Hi, Sounds like a mechanical problem in the tape path which can be anything from the pinch roller, take up spool, foreign object (such as splicing tape lodged somewhere), brake or others. An indicator would be stretch tape. One way to check if the tape is being stretch is to rewind partially one of the tapes you have tried, eject it and open the flap/cover of the cartridge. There is a stub on one of the side of the tape that you have to push to open it and see the actual tape. Stretching if any would be clearly visible. Am afraid that you would need the services of a qualified technician for the actual repair not unless you are familiar with video tape mechanism. On the video head, offhand, I doubt if it needs replacement.Of course an on site technician would be in a far better position to diagnose it for you. Hope this be of some help and pls post again how things turn up. Good luck and kind regards.
