Fix: Sharp Roku TV Not Turning On (7 Ways)

Are you having trouble getting your Sharp Roku TV to power on?

It’s frustrating when you can’t watch the programs you’ve been meaning to, can’t see the news you need to know, and can’t spend quality time with the people with a movie.

In this article, we will help you figure out what’s going wrong and how to fix it by walking you through the causes and solutions discussed.

Why is my Sharp Roku TV not turning on

Short Answer: Your Sharp Roku TV might not turn on due to a defective power outlet, software or hardware issues, faulty cable connections or remote control, broken backlight, or a faulty HDMI port.

Sharp Roku TV

1. Defective power outlet

The television will not receive power, and therefore will not turn on, if the electrical socket is malfunctioning.

2. Software issues

Bugs or incompatibilities in the TV’s operating system are two common causes of software errors. The TV may not power on properly because of these problems.

3. Damaged cables

A malfunctioning power cord may prevent electricity from reaching the TV, which can therefore fail to come on. Damage to the power wire or faulty connections will prevent the TV from receiving power.

4. Issues with remote controller

If your TV’s remote control isn’t working or interacting with the set, you won’t be able to transmit the signal to turn it on.

5. Faulty HDMI port or cable

Problems with the HDMI connection or port may prohibit the TV from showing content or powering on. Disruptions in data transfer between the TV and peripherals might occur if either the HDMI port or cable is damaged.

6. Defective TV backlight

A television’s backlight provides the light for the display. If the TV’s backlight is broken, it could not power on or show an image. This is something that has to be fixed or replaced by an expert.

7. Hardware failures

The TV may not be working properly due to a hardware issue, such as a faulty power supply or internal components. Because of these faults, the TV may not turn on or could act strangely.

Fix: Sharp Roku TV won’t turn on

Method 1: Verify the Power Supply

If your Sharp Roku TV isn’t functioning, try connecting it into a different, known-good power outlet. You may also verify the functionality of the outlet by testing it with another appliance. In addition, the power cord should be inspected for any problems.

Method 2: Reset your remote

  • Step 1: Take out the batteries from the remote.
  • Step 2: Press all the buttons several times.
  • Step 3: Place the batteries back in the remote.
  • Step 4: Turn on your Smart TV using the remote.

Method 3: Change the Batteries of the Remote

Get rid of the old batteries and swap them out for new ones. Be careful to place the batteries in the right orientation, with the positive (+) and negative (-) ends aligned with the corresponding signs within the compartment. Reset the remote after you have replaced the batteries in it to make sure it works properly with the TV.

Method 4: Reboot the TV

  • Step 1: Remove the plug of your Sharp TV from the socket
  • Step 2: Wait for at least a minute
  • Step 3: Hold the power button on your TV for 30 seconds
  • Step 4: Put the TV plug back in the socket

Method 5: Force turn on your Sharp TV

If your Sharp TV won’t switch on and the logo on the front is flashing quickly and then slowly, you may need to turn it on forcibly. However, you have to use the TV itself, rather than the remote, for this.

  • Step 1: Press the volume down and channel up button simultaneously
  • Step 2: Power on your TV while holding those buttons.
  • Step 3: Wait till you hear a clicking sound from the TV

Method 6: Perform a factory reset on your Sharp TV

  • Step 1: Locate the reset button on your Sharp Roku TV

It’s often located behind or to the side of the screen, next to the TV’s HDMI input.

  • Step 2: Make sure your device is powered on.
  • Step 3: Press and hold the button for at least 10 seconds.
  • Step 4: Wait till it shuts down
  • Step 5: Keep holding it until it powers back on
  • Step 6: Leave the button

When the factory reset is complete, the TV will reboot twice and finally turn on.

Or you can also hard reset your Sharp TV in the following manner:

  • Step 1: Remove thhe plug of your Sharp TV from the socket
  • Step 2: Simultaneously press and hold the volume down and input button.
  • Step 3: Plug your Sharp TV back in while holding those buttons.
  • Step 4: Keep holding until your TV boots back up
  • Step 5: Try again if it doesn’t work
  • Step 6: Find your Sharp TV’s Service Mode menu.
  • Step 7: Select the Factory Reset option
  • Step 8: Use the Ch +/- to select an Input to Confirm

Method 7: Examine for Faulty Backlight

Even if your Sharp Roku TV is turned on, a broken backlight will prevent any image from displaying. If the red light is flashing on your TV, you will see nothing but a blank screen.

  • Step 1: Make sure your device is plugged in.
  • Step 2: Aim a flashlight towards the screen of your TV.

The only thing you should be able to see with the flashlight is the reflection if your TV’s backlight is operating properly. If, somehow, dim pictures appear on the screen when you directed the flashlight at the TV, the backlight is broken and you will have to consult a technician to get it replaced.
