I recently replaced my mother's dvd/vcr player with a Sony blu-ray player for her Samsung LNS4095D. Although the display identified the title of the blu-ray disc, no signal was shown on the screen when selecting play. The TV does run DVDs from the player. I've changed the blu-ray player and the HDMI cable with no success. I'm therefore assuming there's a problem with the LNS4095D's ability to receive a signal via HDMI from a blu-ray player. Is anyone familiar with this problem, and if so is there a fix?
