No channell 10

[define]

Hello I am hopeful someone can help, I have just set up my tivo and all ways going great then channel 10 went down followed by onehd and sd I did a rescan then a reboot then a start setup again but it has all ended bad now It doesnt even pickup the channels at all. I have tried entering the frequency manually I belive its the 219. one but it says nothing found there.

My antenna is a new digital setup with new cable also. We even have an amplifier plugged in. All other channels are showing approx 90% signal strength.

If it helps I am in Mandurah WA and had no issue picking up these channels with a standard STB that the tivo is replacing

HELP PLZ

P.S it seems my volume button does nothing also
