If your Sharp TV’s power light is flashing and there’s no display and you want to know why, you’ve come to the right place.
When the power light on your Sharp TV flickers, but there is no picture, it can be an extremely unpleasant experience. When the power light or the OPC (Optical Picture Control) light flashes rapidly, it indicates a malfunction and sometimes this can lead to Sharp TV turning on, then off immediately.
You should not be alarmed since there are measures you can take to troubleshoot and perhaps resolve this issue. The problem could have been caused by a number of different circumstances. In this piece, we will walk you through a step-by-step approach to repairing your Sharp TV when you are experiencing issues such as a flashing power light and no display.
Why are my Sharp TV OPC and power light flashing (no picture)
Short answer: Your Sharp TV’s OPC and power lights are flashing and there is no picture due to Power Supply Issues, Overheating, Backlight Issues, Main Board Problems, or Loose Connections.
Reason 1 – Power Supply Issues
A television’s ability to operate is ensured by its power source. When there is an issue with the power source, it is possible for the OPC and power lights to flicker. It’s possible that this is the result of a blown fuse, a damaged capacitor, or some other problem.
Reason 2 – Overheating
It is possible for Sharp televisions to overheat if they are positioned in an area that has inadequate ventilation or if the air vents become blocked with dust. If the temperature gets too high, the TV can turn off, and the OPC and power lights might start flashing.
Reason 3 – Backlight Issues
The component known as the backlight is the part of the TV that is responsible for providing illumination to the screen as well as brightness. It is possible for the OPC and power lights to flicker as a result of damage to the backlight or improper operation of the backlight.
Reason 4 – Main Board Problems
The primary circuit board of the television is the component that controls all of the operational aspects of the device, including the picture and the sound. If there is a problem with the main board, it may cause the OPC light and the power light to flash. It’s possible that a faulty component or an issue with the program is to blame for this.
Reason 5 – Loose Connections
The blinking of the OPC and power lights may also be caused by connections between the TV’s components that are not securely fastened. It’s possible that this is due to a disconnected cable or a broken connector.
How to Fix Sharp TV power light blinking no picture
Method 1 – Check the power supply
When the power light on your Sharp TV begins to blink, the first thing you should do is inspect the power supply. Check to see that the TV is correctly plugged in and that the outlet in question is operational. You might also try switching the outlet that the TV is plugged into if that doesn’t work.
When troubleshooting any power-related difficulties with your television, including issues with the on-screen display (OPC) and flashing power lights, one of the most critical first you can do is to verify that your television is receiving the correct voltage.
When checking the voltage of the outlet, you can make use of either a multimeter or a voltage tester. If the voltage is either too low or too high, this may point to a problem with the board that controls the power supply.
Method 2 – Examine the Power Cord
It is very crucial to check for a damaged power cord as one of the potential causes if you are having an issue with your Sharp television in which the OPC and power lights are blinking, but there is no picture being displayed on the screen.
Your TV may have a range of problems as a result of a damaged power cord, including problems with the on-screen menu and the power lights flashing.
Be careful to inspect the full length of the cord, including the ends where it connects to the TV and the power outlet, to ensure that it is functioning properly. If you have found that the power cable has been damaged in any way, it is imperative that you get a new one.
Method 3 – Ensure that the TV is not too hot
When you are confronted with a scenario in which the OPC and power lights on your Sharp TV are flashing, but there is no picture, there is a possibility that your TV is overheating.
Make sure there is sufficient room around your television for air to circulate by checking this area. Check to see that the vents on the TV itself are not being obstructed by any objects. It is absolutely necessary to have adequate airflow in order to avoid overheating. Your TV’s vents and the other components found inside it are susceptible to collecting dust over time.
Method 4 – Power cycle the TV
Restarting your Sharp television is an efficient troubleshooting procedure that can help resolve a variety of difficulties, including the one in which the OPC light and the power light are flashing, but there is no picture on the screen.
The TV’s internal circuitry can be reset by cycling the power supply, which also helps cure any transient faults or software problems that may have occurred. Before moving on to more complex ways of troubleshooting, it is important to make an effort to solve the problem using this step first because it is both easy and effective.
Method 5 – Identify and Fix Any HDMI Issues
When you are confronted with a scenario in which the OPC and power lights on your Sharp TV are flashing, but there is no picture, there is a possibility that HDMI difficulties are to blame. Make sure that each of the HDMI cables that are connected to your Sharp TV has a strong connection.
Check the ports on the TV as well as the ports on any connected devices, such as a cable or satellite box, game console, or media player. This will ensure that the HDMI cables are working properly on both ends. It’s recommended to unplug and reconnect each HDMI cable individually to check for a stable connection.
If your Sharp television has more than one HDMI port, you can experiment by connecting the HDMI cable to one of the other ports. This assists in determining whether the problem is limited to a single HDMI port or not.
Method 6 – Update the TV firmware
By updating the firmware on your Sharp TV, you can potentially fix specific problems, as well as improve the general performance of your television and make it more compatible with other devices.
It is essential to take into consideration that the procedures for updating the firmware of your Sharp TV may be different based on the particular model and software version of the device.
Before attempting to update the firmware on your TV, you should always check the user manual or refer to the thorough instructions that Sharp has given for your specific model.
Method 7 – Check the TV main board/power board for any issues and call any TV technician.
If you have already tried the troubleshooting methods that were described before, but the OPC and power lights on your Sharp TV continue to flash even if there is no picture on the screen, it is probable that there is a problem with either the main board or the power board of the TV.
Check the main board and power board visually for any physical damage, such as burn marks, bulging capacitors, or other indications of overheating. To make sure the power board is supplying the right quantity of power, you can test the voltage coming from it with a multimeter. The power board has likely failed and has to be changed if the voltage is outside the expected range.
At this point, it is recommended that you get in touch with Sharp TV’s customer service or speak with a qualified TV repair specialist for assistance.
They are equipped with the knowledge and instruments necessary to diagnose and repair any problems with the TV’s hardware that you may be experiencing. Please provide a description of the symptoms, as well as the steps you have taken up to this point, to aid the physician in making a diagnosis.
Method 8 – Hard reset the TV
It may be necessary to perform a hard reset on your Sharp television in order to repair certain issues, such as those in which the OPC and power lights are flashing, but there is no visual.
A hard reset can be helpful in clearing temporary faults or issues that may be the cause of the OPC and power lights flashing without any picture being displayed on the screen. Because doing so restores the TV to the settings it had when it was first manufactured, it is crucial to keep in mind that any individualized settings or configurations will be erased in the process.
Performing a factory reset on your Sharp television is simple, and the instructions are as follows:
- Step 1– Make sure the power wire for your Sharp TV is plugged in.
- Step 2– Press the Power button on the remote control which will turn on the television.
- Step 3- Make sure that the Channel Down and Input buttons are both pressed.
- Step 4- Choose Service Mode from the menu that appears on the pop-up screen.
