What happened to KGO-DT- San Francisco Bay Area

Archived from groups: alt.tv.tech.hdtv (More info?)

For the last few days I have not been able see any video from KGO-DT. I
get plenty of signal on channel 24 (007-1 and 007-2), but no picture.
Also
it locks up my Dish 6000 receiver, and won't allow me to change the
channel until the reciever, after about 10 seconds, removes the
channel(24) from the list of mapped channels.

Anyone have a clue as to what might be going on? I did try to contact the
station for an answer but no response.
