Then this week the Tivo can't even get a signal on channel 690 so all i get is black. of course every other channel works fine. i rebooted, power-cycled the tivo and still the same problem. I contacted FIOS and they tested the signal from their end and could not resolve the problem. They are sending a new cable card in the mail however. Anyone have any ideas why one channel won't work? FIOS said no one in my viewing area was complaining about ch 690....
Thanks in advance
check the ends of your coax and also look for kinks in the coax wire.
use tivo dvr diag to check the frequency. also check if there are lots of RS errors. See if channels with frequencies near this one also have trouble.
