Query: RF connection doesn't work, bad technical support

This VCR have great feature for the price. It works enough well. It has to be used with RCA connection. RF connectors( in and out) are present. But output doesn't work and technical support of Samsung and repair centers are unable to get it work. Meaning you don't have a signal on the RF connector when you are playing a tape or selecting a specific channel.I should mention also Samsung technical support is very bad, they have big problem to understand this worldwide VCR. One technician even hang-up on me because it was close to the end of working day and didn't want to handle cases on this VCR...
