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 just moved into a house and I have tried setting up my tv and hd set top box, and I keep getting no signal, I have brought a indoor antenna and I still can’t get it 2 work, I have got the hdmi cable connected into the right spots, I have put the antenna part into the wall socket and into the tv but still getting no signal. Someone suggested a booster cable but I’ve never heard of it and don’t know where I would get 1 from.
My TV is hooked up to cable and works fine but, when I switch it to air channels, it takes 40 minutes to come on. It says no signal, but after 40 minutes it comes on. When I turn it on and hit source HDMI, it comes on right away, but when I hit source and it’s air channels, it takes 40 minutes to come on. It gets no signal for 40 minutes. Is my TV going out?
I have a Polaroid TV, just had cable hooked up! “NO SIGNAL” had tech come back out to check cable (dish) installed correctly, still “NO SIGNAL”. I do not have the TV remote so I am in a quandary! What do I do?

My PlayStation 3 comes on but to put it back on the For Television to play, it has No Signal, I pressed the SOURCE to get an internet connection and it would not change. What Do I Do? Do I unplug everything and then plug everything back.
My LG tv still says no signal no matter what I do.
I was having trouble with the hard drive freezing and turning tv off after making a ticking sound every 3 seconds and wont let me change the channel.
If I play recorded tv I have no sound.
I also have no signal on any other components.
