Solutions to Fix the Sharp TV Not Turning on Issue
Whatever Sharp TV models you use, follow the below solutions to fix your Sharp TV that is not turning on.
Check the Power Supply
When your TV is not turning on, the first thing you should check is its power supply. Electricity is the lifeline of any electronic device. So, it is better to check the power supply is receiving constantly on the power socket. If not, unplug the power cord from the socket and plug it into a different socket that has a good power supply.
Now, check whether the TV is turning on. If your TV is not turning on, then there might be no electricity in your house. Check whether any other electrical appliances like the refrigerator or washing machine are running. If other electrical appliances are also not working, you need to wait until the electricity comes back. Also, your Sharp TV will not turn on if your home has a low-voltage power supply. So, you need to wait patiently until the proper flow of electricity comes to your home.
Inspect the Stabilizer or Surge Protector

If there is no issue with your home’s electricity or if the power socket is working properly, then the issue might be with the malfunctioned stabilizer or surge protector. So, if you have connected your TV with the surge protector or stabilizer, then you need to check whether it is running properly or not. If there is any issue with the stabilizer, it will not send the power supply to your TV from the power socket. So, unplug the power cord of your TV from the surge protector and connect it to the wall socket.
Check the Power Cable
If you have connected a damaged or loosened power cord to your TV, it will not receive a sufficient power supply to turn it on. So, unplug the power cord from the wall socket and inspect whether there is any tear or damage on the power cable. If there is any visible damage to the power cord, replace it with a new one. Also, check whether the power cord is plugged firmly into the port on your Sharp TV. While plugging a new power cord into your TV, make sure to connect the plug firmly to the port. Also, confirm that the power cord port on your TV is free from dust, dirt, and corrosion. If your TV is not turning on even after changing the power cables, move to the next step.
Check Your Sharp TV Remote and its Batteries
If your TV is not turning on but the standby light is glowing, then there is a possibility that the issue is with your TV remote. Due to the low or no power on your remote batteries, the remote will not send signals to turn on your TV. So, changing the batteries on your remote periodically is necessary to avoid this kind of issue.

Take your TV remote and remove its battery cover. Remove the old batteries from the compartment and clean them with a dry cloth without damaging the battery contact spring. Next, insert a fresh pair of batteries by properly looking at the positive and negative polarities. Also, you need to check whether any of the remote buttons are stuck due to dirt or dust. Clean the remote and release all the stuck buttons. In addition, you need to check whether the remote’s IR emitter is working properly. Once you have cleaned the remote, changed the batteries, and inspected the IR emitter, press the Power button to turn on your TV.
Power Cycle Your Sharp TV
Temporarily glitches on your TV are also one of the reasons why the Sharp TV is not turning on. So, perform a power cycle on your TV to clear all the temporary glitches and bugs. It will also clear the residual electricity that prevents your TV from turning on.
1. Make sure your TV is switched off and unplug its power cord from the power socket.
2. Press and hold the physical Power button on your TV for 15 seconds. This will clear all the remaining power from your TV’s capacitors.
3. Wait for 2 minutes. Plug the power cord back into the electrical socket, switch it on, and see if your TV turns on.
If your TV is not turning on even after a power cycle, move to the next fix.
Hardware Issues

If none of the above-mentioned fixes helps you to power your TV, there might be internal hardware issues, such as a backlight failure or a power board failure. If the standby light is glowing and it blinks whenever you press any buttons on the remote, there is a probability that the issue is due to backlight failure.
When the backlight is damaged, the TV exhibits a black screen, and you can hear only audio if any content plays on the TV. To confirm the backlight issue, turn on your TV, point the flashlight on your TV, and check if you can see any mild images on the TV. If you find any movement on your TV screen, you can confirm the issue is with the backlight.

On the other hand, if the standby mode is not glowing on your TV, there is a possibility of power board failure. The power board and backlight can be repaired only by professionals.
