If your Sharp television keeps shutting off, you may need to restart it. To do this, turn off the Sharp TV, unplug it from the wall outlet, and then plug it back in. Ensure that all the other devices are turned off, as well. This will reset the TV and should provide you with a working picture.
Black screen on Sharp tv
If you are having a black screen issue with your Sharp TV, you should first check your HDMI and power cables. If any wires are damaged or loose, replace them with a new one. If the cable is not damaged, the next step is to try to re-plug the Sharp TV.
Voltage fluctuations can also cause a black screen on Sharp television or even cause it to freeze. When this happens, you need to unplug the power cord for 60 seconds and then plug it back in. If this does not fix the problem, you can try to restart your Sharp TV. Pressing the power button for thirty seconds can sometimes resolve a black screen problem.
Another method for resetting a Sharp TV is to power cycle it. If you remove any external USB devices, this process can fix the black screen issue. After power cycling your Sharp TV, it will be ready to use again.
Inverter/lamp failure
The red standby light comes on but then goes off. When you push the power button, it seems like the screen is trying to turn on, but after about a second or two, it goes back to red. If the light keeps flashing, the problem is likely with the inverter/lamp.
In most cases, replacing the lamp will fix the problem. But in some cases, the inverter needs to be replaced. To check if your inverter needs replacing, check the voltage first. Make sure that the voltage is regulated correctly. If it is not, you may need to replace the inverter.
You should check the inverter board when your Sharp TV inverter/lamp fails. It may look black, and you need to clean it with a switch cleaner spray. If the inverter is good, you can use a thin layer of solder to cover the 18 connections. Then, your Sharp TV should be working again.
Power outlet
If your Sharp TV won’t power on, the most likely culprit is a damaged power outlet. You can try another outlet to see if that works, but if that doesn’t work, you may need to replace the power outlet or power source. In some cases, power outages can result in a blown a fuse, which a technician can fix.
Another problem that could cause your Sharp TV not to turn on is a dead battery. The battery may be dead if you’ve changed batteries and the television won’t turn on. Fortunately, this problem is easy to troubleshoot. Try unplugging the TV and reseating the power cord. It’s essential to make sure the cord is seated correctly and tightly to make sure power is reaching the television. If this fails, you may need to reset the Sharp TV.
Another common problem with power outlets is a lack of voltage. This problem may occur after a power outage, and the solution is to wait for the electricity to return to normal before trying again. If the problem persists, you can try switching to a different outlet, but wait until the power is restored before plugging the television back in.
Remote control
If your Sharp remote control is not working correctly, it’s time to contact the company’s support line. They can help you troubleshoot the issue and send you a replacement remote. You can also try resetting the remote control, which will often fix the problem. Before you call, you need to ensure that all of your Sharp TV’s software is up to date.
If the remote doesn’t respond at all, check the batteries. In many cases, a drained battery is the cause of remote control malfunctions. A faulty battery can prevent the remote from pairing with your Sharp TV. To test the remote control, unplug it and push the power button. If the remote still doesn’t respond, try pushing every button on the remote.
Another way to test the remote is to turn on the Sharp TV. First, you need to unplug the Sharp TV. Then, press the channel down and volume down buttons simultaneously. You should see a blue box in the upper left corner. Pressing the TV and display buttons simultaneously should bring up the service menu. Once there, select the first code in the programming list. The indicator light should stop blinking once you enter the correct code.
