I have a Loewe Aconda 32 Widescreen TV connected up to a PACE Sky+ box. The Sky+ is connected to the TV by SCART. When Im watching a widescreen channel I get the TV switching between Widescreen and Zoom every couple of minutes. It tends to switch and then switch back perhaps a couple of times and then settle again. I have the Sky+ box set for 16:9 display and all SCART controls set on in the TV and SKY+ box. Can you suggest anything?
