Problem started over the weekend with my 434HDE. When turning on the equipment i.e. av amp, sky+ box and plasma media box the image when it appears is zoomed in or clipped. So much so that you can just pick out the sky banner at the bottom of the screen. If I then cycle through the teletext button (three presses) and return to full screen the problem resets. Obvious I now don't want to cycle through teletext every time I turn on. The only feed to the media box is via scart from the av amp. I have connected directly from the sky+ box but does the same thing. Also if you change from AV1 to AV2 and the back to AV1 again the image again becomes clipped. Contacted Pioneer via email but no answer can anyone help please?
