What happened! I went out of town last Wednesday and when I came back today my 622 went nuts on me! No video or audio through HDMI. Had to hookup component and toslink. Hard reset resolves video problem to HDMI (sometimes). Going into Diagnostics, Analysis, HDMI Test and doing a reset HDMI resolves video problem again (sometimes, but usually only once after a hard reboot). Changing resolution from 720p to 1080i and back, etc. does nothing. My TV supports both of them regardless. In the HDMI Test screen, everything is greyed out except Disp Info. When I scroll through Info 1 and Info 2 at the bottom it displays "ERR: formatted_edid: -248". NOTHING I can do restores audio through HDMI. I've been using toslink since I discovered this bug. Samsung 40" LCD HDTV I have other HDMI devices that work fine and swapped cables, tv inputs, etc. so I have isolated the problem to the 622 itself.
