I recently got a HDMI 3x1 switcher so I could connect both my HD satelite, and my Panasonic S77S DVD player, to my Panasonic ae900 projector. My satelite works fine, but I get a weird code on my DVD player screen; U-70 and no signal. I tried changing cables etc.. it seems as though there is some feedback going from the switcher to the s77s DVD player ? However this doesn't seem to bother the HD satellite reciever. I don't know the brand of the switcher, because after people telling me that I'm wasting $money buying super expensive Monster stuff, I went a cheaper route eBay. Still paid $118.00 for it though. Has anyone experienced anything like this ? Or know what these codes mean ? Or how I could find out ? Thanks to all. anyone recommend a good switcher ?
