My mother recently purchased a Toshiba 50-something inch 16:9 HDTV and one of those Sony "HT in a box" systems. I went to try and help her set everything up, but I'm having trouble trying to activate the progressive scan mode. We're using component video cables in a direct link from the TV to the DVD player. The DVD player has a switch on the back that can be set to "interlace" or "selctable". When I set it on selectable and then acess the DVD setup menu, there is an output option for "interlace" or "progressive". When I select progressive the entire monitor goes black. Nothing shows up, not even the DVD setup menu, just total darkness. I have to physically set the switch back to "interlace" to get the picture back. I don't own an HDTV and don't know much about how this stuff works, but what am I doing wrong?
