I have recently started having some issues with the HDMI connection on my Samsung DLP...hl-5067w. Sometimes, when I turn on the TV and either my digital cable box or upconvert oppo dvd player, which are both hooked up through my HDMI, it will come on for anywhere from 10-20 seconds then go to a blank green screen, all snow or bounce back between the 2. I initially thought it was my cable box because shutting it down and unplugging the HDMI cable/reinserting it would take care of it. However, I got the DVD player and hooked it up the other day and it has happened a couple times with it as well. What could be causing this?? any help would be appreciated....oh, all the other inputs work fine. I have my 360 hooked up through component and a dvd recorder through AV/composite.
