No signal. Antenna works on other TV's but not this one.

My TV just says no signal. I bought a new antenna and still, no signal. I tried both antennas on another TV and the antennas work great. I have turned everything off and turned it on the next day. Unplugged and replugged the next day also. I have nothing connected to this TV except an antenna. I tried every input and all I see is no signal. I'm guessing this means the TV is useless? I have tried every clue I could find online . Help?

JaNelle JG "I have nothing connected to this TV except an antenna" try other input souces like a DVD player or a game console etc. and try other connections like composite and HDMI etc. Let us know what you get with those. Like @jayeff already mentioned, it is possible that this is an antenna issue but it is also possible that it is a main board issue. That is the board that has all the connections on it.






Has the TV worked OK before when connected to an antenna?

If so, was there a power outage or storm before the problem occurred?

Have you tried connecting a different type of signal source to see if that works, e.g. a DVD player or game console, connected to the HDMI or AV ports?

If another type of signal source works, check that you have selected Antenna and not cable in the Tuner section of the Settings menu.

Go to Menu > Settings > Tuner > select Antenna > OK

Here’s an image taken from the user manual for the Vizio E420-A0 TV but it may be similar for your model if yours is a different Vizio model.

If it is only on the antenna input that it doesn’t work or even on all input types with different signal sources then it seems as though the mainboard may have a problem.

What is the full model number of your TV if it is different to what is shown next to your question above?

Thank you so much for answering my question. I've tried both cable and antenna. I will try hooking up a DVD player and see if that works. I'll get back to you Monday. Thanks so much!
