I bought this set three weeks ago and thought I had tested it all. However I have found a strange problem when using the SVHS3/Ext3 socket. When I first tried it using an LG DVD player connected with an S-Video lead it seemed fine - this lead still works. However I have recently tried an X-box using an S-Video lead, a gamecube using the 3 phonos and a camcorder using the 3 phonos. All produce an unwatchable picture ( almost black, sometimes just lines jumping across it ) and distorted sound. I have tried all three items on another TV with the same leads - all fine. So I went back to the DVD player and tried its S-Video lead again - perfect picture! However when I unplugged it and tried to use the X-box and Sky digibox using the RGB scart, both pictures were overly blue. Switching off the TV cured the blue problem. I'm assuming the Ext3/SVHS3 socket is faulty and have reported it to QED. They want to check with Philips on Monday to see if it can be fixed over the phone, which I doubt, before arranging for an engineer to come out and look at it. Anyone out there with a Philips 6515 have any help on this please?
