Only can see 1080i Video on my TH-37PX25

Hello,


I am totally at the end of my rope. Last night my Panisonic TH-37PX25 got in to a strange "funk." I was watching a football game in HD and after it was over, my wife switched the input to where I have our DirecTV TiVo attached. The video from my DirecTV unit would not display. I can get audio, but no video. So I switched to the input for the DVD player, same story. When I switched to the antenna input, the only video I can get the channels broadcasting in High Def. The other channels are all audio only. I even plugged in an external HD set top I have for another TV, same story, only the HD channels show video.


It seems like the TV will only display video in 1080i. I have tried everything I can think of...going through all the setup menus, plugging in another device into one of the componet inputs, upgrading the firmware, with no success.


I wanted to post this to see if any of you have any ideas before log a service call. This is driving me crazy.


Thanks,


Doug Knight
