How to Fix Black Screen on Sharp TV
Follow the fixes in the given order one after the other and check if any of them have solved the issue.
Check the Sharp TV Remote
If your Sharp TV indicates a power supply but doesn’t turn on when you use the remote, then try turning it on using the physical buttons on the TV. If your TV did turn on, then the problem is with your TV remote. Change the batteries if the old ones have drained completely. Replace the remote if the buttons or the hardware have become faulty.
Check the HDMI Cables
On the other hand, ensure all the externally connected cables on your Sharp TV are working properly. If any of them are faulty, change them. If you want, try connecting the cable to a different HDMI port than your usual one and see if the problem has been resolved.
Change the Sharp TV Input
If you see a black screen on the Sharp TV when using the HDMI-connected device, don’t worry. This happens if you forget to switch the source on the Sharp TV. After changing the input, check whether you can able to watch the content from the connected source. If you still see a black screen, try the next solution.
Try Another Power Outlet
Sometimes, the black screen issue on Sharp TV happens due to improper power supply. In that case, your Sharp TV will not turn on properly even when plugged into a power socket. Connect your Sharp TV to another power outlet and check if it works properly. If the power outlet has no power supply issues, you won’t get the black screen problem on your TV.
Use Surge Protectors
In some cases, the Sharp TV screen may turn black due to an unexpected voltage spike. This can happen due to fluctuating voltage in the socket, lightning strikes, etc. To fix this issue, you can use a surge protector, which will absorb excess voltage and prevent your Sharp TV from hardware malfunction. Using a surge protector will also improve the TV’s average lifespan and protect it from black screen issues.
Power Cycle the Sharp TV

You might have knowingly or unknowingly put your Sharp TV on Standby Mode. When on standby, the Sharp television screen will go all black. You can wake the Sharp TV from this mode by pressing the Power key on your remote control or directly on the TV.

If your Sharp television screen turns black between shows, it could be a software bug or glitch. In such cases, you can update your Sharp TV software to the latest available software to eliminate the bug causing it.
As said earlier, it may be because of a bug in a specific app that you are using. To be on the safer side, ensure you update the apps on your Sharp TV as well. Always remember to keep your smart TV and apps up to date to avoid such troubles.
