Knowing how to troubleshoot a Sharp TV can help resolve a number of issues; saving you a lot of money in the process. While the actual steps to follow can vary and would depend on the model you own, there are some troubleshooting instructions that will work for multiple Sharp TVs. Read on to learn of the troubleshooting steps to follow to resolve some of the most common issues with these TVs.
How Do You Reset a Sharp TV?
While resetting signs you out of any apps on a smart TV and uninstalls any additional apps you have installed, it can often fix software-based issues that have developed. To reset a Sharp TV:
- Go to “Settings” menu using your Sharp remote.
- Then select “System” followed by “Factory Reset”.
- Press the “Play” or “OK” button three times to engage the reset process.
If you own a Sharp Aquos LC-52D64U LCD TV, there are two methods you can facilitate a factory reset: on-screen and using the hardware directly. Try these steps for on-screen menu reset:
- Start up the TV and press the “Menu” button on your remote control.
- Using the left and right arrow keys, navigate through the menu options until you find the “Setup” sub-menu.
- Select “Reset” and press the “Enter” button. If you have an access code (Secret Number) for parental controls, enter it using the remote control’s number pad and press “Enter” again.
- Highlight “Yes” using the left or right arrow key and press “Enter”. Select “Yes” again when prompted that the TV will restart and press “Enter”’.
- The TV will then display “Now Initializing” and the power will shut off. The TV will turn back on automatically, restored to factory defaults.
For a hard reset:
- Unplug your TV.
- Press and hold the “Channel Down” and input” buttons on the panel.
- Plug the TV back while holding down these buttons. Seek assistance for this step if you have to.
- Keep holding the buttons until the TV powers back on. If it doesn’t work, unplug the TV and try again.
- Use the remote to navigate the “Service Mode” menu and select “Factory Reset” from the menu. Click “Enter” and the TV will start initializing and shut down. It will then power back on, set to factory defaults.

- Plug the TV directly into the wall to rule out a bad power strip.
- Turn the TV back on and check the light.

Why Does My Sharp TV Keep Flashing OPC?
Sharp TV systems use several lights to indicate activity and potential errors. Any blinking activity on the TV OPC (Optical Picture Control) light most likely indicates an error. Problems can arise from hardware issues or the firmware installed on the TV.
If the TV doesn’t turn, the power lights are blinking or other issues arise while the Sharp TV OPC light is blinking, try to determine if the problem is hardware or firmware related. Feel the TV set for excessive heat. Excessive heat can indicate a faulty fan or another piece of hardware that is making the TV run without displaying the screen. If your TV is not overheating or making irregular noises, it may be a problem related to firmware or updates.
