Usually when there is a pink screen, it's an indication that the source sending the signal to the television isn't set to send the signal through HDMI. It may be set to send the video component. Try switching the output of the source to HDMI Out and let me know.
I have a new Samsung 630 version LCD tv. When I plug the HDMI cable into the HDMI 1 port, the screen turns pink. Also, when Comcast guy plugged in his HDMI cable, it made a funny noise on and off. When it's in HDMI port 2 it's fine. Should I return the TV or is there something to fix this? I am using a Phillips $80 HDMI cord. Please help if you can.
