By my VCR Panasonic NV-FS100 many noise bars sometimes appears on the
screen
in play mode... What could it be? Tape tension?
Thank you!

There are known faults on this machine that cause these symptoms, but it
could just be clogged video heads.

But if you don't know anything about VCRs, then take it to a qualified
technician for an estimate.
