I have a sanyo dvw-7200 vcr-dvd comdo that isnt very old. the problem is that when i try to record it acts as though the tracking is off. the picture jiters, has white and black lines in it and also the color comes and goes.it plays back videoes just fine and the tracking adjustment works just fine.it started doing this just a little while ago and i noticed if i fast forwarded the tape about a little ways in it wouldnt do this but now that doesnt work.need help thank you.
It sounds like the back tension is off on the unit. the back tension is controled by a small band attached to a copper or metal strip and that ia wraped around the supply reel and is adjust by an arm that swings out and contacts the tape during record or playback and keeps a steady tension on the tape. If the back tension band breaks or wears out you will get a picture that looks like the tracking is off or bad or dirty video heads. Most likly you do not have a backtension gauge and it certainly would not be fesable for you to purchace one as a good one cost about 100 bucks or so. A repair shop may beable to adjust it for you, But even their fee may be cost prohibitive. Good Luck PS please do not forget to rate this.
