Hey fellas, Following up on my post last week it turns out the xbox lead was not the cause of the problem, this time I have definitley narrowed it down to the lights downstairs. Whenever they are turned on in the kitchen or living room, horizontal lines appear on the TV (its a CRT) and my AVi amp sends a small click/pop into the speakers. Probably not good for any of the hardware all around so I'd like to get it sorted, is this fixable with filters/mains conditioners or should I get an electrician around the take a look? Cheers, Dawson
