TV screwed

Hi. I Recently moved my T.V. to a different part or the room. I used to hook up my T.V. through a VCR so the cable television went wall/VCR/TV. It worked perfectly! I moved it all to the other side of the room. I now have problems and can only recieve the first 13 channels. What do I do? My VCR is a GoldStar C220M and I have a Toshiba Blackstripe T.V. Thank You in advance!
