let me get this right.
you have two cables hooked up from tv to receiver.
are they rca cables?
typically you would use white and red though for audio. are they connected to a white and red colored port? specifically are they connected to the tv outputs and receiver inputs?
yellow is typically video and if you are using the tv tuner (which it seems that you are?) i dont know why you are using yellow as a tv output.
----------------------
what i need from you is a list of every single device you plan to use as an input to your television and receiver such as a dvd player, computer, ps3, etcetera. list all input devices. it would be helpful if you list what output ports they have as well.
i would also like you to list all input and output ports on your television. at a bare minimum you can give a model number or give us the online link to the manual.
this will help us tell you how everything in whole should be hooked up.
for reference this is the back of the vsx-43 which we will be needing later once you get done listing all devices and getting back to us.
-----------------------
to be perfectly honest i've never used zone 2 on my receiver.
have you read the manual at all about setting up multi zone?
also here is a link which provides a little more insight on multi zone and receivers.
