Digital channels come and go for no aparent reason. One day I will have 16 off air digital channels that the auto channel search finds and saves. While tv is on it never loses signal but for some reason, when the tv is turned off for the night it loses the digital channels. The next day and sometimes two or three days after the auto channel search won't find any channels. I will keep trying, and eventually they come in again, till the next time the tv is turned off again. I'm thinking it's the tuner box that is malfunctioning for some reason.

Re: off air digital signal
What brand of tv is it ? You could have a bad tuner or a change in the voltage supply line feeding the tuner . What type of antenna do you have ? outdoor or rabbit ears ? Also does it retain the channel line up or does it clear them as well ?

Make sure you are connecting the digital antenna to the digital antenna input on the back of the set, then rescan. Most over the air Tv signals migrated to digital transmission and therefore the analog input is mostly for older analog devices. If you still do not get any channels, then you need to make sure the antenna you are using is rated for reception in your area. You can check for proper antenna size and channels available here,http://www.antennaweb.org/aw/welcome.aspx
If ur tv a LCD tv it is a digital tv.U do not require a Digital converter box to get the new DTV free air signal broadcasting tv channels stations.But u do require a good digital antenna for it to recieve a long an strong signals to recieve a DTV free air broadcasting tv channels stations.
As of 6/12/09, the over-air broadcast signals went to digital (ATSC) only. Your set does not have and ATSC tuner so it can not receive the new digital signals. The converter box converts the ATSC signals to the NTSC channel 3 or 4.
This TV will need a converter box. It was made in the days before the digital tuner was required on big TV sets.
Just remember the converter is only needed if you get off-the-air reception with an antenna for local channels. If you have cable or satellite and get your local channels that way, you don't have to do anything. The change to digital will not affect you.
If you are now using rabbit ears or an old worn-out outside antenna, you might think about upgrading your antenna when you get a converter box. Signal strength is very important with the new digital broadcasting. Too weak a signal means no picture at all or one that freezes up or turns blocky. The antenna that worked for analog may not be adequate for digital.
Initially, pls confirm if below is how it is wired using a coaxial cable and not 3cable RCA to RCA:
Charter Digital Cable > DVD/VCR > TV
If yes and your concern is snowy or no signal on the TV screen, might it be that you have to power OFF the DVD/VCR when selecting channels on the TV itself (including when channel setup is being done).
Alternately, you can tune the TV to channel 3 and let the DVD/VCR do the channel selections.
Pls post back results. Good luck and thank you for using FixYa.
The easiest will be to make sure that the cable box is on and sending out a signal to Channel 3 and auto-programming the set. Channel 3 is skipped because the last time it was auto-programmed, there was no signal on that channel.
I'm sorry, but I have not worked with Grundig TV's, radios yes, TV's no. However, The menu shouldn't be hidden. The first thing I would try would be to UNPLUG the set from the wall, wait about a minute and plug it in again. This action should reboot the micro processor. On some sets, there are two levels of menus, main and advanced. You would want "channel setup" and /or channel scan. You may also look in the back of the manual and see if it list some service dealers that you could call for help. I hope this helps. Electrode
