I have an LG LCD TV (LG 37LG5000 37IN). I also have an older DVD Home Theatre System (SONY DAV-DZ100). It seems that the surround system works well with DVDs but I cannot get the sound to work with DIGITAL...


It works fine if you plug the surround system SCART lead into the AV2 input. I believe this is a 'smart' scart plug (same as SONY but it is not mentioned as in the literature). The AV1 is only good for inputs NOT outputs as well.

Tv-- signal strength normal but signal on all channels "blipping" down intermittently causing freezing of picture. Have replaced aerial with high gain antennae together with aerial cable and...


When ever the picture freezes intermittendly the problem is usually poor connection on the signal line (antenna or connection on tv) or poor reception. Could be the tuner if the tv has one.To eliminate the tuner possibility try anther tv set if possible.
If you still cannot figure out the problem,let me know what kind of set up you have connected to your tv set.
Do you have a satellite or cable box and if you have splitters.

I don't know how to connect the cables from my VCR & DVD to the LG HD Plasma TV. "No Signal" appears on the screen when I try.


So, does it always say 'No Signal' or does it come up when you get it connected? If they are off when you are connecting them, that sounds okay; you'd get a signal when you turned the DVD player on (and told the TV to pay attention there.)

You might need to get an upconverting DVD or SVHS machine (since those are not normally HD) to get the TV to tolerate the signal, but the TV menus might let you activate that too. Why not look up the HD Plasma TV manual online according to the model number? If it turns out to be a monitor rather than a TV; of course, that is why it would not display those signals...you would need a separate tuner or signal selector box for that.

What's that bumpersticker abbreviation... ROFLMAORTFMYGDSOB? Good luck checking those out, since you get to decide which box renders the SD signal into HD....
