Hi. I've got a problem with both VCRs in the house. Some months ago both just stopped being able to tune in channels from the aerial. As a result, it is impossible for them to record anything. The thing is, the signal goes through each VCR to get to each relevant tv, and the signal's absolutely fine on the tvs. Would anyone have any idea as to what might be happening and how I could fix it? It's driving me nuts. Thanks in advance for any replies.
