How to get regular TV channels?
Your HDTV should have a digital TV Tuner (ATSC) which may need an indoor antenna. Change your TV's input selector to TV or Antenna or Digital (probably one of those three) and scan for channels. If you don't get any channels, then you do need an antenna. Probably another $10.
With the HDTV set for an HDMI Input that matches the HDMI Jack that you've connected to the cable HD STB (set-top-box or "converter"), use the cable STB remote to change channels on the STB - not the TV.
You can not change channels of the STB with your TV remote. You may however, be able to program your STB remote to operate your TV. Most will allow you to power the TV on / off; volume up / down / mute; change input (HDMI1 / HDMI2 / ANT / Composite / etc.) and even some of the more complex functions as well. Contact your cable company for more details.
Try changing channels with the button on the TV to make sure the remote is not bad. Sometimes one or just a few buttons on the remote will quit functioning. It is usually the ones that are used the most. What channel is the TV on? If it is 3 or 4 or one of the aux inputs; it may have been told to stay that way because the channels were changed by a cable box. Go to set up and scan channels into memory. After it has started, do not stop it until it says on the screen that is finished. If you stoop it before it has completed the scan, the TV will keep its original program. (one channel)
Sounds fishy to me----almost every provider uses a box that has either HDMI or Component outputs for HD--your set should if HD ready have a Component input for that also--if it only has the HDMI for that you may be out of luck. Check the owner manual to see if one of the Component inputs is HD or not.
What type of antenna are you using? Or what is your source for accessing channels? (i.e. - are you connecting to a cable tv service box or are you using a receiver ect.) Make sure that your source is connected to the input method that you are currently using on the tv.
There are many input methods to choose from in the settings of the tv. They are generally called antenna 1, antenna 2, cable, aux, hdmi - and a few other names. There should be a button on your remote to change them. The function is usually called "source" or "input". Press that button to change the input method until you get a picture on the tv or pick up some sort of reception. when you have the tv set on the same method of input that your antenna source is connected to, you will get channel reception or some sort of picture. Thats when you use the menu functions to auto find channels for you and let it go through its checking scan to report how many it has picked up.
If its running the scan for channels and not locating any stations, and the picture is either scrambled with the white noise sound tv's make when off channel or if its just single color screen without any sound - then you know the antenna input method you have chosen on the back of the tv is not the current method set in the settings under the menu key.
Most of the time the inputs are labeled on the back. If you look under the cable antenna connection, it should say "cable" somewhere in small print - or "antenna 1 input", antenna 2 ect. Look on the back of the tv. If you are using RCA jacks that are labeled right and left for sound and a third connector for video ect, look for the name of the input method of those three connections on the back of the tv. It should be marked as input - aux 1 ect. Then just change the source chosen in the tv to match it and have it auto program your channels.
If you have the remote, there should be an input or source button it? Also, check the buttons on the TV for an input/source button. If there isn't one on the TV buttons, try cycling through the channels, some TV's have the inputs change with the channel buttons too, once cycled down through the channels, it will go through the inputs before starting over.
Run a channel scan on the DTV and/or TV input depending on what one your not getting channels on. This will solve your issue.
Change the input on the unit to the DTV or TV input. Press the menu button on the remote. Navigate to the tuner DTV or TV tuner setup menu. Go down to auto search using the down arrow. go right when with auto search selected. This may take a few minutes but you should have all the channels back after the scan.
