Vo-9800 I'm working on a sony vo-9800, the problem is when i try to play back, the tape plays excessively fast. I've adjusted the capstan and drum free speeds but the tape still runs extremely fast. what can be the problem, and how do i fix it?

This problem is often caused by the tape bunching up underneath the flap. Press down on the small release button on the side of the VCR machine and then lift up on the flap.

likely something has wrapped around the drive capstan, that would make tapes play faster. Forward and reverse are likely belt issues.

You may have some broken tape wrapped around the capstan. The capstan is the small silver post that rotates when the tape is playing. A rubber roller presses the tape against the capstan. This silver post needs to be just that - silver. If it has any brown tape or goop on it, clean off the tape or goop with a small knife. Then follow up with nail polish remover [acetone]. Don't use alcohol because that will harden the rubber roller over time.

Hi, the casette deck has a mechanical system (servo-driver) most of the problems that happen when in your case, plays song so fast is that you look at the pinch roller. The pinch roller is a rubberized free spinning wheel typically used to press magnetic tape against a capstan shaft in order to create friction necessary to drive the tape along the magnetic heads with a normal tape speed if the pinch roller brakes, get lost from his place or got dirty then you get this fast sounds play, check the pinch roller if still good in his place or clean his rubber with alcohol, then the problem should be fixed.

go look at fixya manuals on manual dir

Sounds like the pinch roller isn't engaging. The pinch roller is a black rubber wheel that presses against a silver post (capstan) the tape is held between them. With the door open and no tape press play. The roller and capstan should touch. If it recently ate a tape there could be some tape on the capstan that also will cause it to run fast.

Way to go. Usually if you use anisotropic Alcohol with a few Q-tips works well I've found.
Try cleaning the other tap path items like the capstan that the pinch roller get's pushed up to also with this Alcohol. The cleaner the better the tape goes through. Much better picture.

When a VCR eats a tape, it can be cause by a couple things.

1. There is a rubber wheel called a "pincher wheel" that compresses the tape against the "capstan". The capstan is a shiny metal spindle connected to a motor. The pincher wheel can become worn and/or dirty (slick) from the oxide coating off of the tape. You can try cleaning the pincher wheel and capstan with alcohol or try using a re-grip solution on the pincher wheel. Last thing to do is replace the pincher wheel. Look to see that the pincher wheel is doing its job by pulling the tape through. The pincher wheel & capstan are not used during a fast forward or fast rewind, so if your tape is getting caught during the FF or RW and not Play, it's probably not related to capstan & pincher wheel.

2. There is a small tire wheel called an idler tire. This tire pivots between the sending and pickup reels of the player. Its also used during fast forward & rewind as well as play. If the tire is worn, the tape won't be wound up as fast on the take-up reel as the sending reel during play. This means more tape is coming out of the cassette than can be wound up on the takeup reel. You can try using a re-grip solution on the idler tire or replace it.

3. There's also a brake pad that is designed to grab and stop the tape wheels from spinning when you hit stop. If those pads are worn, the wheels will not stop fast enough and the tape will continue to feed (spool) out of the cassette and not be taken up by the other wheel.

So when when you hit eject, the excess tape that should have been wound up tight in the cassette before the eject sequence, is getting caught inside the player.

Let me know if I can be of further assistance to you.

Good luck!

No, this U-Matic VO-9800p ist a PAL Model, it only Records in SP and High Band Mode. If a SP Tape is inserted, it Records SPMode, otherwise High Band. Low Band Mode is only for Playback !
(Low Band Playback is of very poor Quality, do not use this for Digital DVD Captureing )
