I've had a Panasonic 4-Head OmniVision VHS VCR for a few years. A few days ago, I found that when I try to use the remote, the display on the VCR shows the message 7-U and then does nothing. I can operate the VCR manually, so I still have the use of it. I can't find the manual so I don't know what 7-U signifies and I don't want to spend money on batteries unless I know that is really the problem. I've tried replacing the batteries with others of unknown age and history that I've found lying around the apartment and they have no effect. Maybe dropping the remote once too often is the source of the problem.
Anyway, just in case the remote is dead, even though I doubt it, does that mean I have to replace the entire VCR?
