After going through Tivo support they concluded that a new unit was needed. I received a brand new 140 unit and hooked it up. I was happy with the first few tests proving it worked changing channels from Sat to a channels above analog cable 46. As I got into further testing the unit started the same bad behavior as the previous unit. This it not a signal quality issue as I have removed all splitters and have a 15db Electroline drop amp increasing signal strength from the cable input in the garage. Interesting behavior I have seen that does not make sense.
Using remote channel down the Tivo changes channels from sat channel 101 to analog channel 82 (golf channel on analog) I get blue screen. Channel back up to 101 no problem, channel back down to 82 and the channel shows up no blue screen.
If I now change from sat to 54 (analog) the channel shows up sometimes! Sitting here testing shows it makes no rhyme or reason.
This is a most frustrating problem.
