Problem-"Tuner Failed"

[mchris]

I have 2 dishes and 3 lnbs- Hotbird 13E, Eutelsat 16E and Hellas 39E. When changing from channels of one sat to channels of another sat i am getting the error "Tuner Failed". I noticed that the signal strength is falling from 8-9 db to 0.01-0.03 db. After few minutes i am getting another error which says that there is no data on this transponder or something like that (I am not home at the moment).
I am the using the latest GP 3.2.

Any solution????
