So here's my situation. I have a harmony 676, a Panny TH-42PX50U, a SA 8300HD and a Harmon Kardon AVR-240. Until about 2 months ago everything was running smoothly but then it seems as if over night this one problem crept into my happy little universe.

Whenever I use my activity button to 'Watch DVR' it turns on the TV, then the receiver and finally the cable box. The remote is still picking the correct input on the tv because I see it shuffling through the options on the screen. However, after everthing is up and running I have sound but no picture on the screen. The only way I can get the picture to come on is by turning off the TV and then turning it back on (with the TV remote).

Any suggestions would be MOST appreciated.

Thanks in advance.
