connecting SV to multiple tvs

i am trying to connect my SV box to a second tv. the picture on the second tv is clear but the sound is just a hiss. is the problem to do with wiring or just the box?

 

I guess your connecting the second TV through RF out? Try another coax cable maybe.

 

I am not near a stb so I am not sure of which menu but I think its in user setup. Change to PAL/I. PAL/G is used in netherlands and germany and they use a different audio channel.

 

thanks alot. my parents are now happy
