Everyone is familiar with the irate cry, “Why won’t my television power on?” As it happens, most of us have experienced at least one instance of our TVs’ stubborn resistance to turn on.
In this essay, we’ll examine a few of the most frequent causes that may be causing the problem out of a number of plausible suspects for this frustrating situation. Additionally, we’ll offer workable solutions that can be applied to fix the problem, as well as troubleshooting advice designed to hasten the process of getting your device back to full functionality.
How to Turn On TV?
If your television display is stubbornly unresponsive, you might discover that a reset is necessary. To do this, first unplug your TV from the wall outlet and wait for 60 full seconds. Press and hold the power button on your TV for 30 seconds after turning off the power source. Continue by re-connecting your television to the power source once one minute has passed. It should restart without any issues!
It’s important to note that this method works with any brand or model of television; whether it’s a Vizio, LG, Samsung, Sony, Toshiba, Hisense, TCL, Emerson, Sanyo, Westinghouse, Insignia, Sharp, or another, the simple process of performing a soft reset can successfully fix the problem.
TV might be OFF
The first thing to do if you’re having problems turning on your TV is to make sure it’s not off. In some cases, the easiest fix—unplugging it and then plugging it back in—will work. Additionally, you can turn on some TV models by pressing the power button located on the front.
Unplug TV from Wall
The easiest and most popular technique to fix a TV that won’t switch on is to unplug it from the electrical socket. Prior to plugging it back in, be sure to wait the whole 60 seconds.
While you wait, drain any remaining power from the capacitors by pressing and holding the TV’s power button for 30 seconds. Instead than just turning the remote on and off, this easy step enables the TV to soft reset itself.
Reconnecting the TV’s power supply should cause it to turn on without any problems. There might be other options to try, though, if this doesn’t work.
Factory Reset TV
The more complex technique of doing a factory reset on your TV should only be used when all other attempts at troubleshooting have failed. Follow the detailed instructions for your TV’s make and model to do a factory reset. The reset option is typically located in the TV’s menu under “Settings” or “System.”
Make sure to back up any crucial data before performing a factory reset because it will erase all of your TV’s settings and data. Additionally, you will have to re-do the initial setup steps just as you did when you first purchased the TV.
Factory Reset TV Without Remote
You may still execute a factory reset on your TV using the buttons if you don’t have access to the remote control. Depending on the model, these buttons may be found on the device’s bottom, right side, or left side.
Do a Google search for your TV’s manufacturer and “factory reset without remote” to learn exactly which buttons to push and in what order.
The TV will shut off, restart, and return to its default settings after a factory reset. Normally, the reboot and reset procedure lasts about one minute.
After attempting these methods, if your power problems persist, you can try a few more troubleshooting techniques before giving up.
Wrong Input Channel
It’s possible that an erroneous input source is to blame if your Sony TV doesn’t seem to switch on. You must choose the right input source for your TV in order to resolve this problem.
Whether you’re using a streaming device, DVD player, or cable box, check that the HDMI port number on your TV matches the source or input.
Here are two techniques for choosing the right input source:
Using a remote control, activate the input source
- Turnon your television
- Put your remote control’s Source button into action.
- Choose the preferred input mode.
Change the input source without a remote
- Turn on your television
- On the TV’s side or bottom, press the MENU button
- To access the source menu, use the volume button.
- Select the preferred input source by pressing the menu button.
You can choose your preferred input source by pressing the source button on some TVs, which are usually located on the side or rear.
Plug Tv in different electrical outlet
Check the TV’s circuit board for any obvious damage or loose connections if you’re still unable to get the TV to turn on. Only someone with technical expertise or knowledge should try this step since handling circuit boards improperly can be deadly.
If none of the aforementioned solutions work, you might want to get in touch with the manufacturer’s customer service for more advice or to arrange for a repair appointment.
Ensure power cord is proper
If your TV still won’t switch on, you might want to see if the power cord is damaged or broken. Make sure to check both ends of the power cord because it may occasionally have come unplugged from the TV or the wall socket.
You might need to buy a new power cord if you discover that the old one is broken or damaged. It’s crucial to use the proper kind of power cord for your TV, so be sure to consult the owner’s manual or get advice from the producer.
Try directly plugging the TV into the wall outlet if you’re using a power strip or surge protection instead. These kinds of gadgets can occasionally disrupt power flow and prevent the TV from turning on.
You ought to be able to quickly get your TV working again by trying these various fixes.
When all other options have been tried and your TV still won’t turn on, it might be a good idea to see if there are any manufacturer updates available. Updates may include bug fixes or other improvements, making this especially crucial for newer TVs.
By choosing “Software Update” or “System Update” from the TV’s settings menu, you can check for updates. To finish the update procedure, adhere to the directions displayed on screen. If an update is available, downloading it could solve the problem and restore your TV’s functionality.
Replace Power Supply
You can try to take out the TV’s power supply and send it in for repair if all the other efforts have been unsuccessful and you’re determined to keep your TV. However, make sure your TV’s standby light is on before attempting this. If it is, skipping this step is advised because the power supply board is probably operating correctly.
Your power board is probably dead or defective, possibly as a result of a power surge, if you have no power and no standby light. Despite the fact that many TVs are notorious for having broken or insufficient power supplies, fixing one costs only about $65 if you remove the board yourself.
The power supply removal procedure is described below, but you should be aware that it takes a while because you must unscrew each of the screws holding the TV to the wall in order to get to the power supply. Furthermore, there is no assurance that the power supply is the root of the power problems, so proceeding with this step carries some risk.
Backlight is Broken
Your TV’s backlight might be damaged if all of the preceding attempts to get it to turn on have failed.
By turning on your TV and then bringing a torch extremely close to the screen of your TV, you can test to see if this is the case. When you flash the light, pay close attention to see if there is any image on the screen.
If a very dim image starts to show, your TV’s backlight is definitely broken and has to be replaced. This is a more complicated fix and may need for expert assistance. To get an idea of the cost of repair, check with the manufacturer or a reliable repair provider.
Motherboard is Broken
It’s possible that your TV’s motherboard was harmed if there was a recent storm. You must take the TV’s back panel off to verify this. There will be several boards visible, usually with the power board on the right and the motherboard on the left.
Plug in your TV and turn it on to rule out the power board as the source of the problem. Then, from the side of the power board, remove the cable that connects the motherboard to it. If your TV is still on, you know the power board is working well and your motherboard is broken.
The cost to repair a motherboard is typically low, but you should check the board’s serial number to be sure you get the right replacement. If you are uneasy performing this task on your own, think about getting help from a TV repair expert.
Use TV Warranty
Yes, if you’ve tried everything to fix your TV and it still won’t switch on, you should see whether it’s still covered by warranty. A excellent place to start is by getting in touch with the manufacturer or the shop where you bought the TV.
Depending on whether the problem is covered by warranty, they could be able to provide repair services or even a replacement. It’s always worthwhile to give it a shot to see if you can repair your TV rather than buying a new one.
Wrapping it up
Before giving up and purchasing a new TV, you can attempt a number of troubleshooting techniques if your TV won’t switch on. Before plugging your TV back in, first unplug it from the wall and wait at least 60 seconds. You can also try factory resetting your TV with or without your remote by taking out the batteries from your control and holding the power button for 15 seconds. If it doesn’t work, again verify your TV’s input source selection and make sure the power connection is securely attached to the back of the TV.
If none of these solutions work, you can also try a different power outlet, a new power supply, repairing the backlights, or a motherboard replacement. It may be time to verify your TV’s warranty or think about buying a new TV if none of these repairs succeed and your TV still won’t switch on.
