I have a NEC VT-45 projector and a cables to go (TigerDirect) 75 foot cable for HDTV, running through my ceiling down the wall and to the receiver......the Red, Blue and Green RCA connectors are giving me trouble.... wiggle them and the pic is fine....more some more and it looses colour... Is it possible to cut and recrimp with new connectors? I've recrimp lots of ends, but in this instance, is it just a ground and the main wire??
