hey guys I'm new to this site. I've recently taken a great love of hd equipment and services but am still very new to this stuff. I have has a 622 receiver hooked up to a Westinghouse LCD TV for several months without a problem. all of a sudden today the HDMI audio is gone but still available through stereo receiver and optical output. Then video goes out only on HDMI also. I called dish and they said is compatibility issue with some tvs. I do not understand if it's not compatible why it worked for so many months without a problem?? I've tried all the standard troubleshooting from resets to checking cables. will be replacing cable in a few minutes to see if that helps. The receiver also acted very strange with a green screen, press select to continue would not go away, after reset would not acquire signal until turned off and back on, and flipping randomly between press select to continue/black screen/video. I think the receiver may need replaced but dish says that i should just use component cables. I don't have any available ports because of other HD equipment. any suggestions on how to fix this would be great. (I apologize for the horrible english in this but i should have been sleeping hours ago) thanks
