Hello all, I could really do with some help. I've just bought a Sony AV Receiver, and I'm having problems already. Simply, I cannot get an Image/Sound from my Freeview HD Box (Technika). I've tried my PS3, and that works fine, but I've tried changing every setting in on the Technika box to no avail. I am using the same cables as the PS3, literally just swapping them over, and making sure the cable goes from the 'Game' port to the 'Cable/TV' port on the receiver (Although I have tried all ports incase any are dodgy). The receiver can see that there is a HDMI cable in, because it says so on the front screen. When I switch the Technika box on / plug it in, the TV flashes green and there is a funny periodic buzz from the speakers. Connecting the Technika directly to the TV is fine, as I have been doing so for months. Any clues? Thank you!
