if you find any damage in the cable, connect a new HDMI cable, and the issue should be fixed. Moreover, try to plug the HDMI cable into a different port, as the issue might be with the HDMI port.

Power Cycle the Remote

Some Reddit users have reported that power cycling the remote helps them fix the issue. This is possible because the remote may be malfunctioning and sending false signals to the TV, which causes issues like a flashing red light. Here’s how you can power cycle the Sharp TV remote.

Step 1: Remove the batteries from the remote control.

Step 2: Press and hold the Power button for about 30-40 seconds.

Step 3: Tap every button on the remote one by one.

Step 4: Finally, insert the batteries again into the remote.

Let TV Cool Down

Overheating may also be the reason behind the flashing red light issue. If the TV is placed in a closed area with low ventilation, it can overheat.

In this case, just turn off your Sharp TV and wait for a few minutes until the TV cools down. Next, turn it on and check if your issue is fixed or not. If the issue is resolved, remember to always keep the TV in a place with enough ventilation to release the heat.

Contact Sharp Customer Support

If none of the methods listed in the article help you fix the issue, you need to contact the Sharp support team, as the issue might be due to a faulty motherboard, mainboard, or other hardware. If your Sharp TV is under warranty, you can get the repair for free.

Wrapping Up

So, these are the ways through which you can fix the Sharp TV flashing red light issue. While many websites suggest updating the TV firmware, factory resetting the TV, or others, we have not listed them since they are baseless as the TV is not powering on.
