Hi Guys. Does anybody know why the screen goes into standby, once i switch off dvd player? Just connected new player with HDMI cable. Played movie, stopped player & switched it to standby. Screen & media box went into standby, turned back on remote, media box came on but not the screen, which started flashing. Had too reset on & off switch on screen, to get any picture. Never happened before. All connections were as before, with other player. Any suggestions on why this is happening?
