Re: Ghost Channels over TV
I have had this before when feeding the dvd into the tv via scart - the answer was to put the tv onto a blank channel first before starting up the dvd player.

Re: Ghost Channels over TV
Why does this happen? I've always wondered that!

Re: Ghost Channels over TV
It's probably due to poor screening between the different audio sections in the TV so that you get pickup between them - that and the fact that our ears are incredibly sensitive at low levels.

Re: Ghost Channels over TV
It could be a loose connection somewhere. Years ago I used to have a reel to reel tape recorder which if I plugged a cable from this to an external source and the cable was not fully pushed home on the tape recorder I used to get ITV sound coming out of the recorder.

TV has two scart socket.....one come direct from a VCR and the other is cable box to DVDR to TV.
Really strange..............if I press play it seems to have to problem. If I switch to channel 8 then press play it's ok.
Any more ideas welcome

Re: Ghost Channels over TV
Kind of sorted this.............. just move the VCR to AV1 (was AV2) and the cable/DVDR to AV2 (was AV1) and it works OK !
Any ideas why

Re: Ghost Channels over TV
Found a way around this is to use a scart block that has input/output on the switch to ensure that your signal is one way only

Re: Ghost Channels over TV
mmm...
Although the video signals in a scart lead can go one way only, there are two pairs of audio signals. They are wired in a cross-over fashion and allow, for whatever reason, stereo audio to be sent in both directions at the same time (a weird standard is scart  ). It could be that there is poor screening in the scart cable and you are getting pickup between the audio leads. Alternatively, something in the DVD is getting pickup or not disconnecting properly.
