Video channel disappeared

Our video channel disappeared.
we only have one antenna but two televisions, so when my parents were visiting we moved the antenna to the other tv.
then when I moved the antenna back, I could only see the video channel.
I did a channel search and got up all tv channels, but then the video channel was gone.
I have looked at all menues and I also put the game mode to "on" but the video channel is totally gone??? the tv just jumps over it from 69 to 2.

I dont have a remote and im trying to set up a digital tv antenna but the only channels im getting is 3 and all the video inputs. How to i program channels


Hello,

Usually channel 3 is picked up on a channel scan when there is an input device connected to the TV via a Coaxial Cable, thus using only channel 3 on the TV itself and using the Digital converter box to tune in the channels.

The TV will need to be Digital ready to connect only a Digital Antenna to it and programmed to receive the Digital Broadcasts over the air. If you are certain that this TV is Digital Ready (TV manufactured from 2009 to the present) you can use the menu button on the top, side, or front of the television, then use the channel / volume buttons to move around the menu, and the input button as the enter button.

You will want to select Antenna (ATSC) signal before starting the auto program so the TV will be able to recognize the Digital Channel Broadcasts.

Hope this helps!

Cheers,
Scott

Can not get some channels any more


Hello

This might occur due to the following

1. Your antenna/receiver is not properly connectec to the back of your television or not connected at all so check the back of your television and connect it properly

2.the channels you are getting are probably not on air at the time you checked so give it a little time and check again

3.if you are using pay per view or pay tv you might have run out of air time and your channels have been locked due to non payment.all you need to do is to go and subscribe and your channels will be on again.

You may also have enabled parental view on your tv and that is why some stations are locked so consult your tv manual to see how to disable parental view

Need the unlock code to get channels on the t.v. model ku-27525. yr1996. sony trinitron..*** we're in desperate help..please


Have you used Parental control to block channels?
Maybe just go into the TV menu and unlock there.
If not and the TV is using a cable or Satellite box then just use Video 1 or others even channel 3 to get the channels from the box.
Today we have a lot of free digital TV from our old roof antennas you might look into that.
My own Cablevision on Long Island ,NY has lost 5 and 9 due to a dispute with their source but who cares I have digital from my roof antenna put up in 1965. Please let us know if these ideas helped.

Can't hook up Comcast cable box into tv. It is an HD comcast cable box and I am trying to hook it up to my childrens princess tv/dvd combo. I can't figure it out. Please help.


I assume this TV has no Audio In and Video In, from your Cable box there's an antenna out or cable out, connect that to your TV's antenna in, and make sure that your TV is tuned in to channel 3 or 4, try those two channels. You can only change channel thru your box, your TV channel is alway's on channel 3 or 4.

Tv suddenly shows no audio and no video for digital channles only yet all digital channles are detected durring the channel search


Sounds like you have a bad signal from the antenna or the cable. Unlike analog TV if the signal level drops below a certain level you loose the picture and sound completely. The fact that digital channels are detected during channel search does not mean they have a good signal. Try moving the antenna about.

Channels disappearance.


If previously some of your channels were freezing or pixilating etc. this indicates a problem with your signal hence the reason why some of your channels have returned, this depends on the strenght of the sincoming signal. Check your antenna connection & cable if that doesn't help, then check your antenna has not moved off alignment & if so re-position it.
