A few hours after switching off your TV, it turned itself back on, making you surprised and puzzled.
What might be the reason your TV turns on without manually switching it on?
A TV turning on itself is a common issue that one can solve with simple solutions. Typically, the problem is a simple, easy-to-solve one. The power button on the remote may be stuck, or the batteries may be running low.
The problem could be caused by a connected device, such as a router, network device, or USB wireless LAN adaptor. You may have inadvertently set an internal timer to turn on the TV, and an internal HDMI or CEC setting could also turn on a TV.
Reasons Why Your TV is Turning On By Itself
There’re mainly two reasons why your TV turns on by itself:
1. Your TV program crashed.
2. There’s hardware damage.
There is a significant difference between the two, and any user can repair system flaws. You don’t necessarily need to be a tech giant before you can fix your TV turning on by itself.
The following are the most common other reasons:
• You inadvertently set an internal timer to turn on the television panel on its own.
• The power button on the remote control has become stuck.
• A device (wireless adapter, network module, or router) is connected, causing the TV to turn on by itself at night.
• The remote control’s batteries are dead.
• Smart TV turned on using CEC or HDMI settings.
Keep in mind that there are numerous TV brands in the market; this is a problem that could occur with any model.
How to Fix a TV That Turns Itself On
Following the steps outlined below, you can diagnose and fix a TV that’s turning itself on:
1. Replace the Batteries in Your Remote
If your remote’s battery is deficient, it may be sending out erroneous signals as its power fluctuates. Replace the batteries in your remote and see if that solves the problem.
Clean the remote’s buttons if the power button is sticky from when you spilled soda all over the place; it could be as simple as the button sticking down and turning off the TV.
2. Unplug Your TV from the surge protector and plug it into the wall directly
After replacing your remote’s battery and before doing anything else, try turning your TV off and on again, as you would with any other piece of technology. If the problem persists, you can unplug your TV completely, hold the power button down for 10 seconds, and then plug it back in.
If you’re using a surge protector, try plugging it directly into a wall outlet to eliminate the possibility of malfunctioning. If it’s already plugged in, try a different outlet, preferably one that’s not connected to a switch.
3. Disable HDMI-CEC
If I were a betting man, I’d say HDMI-CEC is to blame for your power issues. Consumer Electronics Control, or CEC, is a feature that allows your devices to communicate with one another via HDMI.
When you turn on your PlayStation, for example, CEC can turn on your TV and switch it to the appropriate input without you having to reach for your other remote. This fix can be beneficial, but if it goes wrong, your TV will turn on and off due to misinterpreted signals.
Disable CEC in your TV’s settings to see if that fixes the problem. Different names are associated with CEC depending on the manufacturer (Sony calls it Bravia Sync, Samsung calls it Anynet+, and LG calls it SimpLink), so you may have to look up the name your TV’s setting is called.
If that doesn’t fix the problem, you’ll have to disable CEC on all of your other devices until you figure out which one is sending out the random signal.
4. Check out the power timer on your television.
A built-in feature on many modern TVs allows you to turn the TV on or off at a specific time of day. If your TV turns on and off at the same time every day, it’s possible that a child or a cat sat on the remote and accidentally set it up. Look through your TV’s settings for the power-scheduling feature and make sure it’s turned off.
5. Turn off the Wi-Fi
Ironically, many TVs’ “smart” features can make them appear a little dumb. If your TV is linked to other smart home devices such as SmartThings, Alexa, Google Home, or Logitech Harmony, a routine or other automation may be accidentally turning your TV on or off.
If your TV has a built-in “casting” feature, your phone may be automatically turning it on whenever you try to watch a YouTube video.
Open your TV’s settings and disconnect it from Wi-Fi for a few days before going through each of these apps – if the Smart Services can’t connect, they can’t send those accidental signals.
If turning off your Wi-Fi solves the problem, you’ll have to look through your other Smart apps and devices to see if any are interfering with your TV regularly.
6. Install the latest Firmware
These issues are sometimes caused by software bugs that can be resolved with a simple update, as is familiar with all technology.
However, I put this last because TV firmware updates can sometimes cause problems of their own, so I only recommend it if it’s necessary.
If you haven’t found the source of the problem, check the settings on your TV to see if a firmware update is available. Some TVs may require you to install it using a flash drive manually; in that case, check the manufacturer’s support site to see if any updates for your model have been released.
7. Reset the device to factory defaults.
Finally, if nothing else works, it may be time to go nuclear and reset your TV to factory defaults. Hopefully, whatever setting was causing the issue will be reset to its default.
If you want to change your settings back to your preference, make sure you do so one by one, with a few days in between. If the problem reappears, you’ll be able to pinpoint the exact setting that caused it.
If a factory reset fails, contact the manufacturer’s customer service. Your TV model may have a known bug or hardware issue, and a technician may be able to resolve the issue once and for all.
Why did my TV turn on by itself in the middle of the night?
Someone has set a “wake-up” timer for TV, which is the most common reason it turns on itself. Low battery power on your remote, a stuck power button on your remote, the TV needs to be reset to factory settings, or the service provider enabling updates for your TV software are all possible causes.
Why is my Samsung TV turning on by itself?
Foreign matter around the power button on the remote control, external devices connected to the TV, and your settings are the most common causes for the TV to turn on itself. Clean the remote control if the power button is stuck.
TV turning on on its own isn’t something new; it’s a common occurrence, I’m sure, has happened to most of us at some point. I hope you found this article informative and helpful?
