Fix Black Screen On Sharp Roku TV:

Modern Smart Televisions benefit from black displays. When your Sharp Roku TV turns black, it typically means something more ominous than a simple software error.

My experience with the Sharp Roku TV has been mostly positive. The image is excellent, the audio is good, and the Home screen is simple. As usual, the built-in Roku features provided excellent entertainment.

One day, I discovered my Sharp Roku TV screen had gone black. The explanation could have been more precise initially, but I ultimately devised a solution. This is how I corrected it:

Sharp Roku TV's blank screen implies defective power cords or damaged PCBs.

Here are my suggestions for resolving the black screen issue on your Sharp Roku TV:

Restart or Power Cycle the Television

Try rebooting your smartphone as soon as the screen becomes black and unresponsive.

  • The simplest way is to conduct a power cycle test on the device. Disconnect the power cord and re-plug it after a few seconds.
  • A power cycle refreshes the system and removes any problems causing the black displays.
  • It will also help to improve the system's efficiency and speed. Try this step, especially if your Roku TV has lately been sluggish.

Also, try restarting the TV with the remote. To restart the TV without plugging out the power cord, press these buttons on your Sharp Roku TV Remote in succession.

  1. Five times, press the Home button.
  2. Press the Up button once, then the Rewind button twice.
  3. Finally, twice, push the Fast Forward button.

The restart procedure takes about 30 seconds to a minute. If you were unable to restart the television, hit the buttons again. Check to see whether you were successful in resolving the issue. If the problem persists, see the following advice below.

Analyse the Sharp Roku TV's Power Cable

A shaky Power cord might create serious problems, such as the current black screen. Always ensure that you have a solid connection not just to the TV but also to the outlet.

  • An incorrect connection might result in TV banding. Banding issues create a gradual shift in the hues of pictures that correspond to a specific colour.
  • The dark screen is an extreme example of such a problem. If you have an afflicted screen, you may need to recalibrate it to restore it to factory settings.

Examine the TV's Dimming Settings

Select Sharp Roku TV models with varied screen sizes, including an auto-dimming feature that changes the screen's brightness based on the time of day and the amount of light available.

  • The Optical Picture Control Technology (OPC) can sometimes be cumbersome, dimming the screen to pitch-black darkness.
  • To turn off the function, go to the TV's Settings menu and choose Advanced Settings. The OPC choice will be at the top. Restart the TV after switching the option to OFF.
  • Alternatively, eliminate any automated dimming settings by turning off the Auto-contact option inside the same Advanced settings menu.


Aside from the problems and treatments listed above, a damaged motherboard or PCB might cause your screen to go dark.

The T-CON board, which handles visual signal translation, is a well-known source of the problem. You need to picture if your T-CON board is fried.

You may change the board yourself. However, it can be not easy. For a better solution, consult a specialist or contact Roku or Sharp Customer Service.

Consider replacing the TV since fixing a dead backlight panel or boards may be time-consuming and, if not always, costly.

FAQ (Frequently Asked Questions)

Sharp Roku TVs Last How Long?

If not plagued by defective hardware faults, a Sharp Roku TV, like any other Smart TV, may survive between 7 and 10 years. And I must underline that this forecast would occur only under perfect conditions. Give it 5-7 years in real terms.

Do Black Displays on Roku TVs Result from Interference?

Interference might impair a Roku TV's connection and streaming capabilities. However, until the stream turns dark, the screen will not necessarily go black. So, to answer your question, interference cannot hinder your Roku TV's display capabilities.
