I have 2 new TV's in the house. One in the living room, one in the bedroom. With the old ones, they were in-sync, like stereo when you went from one room to the other. I bought 2 new flat screens and if I have them both on, they are not in-sync, drives me crazy.

This would be down to how the signal is received.
Are they both the same TV or are there differences ?

Also, do you have a cable/satellite box on both/either of them? And are they the same boxes?

Living room is a Sanyo. Brd. Is a Philips. I have cable, wired into the wall, plugged into each TV, no box.
