Why tv turns itself off

It was working fine until a couple days ago it randomly shut off on its own. I turned it back on and it was fine but it keeps shutting off every couple minutes after I turn it on. I am having the same exact problem with my RCA which is only about a year old. Exhausting all options, I would make sure to post here if I do. My Emerson tv will not turn on I press the on button and my and the red light will blink and then it will go black and then it will go back to red but the TV will not come on.

I have a 60 inch Vizio TV that keeps turning off. It used to turn off every now and then and i could just turn it back on. But now its doing it more often. I used to just unplug it and plug it back in and it would come on.

I know trying to get it fixed is probably going to be expensive. I am trying to see if i can fix it myself. I have a kenmore elite 55 tv and it randomly shuts off. It happens in 15 or 30 minute intervals. I have a Magnavox flat screen TV. I have Comcast cable and occasionally ps4 is hooked to it. But,it shuts off constantly.

But will shut off again. Please help me figure this out. I have same set up with PS4 mine doing same thing I unplugged the TV to pull off the wall and when I did I notice the the plug was melted and burnt I cut plug off and replaced with new one and now works fine so might wanna check plug in. Been doing that for a couple days now. Have sound but no picture. Then restarts on its own again.

My vizio m series 65in is doing this. It turns off randomly than turns back on..?? Any fix for this??? I have a 22 inch LG TV flat screen which turn off by itself for about three month now after displaying that this system will shut down in ten minutes time. I have a 52 inch sanyo that powers on, and about 8 seconds later turns off.

No time for the screen to turn on. I tried all the suggestions above and not resolved my issue. Do you have any other suggestions? After being on for a time and then turning it off, I can turn it back on within about 2 hrs without any problems. Otherwise, if I wait longer between turning it on, I have to go through times turning it on before it stays on. I have a 55 inch flat screen rca…it eont let me in the menu after i turn the tv on…..

Okay, my 55 inch flat screen TV turns on normaly with remote and by TV. What could be causing this to happen? We have an element TV and it shuts off after a few seconds. Not enough time to get to the settings menu to reset. Not sure what to do. I have a flat TV Screen, The power light shows up but there is nothing displaying on the screen. I try pressing the remote controller but nothing came back but just the black dark screen.

The previous night I accidently set the Sleep timer button to seconds. The next night trying to put on the screen nothing came on except the power light. I tried turning off the screen using the screen Power Button but it seems to be freezing.

Nothing happen, just the power light — Red plus the Black Screen. My 55 inch Magnavox flat screen will come on for about 4 seconds then cuts off. I disconnected it for a month, and by curiosity I tried to put it on, it worked very well for half an hour then turned off by itself. NB for a year now there is a thin green line, not so observed, from the top to bottom of the screen. I had been told it is a burned screen???? But how if it turns on ok if left off for a while!!!!

I have a Toshiba 42HL, the TV will power up and the light in the front will turn green and the light behind the back cover the sound board I think is green, after 20 seconds the power board will click and the screen will go black, the green light on the front will remain green but the green light on the sound board will go out for 1 second then come back on green, after 5 seconds the speakers will make a ripping sound then 5 seconds later the power board will click then screen will come back on, and will continue to repeat the process.

Mike, Sounds like you may need a new sound board or a power board for your Toshiba TV. Do you have a multimeter? So I feel there is hope but it still powers off after about ten seconds so I am unable to go into menu or any settings. In reading others comments I think perhaps there is a defect in the power board. I am not very savvy but poor enough to try to be. How can I order the board or capacitors?

And do you agree this is where I should start? Video and audio works fine with all HDMI connections but when I plug in an antenna or anything else into the coaxial input the tv will suddenly turn off and on by itself with a white line across the screen, sometimes at the bottom, then the middle, then the top.

This erratic behavior will continue unless I disconnect the antenna cable from the coaxial connector. I also tried resetting it. I have a Luxor smart TV which works perfectly well except when I try to connect to the internet either via WiFi or wired the TV switches itself off if I keep the Ethernet cable in it will turn on and off until I remove the Ethernet cable.

Our tv turns off every hour on the dot unless we are watching hulu, netflix, amazon prime, etc. No timer is set. We thought it was the tv but have purchased a new one and it does the same thing. We have plugged a lamp into same outlet and it never flickered.

The cable box does not turn off either, just the tv. Without ever touching any buttons. Just repeatedly cycles on for about 10 seconds, then shuts itself off, for about 5 seconds, then back on. Did you fix it??! Mine does same thing but less seconds!

Maybe 4 seconds you see the logo on the screen and then turns off. I have a Hitachi TV 42hdx It turned itself off after about an hour, had to unplug and plug back in to get it working again. Then it turned itself off again after about 10 minutes. Unplugging seems to temporarily reset issue but not fix the problem. I have the same problem. When I power it back up the red light turns on for several seconds and then the blue light blinks 11 times and then it works for a while again.

Is there a solution to this problem? Is there a chance that droplets of water reach the cord of the tv causes it to turn off suddenly? I heard a loud pop when it off.

Cath ongayo, If using a hair dryer plugged into the same outlet as the TV, the TV turned off, you simply over-amped the outlet. Plug it back in then turn the TV back on from the Power button.

Maybe, but chances are it's neither, and you can easily fix the problem. At Asurion, our experts help millions of customers get the most out of their tech and resolve their device problems. Here they'll answer why your TV keeps turning on and off by itself and what you can do to stop it. That question may sound funny, but if your television seemingly has a mind of its own, you're probably not laughing.

The good news is fixing this problem is simple—as long as you can identify the cause of it. First, unplug your TV and take a close look at the power cord for damage or fraying. If you see damage, safely remove the cord and replace it. If it looks okay, make sure the cord is firmly connected to the television and plug it back in. You may also have an issue with your outlet.

Try plugging the television into a different socket, preferably one not connected to a light switch. Or it could be a problem with your surge protector; if you've been using one, unplug the TV cord and connect it directly to a wall outlet. Take a look at your clicker, especially the power button. Is it stuck? This can happen if you or your family members have spilled something sticky on it.

Try cleaning your remote until all the buttons work properly. To do this safely, first remove the batteries and shake loose any debris between the buttons.
