Summary: I have a NEC 961 VCR, a NAD receiver (7144?), and a JVC television. I get interference when playing a HiFi movie while the cable TV is connected. If the cable TV is connected and I de-select HiFi, just playing the movie in linear stereo, the noise goes away. Details: 1. The bare problem. If I use *only* the VCR (no TV, no cable, no nothing, just my headphones into the VCR) and I play a HiFi movie, there is a faint noise that I can remove by resting my palm on the unit. 2. If I hook up the full system (VCR audio out into the NAD, video out into the TV, cable TV into the VCR, then the following apply: a) Noise in HiFi mode b) noise varies with the choice of movie, from faint to speaker-blasting c) noise varies with moving the tracking slide switch d) disappears when CATV connection is broken e) the VCR is ~10 feet from TV, and during testing was next to the NAD receiver on the floor. Any thoughts? Other than the inconvenience of having to unplug the cable TV once a week to play a Staurday night movie or two, the NEC unit is spectacular. The HiFi sound quality surpasses the linear stereo like CD's to vinyl. -- Jeff Percival ...!uwvax!uwmacc!jwp
