my flatmate and i have been trying to hook up a laptop to the tv in the lounge which is working fine in the pioneer csx-c502 receiver. This works fine using a 3.5mm to duel-rca adapter and svideo to composite, until the power adapter is plugged in, and then the speakers start hissing. ive tried this on 3 different laptops (different brands as well). ive tried separating the power cable from the rest to no success. any suggestions on how to prevent this occurring?
I'm afraid you're probably stuck with it mate - it'll be coming from the laptop itself once you plug the adapter in.
damm, wouldnt have thought it to be the laptop since i dont have a problem when its connected to my monitor (via dvi), headphones and pluged into the powerpoint
That is not interference, that is the ground differential effect. To fix it, get a "ground loop isolator".
