Just got my 52EX700 today. Looks really good and I'm very happy with the set. I do have one question though. I have four video sources: Pioneer BDP-51 bluray, an Onkyo DV-SP1000 dvd player, a Panasonic DMR-EZ27 dvd-ram recorder and a Magnovox DVR recorder. I have a Classe SSP-600 processor without HDMI switching so I have all four sources running to a DIGI Media HDMI switcher (4 in 1 out) which in turn is connected to the HDMI 1 on my Sony TV. What is odd, though, is that the Magnavox and the Panasonic recorders pass video to my TV but when I select the Pioneer or the Onkyo on the HDMI switcher the TV says "no signal" detected. I can run a HDMI cable direct from either the Pioneer or the Onkyo to the TV and all is fine. When I hook them back to the switcher no video. Everything worked fine on my old KDF-E42A10 so I'm a tab perplexed. The HDMI switcher is model number HSA-401. Any ideas? Thanks.
