I have a one year old Sony KP-57WS520 which has an HDMI input. I've tried several different HDMI cords and upscaling DVD players and when connected to my TV's HDMI input, the picture drops out quite frequently. The HDMI connection piece feels slightly lose when I move it, but not really anymore than you'd expect. Is there anything I can do to fix this matter? Someone on another forum told me to try different cables as maybe the male connectors aren't large enough for the female connection. But, I've tried several cables. Also the cable seems to be connected pretty good if you know what I mean. It's not falling out of the socket. But, again, maybe the connectors are touching something inside my TV input. I would like to avoid having a service person out since I don't trust what he might do (too many horror stories!).
