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 am getting problem in my tv some channels in between stucked its showing ” NO SIGNAL CHECK THE CABLE CONNECTIONS AND SETTINGS
I was watching all afternoon. Turned TV off for dinner. Returned after dinner and turned on TV again. Now it is showing NO SIGNAL. SPOKE TO Fios customer service rep (hard to understand) and we went through the same steps over and over. Still no correction of the NO SIGNAL issue. Why do we pay these high costs when we cannot watch TV when we want to do so? Tech scheduled for tomorrow. One time this happened and Customer Service Rep on the phone sent a signal and “walla” I had service again.
im having the same problem and step 3 works.
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 i just want to ask
i just want to ask why does it happen? i didnt even touch the cable connecting from the tv to my cable box then suddenly the tv cant get a signal from the box. when i do the step 3 (or rather change the cables – the one connecting to the tv goes to the cable box then the one in the cable box goes to the tv), it works. but this happens often now. im just wondering if it’s my cord (video/audio cable) or my cable box that have a problem.
Thank you so much for this update. Closest I’ve seen to any reply on the ‘no signal’ TV issue. We had pixels that were not working properly already, so I’m going to try the TCon board, almost certain, you answered and solved our issue. Thank you.
I have a Vizio tv, 15 months old and having the issue with “NO Signal”. I tried all the step listed above and nothing is working. What is the next step?
I have no signal and had my cable provider come out. They said HDMI cable is. I replaced same No Signal. Could the tv be bad? I’ve unplugged replugged etc. rebooted also
