enjoy Tosh 62HM84 for months, really nice PQ. didn't have HDMI gear until now. so try it to see how much improvement over component. however, I can't make it works! tried 2 HDMI DVD sources (Sharp HRD300 and LG DF9921N). TV shows 'doesn't recognize such device'? 4m long HDMI cable is ATC certified which is tested w/o problem. players are tested ok on another HDMI display. have tried Tosh on first, then player on later -- > NG. then try player on first, then Tosh on later -- > still NG. what's wrong? how to solve such problem? need you guys' help! tks.
