If all your other VHS tapes are playing well, except for one, then I'd expect that your "bad" tape has "sticky shed" syndrome, or it's missing oxide from being played too much. Other causes could be that the control track on the tape is damaged; or that the "bad" tape was recorded on an out-of-alignment VCR.

First, look closely at the audio/control head while the tape is playing (located just to the left of the rubber pinch roller) If the tape shows ripples at the very lower edge, then somehow the control track has been damaged.

"Sticky shed" problems often can be temporarily cured by baking the tape in a tape dehydrator.

Unfortunately most other problems are very hard to repair. Often the "bad" tape has been recorded on an out-of-alignment VCR. This sometimes happens when someone has a jammed tape. They fight with the mechanism to get it out, and in the process, some of the tape guides get twisted. After that, they continue recording, and as you'd expect, the tapes recorded on that "damaged" VCR will play back okay as long as they use the same VCR. However, every other correctly aligned VCR will exhibit playback problems with that tape. The only way to watch that "bad tape" would be to diddle around with the alignment on a cheap VCR, trying to get it to match the playback of the "bad tape".

Transferring tapes isn't as easy as most people think!

This is a common question that comes up quite often. The name “Panasonic AG-1980 “and “Panasonic AG-1980P” are one and the same! The front of the VCR has “Panasonic AG1980” stenciled on it, while the serial number label on the back says “Panasonic AG1980P”. This is the same on all Panasonic AG1980s. The added “P” also appears above the serial number sticker on all Panasonic VCRs from that era. ie. Panasonic AG-1330P.

Regardless of what people say, the end-all, and final determining factor in how well a videotape plays back, rests with the condition of the video heads. Worn video heads won't playback EP (slow speed) VHS tapes properly. Hi-Fi sound playback will be hard to achive, and the video picture just won't track correctly. (You will, however, in most cases, still be able to play SP (standard speed) VHS tapes).

All of the "sale" refurbished Panasonic AG1980s that we sell, have high-quality, replacement video heads installed. Our video heads are "near-to-new",  as measured on our waveform monitor. We currently stock over 50 video heads, and when we're rebuilding AG1980s, we only select the very best heads to install in our "sale" refurbished AG1980s. You can rest assured that you're getting the best possible playback when you purchase a TGrant Photo restored Panasonic AG-1980.

Note: All AG-1980s sent in to us for repair retain your original video heads. If, after testing, we determine that your heads are in poor condition, we'll call you to see if you want better condition heads installed.

There's two schools of thought regarding auto video head cleaners. Take a moment to read my take on it! ~ Tom

Should I use my VCRs  auto-head cleaner?

Maintaining a good, clean capstan-pinch roller combination is very important in playing back a good, steady picture. Take a few minutes to read my new article:
