I have an HD Flat Screen TV and when I turn it on it says NO SIGNAL. I have not seen this before as my CABLE BOX is connected and turned ON. I do not know if there may be something wrong with my Samsung TV or if it is the cable box causing my problem. I know my TV works because I can see it displaying the words “NO SIGNAL”. Is there maybe something wrong with the TV where the cables go in on the back of the TV?
TV NO SIGNAL
If your TV displays a “No Signal” message on the screen (HDTV or Standard TV) it could be one of the 4 issues we have listed below…
1 – Is the NO SIGNAL issue happening on just one TV?
CORRECT INPUT or SOURCE
If it is just one TV that is showing the NO SIGNAL…
-Be sure your TV is on the correct source or input as your CABLE or SAT BOX.
-Press the TV button on TV remote control to turn your TV ON.
-Press the INPUT button on your TV remote control.
-Cycle through all the inputs on your TV.
-Do this until you are on the INPUT your CABLE or SAT BOX is plugged into.
-You should then see the CABLE or SAT programming show on your TV.
HINT: Your TV will most likely list the TV INPUTS as: HDMI 1, HDMI 2, HDMI 3, VGA, Component 1, Component 2, and so on.
If you still see NO SIGNAL on your TV screen, see the next step below…
2 – If you have your TV on the correct INPUT or SOURCE and you still see NO SIGNAL…
CABLE OR SAT BOX NEEDS RESET
-Remove or unplug the power cable from the Cable TV or SAT set top box.
-Keep it unplugged for 2 to 3 minutes.
-Plug the power cable back into your Cable or SAT set top box.
-Give it some time for the Cable or SAT box to power up, get the signal, and initialize.
If you still see NO SIGNAL on your TV screen, see the next step below…
3 – If you have reset the Cable or SAT box and still have the NO SIGNAL…
UNPLUG THE CABLE GOING FROM THE TV TO YOUR CABLE OR SAT BOX
-Remove the HDMI cable or other cables from your Cable TV or SAT set top box.
-Keep the cable unplugged for 2 to 3 minutes.
-Plug the HDMI cable or other cables back in.
-Give it some time for the Cable or SAT box to get the signal and initialize.
HINT: Make sure all the cables that are connected to your Cable or SAT box and your TV are tight, undamaged, and secured.
4 – If all of your TVs are affected with the NO SIGNAL screen…
BE SURE THE COAX CABLES OR ETHERNET CABLES ARE SECURE or CABLE OR SAT IS DOWN TEMPORARILY
-Be sure to check the ones where the CABLE or SAT come into your home.
-Be sure ALL Ethernet and Coax cables are secure.
-Call your CABLE or SAT provider to see if there is an outage.
-Realign your Dish if you have SATELLITE.

I have done everything that was required including talking to my cable provider which stayed there were no outages or problems with my wifi or internet. I am in need of help at this time.
My TV Samsung was doing the same thing until I reprogrammed all the channels.
Not in the setup but on the menu (plug and play).
There is a video on youtube from SAMSUNG that guides you on that particular problem.
My suggestion will be to try different inputs.
Try connecting your cable box to another TV.
Last but not least you may have a bad Main board on your TV.
I have no signal on my TV.
This happens a lot.
I’ve always corrected it.
I’ve tried rebooting all the channels and everything.
But this time nothing it is not working.
Ive tried all the steps above and nothing has worked. The TV Is set on the right channel, I’ve reset the direct TV box , I’ve unplugged the cords from the TV and nothing has worked. When I reset the box it pops up on the TV that’s it’s restarting but once it does it goes back to saying no signal. What else can I do?
My tv keep on saying no signal, even after I followed all required step trying to fix a problem but no changes. Pls help.
We have just moved into a newly converted property. We have the coaxial cable plugged into the wall and into the tv as it has freeview built in.
We are getting no signal and have tried two cables, we are not sure what to do! Please help.
My LG tv is playing Netflix and while playing Netflix a box shows up that says no signal but I can still see the show playing and then my tv cuts off. I’m playing Netflix through the app on my tv. Why is it doing this?
