I recently replaced my old (2003) surround system (Non HDMI)....with a new (Cheap but much better) Yamaha RX-V377 surround amp (Finally, a real Amp!

)...But found out that I have to start my HDTV,and then AMP (DISH receiver usually always on) in the proper sequence,..so they can can check/talk to each other b-4 they decide if they want to give me video or not!..Just an observation, But found out this is becoming a common thing if you connect equipment using the HDMI connections!...Sometimes my TV only shows a PINK screen after starting it all up, the fix is to shut down Surround Amp and TV, Then Re-Start,And everything is OK!
