HI, I have a VRX630 and a VS735 player. When i use high volume, the bass generates a interference on the screen. It only happen with video, when I use radio, even with the screen interface On it doesn't occurs. Is it interference at AV cable?? Note: My VRX630 has a yellow input, i don't use the cca389 cable. PS: Sorry if I wrote something wrong.. I'm Brazilian and don't know english very well. Thanks Guys.
