Whether you’re at home or on the road, if your television doesn’t turn on, there’s a good chance that you’ll have to get out your tools and tackle some troubleshooting. The good news is, there are a few simple steps you can take to make sure that your TV works again.
Check if your TV is plugged into an extension cord
Using an extension cord to plug your television into may be tempting, but it’s not a wise decision. Extension cords are not designed to handle large amounts of current, and using them for long periods of time can be dangerous. In addition, the cable may get damaged, which can void your warranty.
The best way to make sure that your extension cord is in good working order is to check it occasionally. Make sure that the cord is free from burns, damage, and melted insulation. You should also be sure that the cord is plugged into a wall outlet securely. You may want to replace your extension cord if it looks as if it has been damaged.
You can also check the extension cord to see if it has any open connections. A loose connection can create imperfect flow of electric current, which can cause damage to your television.
In addition to checking the cord, you may want to consider buying a surge protector to help protect the television from voltage spikes. If you have a surge protector, be sure to use it correctly. If the surge protector is defective, it may not provide enough power for your television.
You may also want to consider using a heavier duty extension cord. Heavy duty extension cords have a special design that is designed to provide power to heavy duty appliances, such as TVs.
Check if your power outlet is working
Whether you are trying to turn on your TV or plug your device into an electrical outlet, it is important to make sure that it is receiving power. A dead outlet, or an outlet that is not receiving power, can be fixed quickly and easily.
There are several reasons why an outlet may not be receiving power. The first is that it may have a loose connection. A loose connection can cause electrical arcing and sparks. Also, a power surge protector may be the cause of the problem.
Using a multimeter or voltage tester, check to see if your outlet is getting power. You can also check the wiring on the outlet to see if it is in good condition. If the wiring is loose or damaged, you can fix the wire by replacing it.
When you are checking your outlet to see if it is receiving power, you should see a rounded half circle, also known as a ground slot. This slot is shorter than the other slots.
You should also be able to see a solid line and a wavy line if your outlet is doing the direct current function. A hot outlet means the wiring is damaged or faulty.
If your outlet is not receiving power, you may need to repair the outlet or the breaker. This can be done by a certified electrician. A certified electrician will provide a warranty for the work they do.
Check if your TV’s backlight is broken
Often, if you experience backlight failure on your TV, you will not be able to see any picture on the screen. If the screen is completely black, then you will have to replace your LCD (liquid-crystal display panel). This is usually more expensive than replacing the TV itself.
There are several causes of backlight failure on TVs. These include a bad LED driver board, backlight strip, high voltage inverter hardware, or a capacitor. Most of the time, these problems are caused by a defect or malfunction in the backlighting system. You should take your TV to an expert for a diagnosis and repairs.
A good rule of thumb when diagnosing a backlight problem is to first check for any voltage that is above 100 volts. If the voltage is below 100 volts, then the board is not supplying power properly. You may need to replace the power supply board.
Other causes of backlight failure include water damage, drop damage, or a defective component. If you can access the back of the TV, you will be able to see the backlight strip. These strips are usually recessed inside the TV frame and should be aligned properly.
Once you’ve accessed the back of the TV, you should carefully remove the LED panel. Carefully unscrew the back screws and pull the panel out of the chassis. If the panel is still connected to the TV, you will need to use a suction cup to remove the layers of the screen.
Check if your TV’s capacitors are faulty
Whenever you see a flickering or black screen on your Samsung TV, check if your TV’s capacitors are faulty. Having bad capacitors can cause sound problems and picture quality issues.
You can check your TV’s capacitors by unplugging the TV from the power source and removing the back panel. Once you remove the back panel, you will find capacitors located underneath the power supply board. Depending on your model, you may be able to replace them.
Before you replace the capacitors, take a photo of the board. You should circle the points on the board that are causing the problem. Then, you will need to find a replacement capacitor that has the same voltage and temperature ratings as the original.
To replace the capacitors, you will need to remove the power supply board from the back of the TV. The board will be secured to the chassis with a solder joint. You can use a soldering iron to melt the hard solder. Then, you will need to bend the two leads of the capacitor backwards so they protrude about 1/8″ from the board.
You should also note the direction the white stripe of the capacitor is facing before removing it. Then, you will be able to mount the capacitors on the terminal strip. You should secure the capacitors so they do not interfere with other components.
You may be able to replace the capacitors on your TV by following the manufacturer’s instructions. It is important to remember that replacing technical components on your TV is a very delicate process.
Check if your connection between your Samsung TV and your Samsung OC Box is not bent or pinched
Getting the Samsung One Connect Box and your TV to play nicely with one another is no easy task. However, there are some things you can do to improve your viewing experience. This includes turning off and turning on your television as well as resetting AV connections. The aforementioned are all things that should be done before you plug in your TV, but if you have already done so, the next best thing is to test out your connections.
You may already be aware that the Samsung One Connect box was designed to simplify your TV connection experiences. Before you power on your television, you should make sure that the One Connect Box is connected to your television panel. In addition, you should make sure that you have all your cables tucked away in their respective places. To test this out, you may want to use a different HDMI cable than your TV’s standard cable. This will make sure that you don’t have to rewind your cables to find the aforementioned tangles.
If your TV is displaying the Samsung One Connect box’s stock picture, then your next step should be to test out the HDMI cable’s tangles. If you’re not lucky enough to have a TV with a built-in HDMI port, then you’ll need to rely on your handy dandy HDMI cord to do the trick.
You should also check out the One Connect box’s Optical Cable port. Using this port will allow you to connect your Samsung Galaxy S5 to your television without having to fiddle with a USB cable.
Troubleshoot a Sharp TV that isn’t turning on
Getting a Sharp TV to turn on can be a challenge. It can be an issue of hardware, software, or firmware. These problems can be frustrating to say the least. Luckily, there are several ways to fix this.
The first thing to do is to unplug the TV from the wall. Hold down the power button for approximately 25-30 seconds, then plug the TV back in. If the TV still won’t turn on, try to plug it into a different power outlet.
Another option is to try a power cycle. This will reset the TV to its factory settings. If this doesn’t work, it’s time to call for help.
A defective power outlet may be the cause of your Sharp TV not turning on. Make sure the outlet is plugged into a power source that can supply enough power for your Sharp TV.
If your TV is still in the standby mode after you unplug it, you can try turning it on using your remote. If that doesn’t work, it might be time to try a hard reset. This will return your Sharp TV to its factory settings.
Another way to troubleshoot a Sharp TV that won’t turn on is to look at the power board. This can be done with a multi-meter. If the voltage isn’t too high, you may want to try replacing the power board. If the voltage is too low, the power board may have been damaged.
