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 want to save the channels and turn my antenna to another direction and scan I loose the channels that I had can I save them some how?


The only way that I solve this issue is to write down the channels available from one direction on paper. Do the scan in the second direction. Return the antenna to the first direction and then manually add the rest of the channels. Depending on the TV, you either type in the channel number with the remote control or find a Add Channel option in the TV Channel sub-menu.

At least with my TV that doesn't have an Add Channel option in the Channel section, going to a digital channel with the remote doesn't store the channel number if the signal isn't strong enough for the tuner to resolve. Analog channels can be added when the signal is poor.

If you know all of the local channels in each direction from AntennaWeb ( http://www.antennaweb.org ) or TvFool
( http://www.tvfool.com ), you can use that documentation to add the channels at each antenna direction.

I hope this helps. If you use an electronic antenna rotor with a remote control, you may be able to program turning the antenna automatically when you change the channel. Check the documentation for the device to program this.

(Note: on my TV that adds channels only when I type in the channel number, recorded digital channels can disappear from the list if if I visit a channel with poor signal strength. Until the antenna is directed towards that transmitter, I can't add the channel back into the list.)

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

How do I change Parental Control on ROKU?


Parental control is one of the features available on roku. This feature restricts the children to access the movies and TV shows based on the rating of the movies and TV shows.
Roku doesn't provide any true parent controls. But the parental control workaround is simpler one. Only a few channels on roku have the parent control. Such channels are Amazon Instant Video, Netflix, and Redbox.
Initially, you have setup your roku account and add the channels from the channel store by using the PIN.
    1.Sign in to your roku.com/link account.
    2.Click the update button which is next to the PIN reference.
    3.Then choose the choice "A PIN is required when using your Roku account to make the purchase or add any item from the Channel Store."
    4.Put the 4-digit PIN and save the changes. After that, you can watch the channel by installing them from the roku channel store.
    After finishing the watching the channels delete it.
    If you deleting the paid channels means there are no issues because you need not pay again for reinstall. For re-install it you have to sign in again.
    For some channels which have parental control, that doesn't require to delete the channel after watching.
    If you want more information about the roku call 1-844-965-4357 to get instant help.

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.

Channels with auto tuning


The antennas on most TV's are small and so moving the TV to a nee location may have put you in a new place in the house with even less signal. There are TV antenna signal amplifiers you can buy and for $50 or less you should be able to get something half decent that will boost your signal. Are you not getting any channel's now? Because you should still be able to get at least something in the new location. I'm just asking if you're getting any channels in hopes you didn't damage the TV while moving it?
