Re: vo-9800

Are you playing back a tape which has the correct TV system? If it isn't, it will playback incorrectly.

The audio/ctl head may be dirty or defective.  try cleaning it; if it can't read the ctl track, the playback will be fast as you describe.

This sounds like the belts on the take-up pinch wheel if it's streached then it's going to be fast if you can find all belts that take tape to drum and read heads then check each one if streached replace if all fails when replaced belts then it needs repair. hope this works

Toshiba DVR-670 VHS VCR plays then stops

Something is causing the electronics to think that the mechanism is faulty. It will shut down the system if it thinks that, to prevent tape damage. You need to check for any kind of damage to the mechanism. I know you say you have looked, but check again. If you don't find anything. I would replace the VCR mode switch. You might get away with a spray of Servisol Video 40 on it, but if you can replace it. You will need the service manual for that. As they are tricky to set up.

What is an error 20 message on a Sony VO 9850?

Remove the bottom cover and flip the circuit board out of the way.
Check to see that the capstan drive belt is not loose or broken.
Also, open the top cover and check the drive belt for the cassette transport.

Loads tape then stops - won't play rewind 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.

Tape Problem

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!

I'm not sure how old your unit is but over time, the rubber parts in a VCR become cracked, glazed and begin to slip.

There is a rubber wheel about the diameter of a nickel that is called the pincher wheel and does exactly what its called.

It pinches or compresses the tape against a shiny metal spindle called a capstan. The capstan spindle is connected to a motor. The pincher wheel rests against the turning capstan with the tape in between the wheel and capstan.

The pincher wheel can become glazed and coated with a brown oxide that has worn off of the tape. This causes the tape to slip and it can spool out into the VCR.

There is another wheel called an idler tire. It lays flat and pivots between the sending reel and pickup reel. Its used during play, fast forward & rewind. This wheel too can become glazed and worn causing slipping. If your unit won't play, fast forward or rewind, most likely the idler tire is the culprit.

There are also belts that can also become glazed and worn. These belts are used along with motors in the tape load/eject mechanism and capstan drive. If the belts slip, the tape may not load or eject properly and the capstan might not be turning properly.

When I owned my repair shop, one solution was we to remove the belts and/or tires and apply a re-grip solution on the rubber with a cotton swab, while roughly rubbing the the entire rubber surface back & forth with the swab. The re-grip solution actually eats away the top surface of the rubber leaving the rubber surface course and causing it to grip better.

Another solution was to just replace all of the rubber tires and belts. These parts including the re-grip solution may be ordered through

Please let me know if I may be of further assistance to you.

Good luck!

Rewind or fast forward

Though not familiar with this model, VCRs of all sorts have an idler mechanism which drives the supply and takeup spindles. Either the idler is somehow defective and slipping, and, assuming this idler is belt driven, the belt may be slipping just enough to cause a no Rew/FFW condition. If you had access to a test tape jig (a clear dummy tape, which allows a tech to view what is happening in the area normally obscured by the loaded tape), this might give a clue as to what is happening. On alot of machines, a problem with Rew/FFW would also mean a tape takeup problem in standard play, result in tape spilling out inside the machine. Sensors would catch this condition and go into a error mode, as yours is doing. One other thing which might be happening here, is the pinch roller not being disengaged from the capstan in the Rew/FFW modes. I think this is where I'd look first, and you can probably see if such is happening just by pulling the cover off the VCR. The pinch roller is just to the right of the rotating video head. In the play and forward/rev search modes it will press the tape up against the capstan (a rotating shaft). When in Rew/FFW, the pinch roller should be pulled back from the capstan, maybe 1/4 inch or so. Whatever the case, repair will likely take someone tech savvy. Costs might not be economically justified, with the low-cost, disposable rigs sold in the last 10+ years.

The unit will fast forward and rewind, but won't play

This is a problem with the process called 'tape loading' - pulling the tape loop out of the cassette and wrapping it around the spinning video drum, engaging the capstan and pinch roller and reel rotation. Check all the belts above and below the deck. Belts can appear to be firm but if they do not return immediately to their relaxed length when you stretch them 25%, they will need to be replaced. With the cover off, observe the behavior when you hit play. (You may need to put a piece of cardboard over the cassette to block external light from interfering with the start/end tape sensors). Assuming this is a basic VCR (no instant start features), you should see: 1. The video head drum begins to spin. 2. the roller guides move smoothly on the tracks, wind the tape around the drum, and stop snuggly pressed against the 'V-stopper' at the end of the tracks. 3. The pinch roller moves into position and presses the tape against the capstan. 4. The tape begins to move and is wound up by the takeup reel. 5. The picture and sound appear on the TV. With a 'rapid or quick start' (or it may be called something else) transport, the tape moves to a half-loaded position when the cassette is inserted. This is at an intermediate position partially pulled out of the cassette but not wrapped around the drum. On VCRs with a real-time counter and/or index search capabilities, the tape will be in contact with the control head. With an 'instant start' transport, the tape will fully load around the spinning drum when the cassette is inserted but the capstan will not engage and no tension will be applied to the tape until you press PLAY or REC. (After about 5 minutes, the drum will stop and it may unload to the half loaded or unloaded position.) Note that for VCRs with a real-time counter and/or index search capabilities, the tape must be in contact with the control head (but not the video heads) for all relevant modes. These VCRs (which include many modern units) must therefore pull the tape at least partly out of the cassette. In all cases, the completion of the sequence results in approximately the same mechanical configuration during PLAY. Several likely possibilities when it shuts down: 1. Everything occurs as above, picture and sound appear for a few seconds, but then the VCR unloads the tape, ejects the cassette, goes into REW mode, stops, or shuts off. Two common causes: The takeup reel does not turn and tape spills into the machine. This is sensed by the microcontroller which aborts record or play and attempts to save your valuable cassette. Most likely cause: old/dirty idler tire. As a test, turn the idler tire inside-out. The fresh surface will now work well enough to confirm this diagnosis and will continue working long enough for your replacement idler tire to arrive. See the section: "General guide to VCR cleaning and rubber parts replacement". The takeup reel is turning properly but
