My Vizio TV won’t show the cable channel. Just a blank screen. The cable guide displays and the dvd will play but no tv or cable display..

most likely you have a bad signal and the TV is fine

note as of a few weeks ago Spectrum has discontinued the ability to you use the screw in cable for tv usage you must upgrade with your carrier. The only thing you can use now is an antenna over the air for your tv in coax connection. also the TV settings menu must be set for antenna not cable then do a cable scan and you will get what over the air signals are avalable

It keeps saying no signal check your connections and correct source. All connections in place and the source is correct. But still showing "no signal" message. Many thanks. Margie

It's possible that you have a bad port on the television. If possible, move the cable (is it HDMI?) to another port on the tv. When that is finished, change the source to the new port and see if it works. Also, some devices, like DVD players, won't show up unless they are powered on. If that doesn't work, try replacing the cable... although rare, even HDMI cables can go bad.

My digital tv is saying no singal whats the problem and how do I fix it? we have a huge antenna on our roof

1 – Is the NO SIGNAL issue happening on just one TV?
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…
-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…
-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 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.

My dynex flat tv dx-l26-10a keeps showing "no signal" how do i fix that

Hello Steven,
I am sorry that you are having this problem, but I have a few ideas
in case you haven't tried them yet. If your TV is WI FI capable call your service and ask them what might be able to do for you.
If your computer is HDMI capable you can connect your computer to your TV.
You can also connect the TV to your Modem or router.
Just make sure your internet provider is servicing your area.
Especially If your computer's signal is lost too.

And I just recalled another minor thing, Press the input button on your remote and see what happens. Depending on your cable connections in the back, like my TV, I have to press input to get the HDMI cords to function where I want them too. Here is an example:
Input# 1 TV: Regular TV will come on. input# 2 DVD and input# 3 shows what ever is on my Computer, will show on the TV.
My TV also says no signal if either one of the parts are not on.
We have to turn on the DVD player to play DVD's. Our Computer is always on, But if it goes in sleep mode, the TV will say no signal.
Hope this helps. God bless you. And Happy Thanksgiving -Lena

Sharp tv won't display cable picture (it only shows fuzz) but the netflix and DVD both work. The cable says no input service available. I am able to change the channel on the cable box, but on the tv

Your cable box might not be sending signal out to the tv. Would have to call service provider to have them test your box. Or, you can try unplugging your cable box, and then plugging it back in. Make sure all connections are secure and settings on your tv are accurate. 11_13_2013_3_31_52_pm.png

No signal. It keeps saying invalid format. I have tried changing the tv format to 1080i, 480p from the cable box and still won't get the right format.

1 - Turn on TV and set input to port being used.
2 - Make sure PS3 is connected via correct cable.
3 - Power on PS3 via power button and HOLD IT for 5 seconds (release after the second beep). It should automatically configure your PS3 to the TV's native resolution for all settings.

please do the follwing above,

best of luck to you,

My ps3 won't show on tv but it show that it's playing

Are you saying that it has sound but no video?

Plug only the video plug (yellow) to the TV. Turn on the backswitch. When the red light in front is on, put your finger on the on/off button in front AND KEEP IT THERE. You will hear some beeps; don't worry about that. Keep your finger on the button until the front power light goes red again. This resets the PS3 video settings. Turn the PS3 on and the TV should pick up the signal.

Hope this helps. Keep us posted.

No signal and theres signal

sounds like you need a new tuner replaced or the ssb(small signal board) inspected. The tuner recieves the cable signal and converts it into an intermidiate signal which in turn the ssb processes into audio and video signal.

Green box keeps popping up in upper right corner

You should be watching your dvd's on an input and not on tv analog 3. Every time the tv "senses" a signal change in the audio that screen will pop up. Connect the DVD player to the tv by using either the red, white and yellow (composite) connections or using the green, blue, red, white and red (component). Once you are on an actual input that box will stop popping up.
