Hi, I've just bought the Panasonic TH-42PA30 and I'm having trouble with the setting it upi with a sky digi box. I'm currently using the 3 scarts connections on the back like this.- AV1- Sky digi box. AV2- DVD player. AV4- Satelite set top box. The satelite box is also 'looped through'd' to the sky box. The trouble I'm having is the screen seems to flash red in the background when using the sky box. The satelite box and DVD are fine. I've not changed any settings in the sky box, but have tried to play around with the plasma settings with no joy. I'm pretty new to this so talk to me like I'm 5 years old.! Thanks for the help.
