My dvd/hdd has stopped receiving digital signal,

SOURCE: Toshiba D-VR650KU can't "see" digital channels

On the Notification screen with Cable highlighted I found that left clicking on Cable gave a drop down menu with TV on it for selection. The manual says that while Cable is highlighted, use the up or down arrows to get TV to be an option and then select it and Yes and enter. Hope this helps. I have other problems with my monitor on Line Out, the screen oftens turns blue indicating low or no video using Line 1 or 2 inputs.

Hello,

The ABC channels arrive on a different Harmonic than Analog signals; specifically the third Harmonic. When you auto tuned, the auto tune chip looks for stron analog channels on the first harmonic and any other strong signals. However the LG model is notably poor at capturing 3rd Harmonic signals.

Harmonics are different frequencies where the same signal can be captured. Making this overly simplified: a frequency multiplied by 2 is a harmonic and that multiplied by 2 is also of the same harmonic; inversely dividing by 2 and 2 gain and so on finds harmonics down in light wave frequencies.

You may be able to manually tune these ABC frequency channels manually (I do not know, as I live in the US and have no direct experience with this) and then add them in one by one. But, using the Auto Tune feature again will wipe those out. The same thing happens to other weak signals, which harmonic is actually (its on an offset carrier wave).

I just read of a man who built an improved antenna and put this in his attic and received ABC channels quit well. A decent understanding of Antenna physics is required, but it only took up 1.5m wide by .8m (sic) long. In a nutshell he improved his basic antenna by building his own more sophisticated antenna.

Shopping around and asking in the shops should get you an antenna add on that will work for you.

As I stated before I live in the US, and we don't have this, but I and others here at fixya have various experience in amateur radio.

I will ask a friend of mine who lives in Australia to confer with me on this problem of yours so he can add some value to our response to you.

Regards,

You do not need to use an RF modulator if you have a LG DR787T. It will output the program on channel 3 or channel 4. If you have another recording machine, I think you may need to re-scan for the stations.
It is also possible that you need to use the remote to switch from the analog (66 only?) stations to the digital stations.
If using a 787, press HOME, select TV & press ENTER, the channel list menu appears. With the highlight on the top of the list, use the < and > arrow keys to select from: TV, DTV, Favorite, or ALL. This lets your pick whether you want to see digital, analog, favorites with the "HEAR" symbol, or all stations.

THIBSRUS:
I think that there is a selection on the Panny that works much like the TV/VCR selection on a videotape recorder. Your machine is receiving and decoding digital stations, as you stated you can see them on the menu screen, but is not passing them through to your TV set for viewing. To use the Panny as a tuner for live TV shows, or actually, programs currently airing, you have to tune the TV to channel 3 or 4, or, if using the Red/White/Yellow connectors, the proper video input selection, AND turn the Panasonic on, and have it sending the programs it is receiving out on the antenna connection or the video/audio out (RWYellow) connections. It is really a matter of selecting, on the Panasonic, whether it passes through the antenna signals, or the digital signals that is is receiving.

You need to go into the menu and set the "av-2 out put" to DTV, that should solve the problem, remembering to connect the "in" scart on the recorder to AV-2 on the tv.If there is only 1 scart on the recorder it will be a 2 way connection, sending and recieving a signal.

use a scart lead connected between your digital receiver to your tv
