Page 1 of Panasonic DMRE50 HELP PLEASE

Can anyone help me please.
I have a Panny E50 and am very pleased with it.
It is set up with a Sky digibox via rgb scart in and out and when watching dvd`s I watch via AV1. I record via AV2 in rgb.

My problem is this: if I set the channel on the recorder to AV1, which is the playback channel, then switch off my skybox, I get a steadily increasing hissing sound and the screen seems to turn a green/black colour, with the channel display seeming to dissolve.

I had a hard time describing this problem to tthe staff at the shop and they told me to check the leads, which I had already done. Any ideas anyone? All advice gratefully received!!!!!!!!

Digibox is the only external input? ie. no RF ariel lead connected to the E50. So when you switch off the digibox there is absolutely no input to the E50 apart from the general noise the RF socket will pick up. What do you expect to see in these circumstances or is there something you forgot to mention such as an ariel being connected?

Yes, I have an RF ariel lead connected, plus two scart leads, one to the TV and one to the digibox, both via RGB. I also have an ariel connected because when I disconnected it I got no reception. Is it wrong to have the RF lead and ariel connected if you also have the two scart connections in use? Thanks in advance.

It`s feedback via the SCART, but let me get this right in my own head. AV1 on the DVD recorder is connected to the TV? Therefore The DVD recorder is watching whatever the TV is displaying, which is a blank AV channel when the SKY box is in standby, meaning that the DVD recorder is then watching the blank signal which it is outputting to the TV and hence causing feedback as it loops audio and video to the TV and back again.
Best advice in this case is to make sure the SKY box is connected to AV2 on the DVD recorder and leave the recorder on AV2. The TV will then accept RGB from both DVD recorder and SKY box while allowing you to watch DVD playback in RGB aswell :)
