Wondering why Sharp TV red light blinking? Then, stay invested throughout this guide!
It’s common sense that the blinking red light does not indicate something good on any device, hence it’s no different for the Sharp TV.
Let’s unwrap the meaning of the blinking red light!
The blinking red light on your Sharp TV indicates some sort of insufficiency which could involve power-related issues as well as software blunders.
In addition, when the signal is too bad or the remote control is faulty, the red light on your Sharp TV will be blinking.
Sharp TV Won’t Turn On Red Light Blinks – Why?
In case the Sharp TV won’t turn on, we can immediately assume that the device is experiencing issues on the hardware side of things.
This involves the power supply (equipment and outlet), as well as the hardware components such as the T-Con board, main board, and TV backlight.
Here are the reasons why the Sharp TV’s red light is blinking:
- Sharp TV power insufficiency.
- Electrical outlet malfunction.
- Faulty TV power equipment.
- The Sharp TV is overheating.
- Remote control interference.
- Third-party device bad signal.
- Defective hardware components.
Note: The blinking red light indicates that the device is receiving power!
Top 9 Ways To Fix The Sharp TV Red Light Blinking Issue!
Soft-Reset The Sharp TV
When the Sharp TV won’t turn on or the red light is blinking (or both), the typical first step is to turn off the television to achieve a power cycle.
This method will discharge your device and hopefully resolve any power complications.
Follow the steps below to soft-reset your Sharp TV in easy steps:
- Using the remote, turn off the Sharp TV.
- Unplug the power cable on the booth sides.
- Wait for at least 60 seconds.
- Reconnect the Sharp TV’s power.
- Press the Power button on the remote.
If your television won’t turn on, try pressing the physical power button located on the TV panel (typically on the bottom right).
Some Sharp TV models don’t have such a button so check the user manual for reference!
Inspect Power Equipment
When the Sharp TV red light on but won’t turn on, perhaps the culprit is in the power equipment.
The power equipment of your Sharp TV consists of a power cable + adapter and a power supply board (port), which converts the AC into the required DC voltage.
Without going any more technical we can check for the obvious:
- Inspect the electrical outlet or power strip!
- Check for burned connectors or melted plastic.
- Take a close look at the power adapter.
- Ensure that the power cable is not twisted.
- Connect the power cable tightly on both sides.
- Press the power button to turn on your Sharp TV.
Tip: Test whether the currently used outlet is supplying power to other devices!
Switch to a Different Outlet
When the red light on our Sharp TV doesn’t stop blinking, the next step is to change the location of the TV or carry an electrical extender from another outlet.
If possible, connect your TV to an outlet, which is in a different room, hence on a different fuse of your main AC circuit.
Quick Fact: The safest way is to plug your Sharp TV directly into a standalone power outlet.
In addition, it’s essential to plug your TV directly, even if you’re using a power strip since any third-party connectors such as smart plugs, can impact the power.
Try to recall a recent power outage, which might have impacted your TV (if it was connected) or the currently used power outlet.
In case of damage after a power outage, check your warranty and try to claim a free professional inspection.
Power Cycle The Remote!
It’s never excluded that the TV remote is malfunctioning, which if sending false signals to the TV, might develop weird television behavior.
For example, when a button on the remote is pressed, the red light on the TV blinks as an indication of successful control.
To check whether the blinking red light on the Sharp TV is from the remote, eject the batteries for a few minutes!
How To Power Cycle Sharp TV Remote?
- Open the battery compartment.
- Eject the AA or AAA batteries.
- Press all buttons on the remote!
- Insert the batteries in the remote.
In case the reason for the blinking red light on the Sharp TV was remote, after the power circulation the problem should be gone. If not, keep reading!
Disconnect Video Sources
The reason why your Sharp TV screen is black and the red light is blinking could be due to a playback or input video that is not working well.
The smart Sharp TVs, might blink in red when they are attempting to broadcast content from an app or through satellite.
Simply disconnect all devices from your Sharp TV, such as:
- Consoles & third-party TV controllers
- Computers, laptops, and smartphones
- Headphones, soundbars, and subwoofers
- DVR, DVD, or RCA Consoles and games
When everything is disconnected from the Sharp TV, try to turn on the device and check whether the red light will continue to blink.
Decrease TV Overheating
Even if rarely, any TV might start to overheat, and when this happens, the television turns off automatically as a secure mechanism.
This might make the red light on your Sharp TV blink and prevent the machine from turning on until it cools down.
Quick Tip: Turn off and wait for 5 minutes for the Sharp TV to cool down!
In addition, there are quite a few steps to decrease the TVs temperature:
- Ventilate the room with the Sharp TV.
- Open the windows to let in the fresh air.
- Remove heat conductors near the TV.
- Close ALL apps and tasks on the TV.
- Lower the content streaming resolution!
- Clear the ventilation openings on the panel.
Info: Overheating mainly happens during the hot summer seasons and during this time we recommend following the above steps to keep the temps low.
Try The “Long Unplug” Method!
Sometimes shortly after a power outage the electricity in our AC line might fluctuate for a while so during this time we shouldn’t use our devices.
We can quickly determine this by turning on a light and observing whether the light will change brightness and flicker.
- Simply, unplug the Sharp TV from the power for at least 30 minutes!
When you come back later and connect the TV to the power, the red light might no longer blink and you’ll be able to turn on the device.
In case the red light is continuously blinking, test whether the other TVs in your home function properly.
- Factory Reset Sharp TV
In case the red light on your Sharp TV is blinking but the TV is turning on and you’ve got access to the menus, we recommend the Factory Reset.
This process will erase all content, apps, and settings from the TV but will surely boost the performance and provide a fresh start.
Here’s how to factory reset your Sharp TV in easy steps:
- Plug in the power cable of your Sharp TV.
- Turn on the TV using the remote’s Power button.
- Press the Channel Down + Input buttons.
- On the pop-up screen, select Service Mode.
- Highlight and select the Factory Reset option.
The reset might take up to 30 minutes but remain patient and check whether the red light is still blinking when the process is over.
Understand Electrical Components
By now, we’re left with only assumptions but we’ve dug deeper to discover the components that might make the Sharp TV light blink in red.
When any of the below-listed TV components burs or go faulty after a power outage, the Sharp TV won’t be able to turn on and blink in red!
Here are the components that will surely prevent the Sharp TV from turning on:
- Faulty TV backlight
- Defective LED strip

Sadly, the replacement of these components is not possible at home and does require tools and attention.
We strongly recommend checking your warranty and if expired, taking the Sharp TV to a local professional for servicing.

Those include the power equipment, outlet, and TV port as well as connected third-party devices and voice sources.
