Hi all, Having swapped from the Sonix to a Sharp GA5, I've noticed that the Sharp is giving a buzzing sound from the speakers whenever (for example) the sky search & scan banner is on screen. The same effect happens on Sky news when the ticker bar is showing. Has anyone else experienced this? I'm using an IXOS scart cable connected in RGB mode from the sky box. I know the Sonix did not do this with exactly the same setup & cables I have now, so perhaps its a fault with the Sharp?
