I have sony bdp s300 tonight it began intermittent loss of HDMI signal. It comes and goes. Not the cable, just upgraded to the most recent software. No damage to the HDMI port. This one has me beat.
What brand of tv do you have?? Also what resolution does it display? 1080i, 720p,480i or 420p?some DVD's only use certain ones. U gotta make sure your TV can display the resolution from the DVD.
