Hello, Typically they use either 2 or 3. Your vcr might have a slide switch that will allow you to select either channel. You can usually find it by just switching channels. If it still looks like your not connecting, make sure cables, either coax or rca, are pushed in securely. You can always troubleshoot by trying other vcr or dvd player and also try on other tv. Hope this Helps
