I have an eight year old GE TV, and for some reason, it will only accept signal from coax cable. it simply will not process from s-video or the three RCA jacks. I do not currently have a manual for it. I am tring to put in a 4-way splitter/device box (SAT, DVD, VIDEO,game), but it won't work without s-vid or rca. Conversely, I tried to run everything through my Sony DE 945, but I am having the same problem...the reciever won't process signal from S-vid or RCA from the sat. reciever, and wont send it to the TV. I admit, i am a newb, so any help is much appreciated! Thanks!
