Hello
Has anyone experienced faint diagonal lines in TV and PC Tuner image after splitting an RCA output from one video source?
I have a 7 meter RCA video cable from a solid metal RCA Y adapter fed under the house to my new TV tuner card (cheap TV2000 XP Expert one but very impressive results) from my Cable TV box's output. Whenever I plug in the RCA cable (to the PC and the TV) very faint close diagonal lines appear on the TV and on the PC's input image.
I have seperated the cables under the house to avoid magnetic fields but the lines still show. The cable was originally 16 meters but I reduced it's length to 7 meters and re-soldered the plugs.
I am guessing it has something to do with an Earth Loop ( http://www1.jaycar.com.au/images_uploaded/humloop.pdf ) that has now been introduced between the multiple devices. Is there anyway to eliminate or reduce the inteference without eliminating the earth wire?
Ideas?
