I see I did not get any response so it must be my question and not enough info. Anyway I can watch the local pbs channel only if I wait for about 10 sec pause the channel hit go back and picture comes on now if I switch to another channel and switch back to the PBS channel black screen again hit pause and go back picture again this is really annoying no other hd local does this only the pbs channel I have reset the receiver several times while being on the local PBS channel and when it goes through all of the rebooting and so on the picture does come on but just as soon as I switch and go back black screen again. Does anyone know what the problem might be?
