Fixes to Resolve the Sharp TV Keeps Turning Off Issue
If you can’t find the exact reason why the Sharp Aquos TV keeps shutting off issue. You can try the below-mentioned fixes one by one to resolve the issue by yourself.
Check the Power Cables & Power Source
A faulty power supply will not turn on, which may cause an issue and lead to black screen problems on the Sharp TV. So, make sure to have a standard supply of current to your Smart TV.
Any damage to the power cables will also break the flow of the power supply and thus create a problem. In this case, it’s better to opt for a new cable for your Smart TV. Sometimes, in a hurry, you may loosely connect the power cables to the power socket of your Sharp TV. This resulted in the Sharp TV turning off issue.
To recover your TV from this problem, be sure to have a proper power cable and a sufficient power supply. If this reason couldn’t fix the issue, march forward toward the next fix.
Disconnect the TV from WIFI
If you have connected your Sharp TV to voice assistants like Google Home or Amazon Alexa, you may face this issue constantly. Since these smart devices support voice commands, when you try to control any of your smart home devices, your Sharp TV may accidentally turn off. So, you should be careful while commanding and controlling the smart devices in your home via voice commands.
Check for Overheating of Sharp TV
If you leave your Sharp TV on for a longer period, it will overheat, which can cause it to function abnormally and turn on and off at regular intervals. Also, overheating causes blockages in your Sharp Smart TV’s ventilation system.
To prevent this, leave your TV undisturbed for a certain period and then clean the dust & dirt particles accumulated on the internal components of your TV. By doing this, the problem should be solved on your Sharp TV.
Change the Signal Format of Sharp Smart TV
At times, changing the signal format on your Sharp TV can readily fix the Sharp TV’s issue of turning off. When I faced this issue on my TV, I tried changing the signal format and recovered from the issue permanently. So, follow the below steps to modify the settings on your Smart TV.
1. Switch on your Sharp Smart TV using a remote control or the remote app.
2. Navigate to the TV Settings.
3. Choose the Display Settings option and select the Signal Format.
4. The correct signal format for Sharp TV is 1080p. So, change the existing settings and choose the correct format again. Now, the problem will be fixed on your Sharp Smart TV. If not, move to the next troubleshooting method to fix the Sharp TV not turning on issue.
Turn Off HDMI CEC
The HDMI CEC allows a two-way connection between your Sharp TV and the connected HDMI devices. If you control the external media player with its remote, there may be a chance to turn off your Sharp TV. This is one of the primary causes of the Sharp TV screen flashing on and off. You need to disable the HDMI CEC on your Smart TV to prevent this issue.
Turn Off Sleep Timer
Another reason the Sharp TV turns off is that the sleep timer may be enabled on your Smart TV. Every Sharp Smart TV is furnished with a sleep timer feature that allows users to switch their TV on and off at certain periods. So, try to turn off the auto standby on Sharp TV to get rid of the issue.
To disable the feature, navigate to Settings → Energy Save → Power Management Setting → Auto Power Shut-Off and proceed with the prompts.
Update your TV Firmware
Sometimes, your Sharp TV may turn off frequently if running out of updates. If you have turned on the auto-update option on your TV, the TV will automatically update itself to the latest version once you connect your Sharp TV to the WIFI network. However, the auto-update option may not work sometimes and will leave you in trouble. So, it’s better to update the firmware on your Sharp TV manually.
At times, Sharp TV won’t connect to the internet connection. In those cases, you should connect the TV to a different home network or use a USB flash drive to update the TV software. You can also try using these alternative ways if your Smart TV is not connecting to the WIFI. Once done, check if the problem is solved on your Smart TV.
Check the Sharp TV Hardware
Another possibility that the Sharp TV keeps turning off is a damaged main board or any damage in the hardware components of your Smart TV. This is a serious issue which cannot be resolved at your home.
If you are not well-versed in the electrical components, you cannot handle a damaged main board, bad capacitors, and diffused fuse. So, it’s better to seek help from a technician to get your Sharp TV back from the issue.
Factory Reset Sharp TV
Have you tried out all the above-listed fixes and still couldn’t get your Sharp TV back from the issue? The last fix is to factory reset your Sharp TV to its initial settings. This will eventually fix any temporary glitch that is causing Sharp TV to keep turning off issue.
But remember! Once you are done with the reset process, you need to set up your Sharp TV from the beginning stage. Most probably, this fix will resolve the issue on your Smart TV, as factory resetting will clear the temporary issue and the internal glitches on your Sharp TV.
