I have a 500 dp plus dish, with 2 cables going to my 625 receiver, I installed a separator switch so I could get rid of one cable but with switch installed only one of my tv's get a signal, what am I doing wrong!
also make sure the tuner 1 port of the separator goes to tuner 1 on the receiver. although like the above post's say you probably only have a dp lnb not a dpp.
We really can't answer the question without knowing how the other TV is connected and what other changes you made. Is it a direct line from receiver to TV? Is the TV2 output backfed onto the satellite line and if so can you provide a diagram showing the diplexer and the Separator?
