TV Says NO SIGNAL – What To Check – How To Fix

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?

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.

  1. No signal on my Tv. freeview box went off. No light on. Tried removing cables and unconnecting putting aerial lead direct to to have checked fuses, unplugged everything but still say no signal

  2. I have a Sony TV on an antenna. Was working find last night. Today says no input check cables etc.

    Input and cables is fine. If there is no connection why does it tell me the channel and network I am tune too? I can change to all 70 channels over the air here and each one shows its channel and network name. But no sound or picture.

  3. I have 2 TVs- 1- bedroom and 1 front room. Both working fine last night. Today – ‘no signal’ – tried disconnect wires into tv arial on wall and turn off mains – nothing. Tried to retune TV – no channels found. On the bedroom TV cant even find retune on menu. Nothing im doing is working. I live in a block and no one else has complained of this issue? any help would be appreciated

  4. My OpenView HD decoder is giving me a no channel error message it’s two weeks now called in an installer who said my decoder does not transmit power to the LNB as he couldn’t get power when signal finder was plugged in…I called the call centre and given prompts to follow to no success tried to reactivate the decorder…it can back after 72hours of being switched off then lasted for few hours to date it says no CHANNELS… SAD

    I am unable to get the free TV channels on my TV…it was working last night and this morning it is not working anymore…it says NO SIGNAL. We did unplug the cable from the cable box and the antenna plug from the wall behind TV for at least 3 mins. After that we plugged back all the cable and tried after 2 mins…it is still the same.

  6. Our TV signal has been intermittent in the last week, high pressure gets the blame, but at 8pm last night it went off with no signal, tried to reset this and no channels! We get the Stockland transmitter in Swest. There is a booster in the loft, could this have suddenly gone?

    Amanda,
    It seems as if your TV is set to go to a certain HDMI input when your TV turns on.
    Try removing the HDMI cable on the TV from input 2 and plug it into the HDMI input 1 next to it.
    This should make it so when you turn the TV to ON, the image will appear instead of having to change the inputs with the remote control everytime.
    -RR
