Picture still looks great, but the PIP function is malfunctioning. When I try to use it all I get is a solid green screen unless I am trying to use the small window and in that case I get nothing. Audio is ok. Its like the video from the second video source is missing. Doesn't matter if its the on board tuner or the video inputs. Uhhh, this happened while in the service menu.None of the resets including unplugging from the AC supply brought it back.
