I had my PS2 hooked up to my new Toshiba 51H83 for about 3 days... I just got an HD box so I took the PS2 off and plugged in the component out from the box into the 2nd component input and could get no picture at all. After trying everything, I decided to switch the cables from the DVD player into the box and the HD displayed perfectly on the first input... so I then put those cables into the 2nd input and nothing!! It was working perfectly with the PS2 plugged into it, does anyone know what could have happened?? the DVD player doens't work plugged in there either... usually just all black like nothing is there, and sometimes I get squiggly lines.
