Cassette Player Tape plays too fast. Cleaned audio heads/guides and replaced belts. Still plays too fast on both decks. Any adjustments/component checks I can do?

  • fredr Mar 08, 2008

    My belts needed to be replaced because the tapes would not eject. Now the tapes play too fast. Could I have threaded the belts wrong?



    Please help,

    Fred

I had this same issue with my stereo. I found that the rotation of the capstan was being blocked by a little glob of a red substance. I removed the substance and it allowed the capstan to rotate freely.

It might be a button error like the play button is making the fast forward button work.

Motor speed needs to be regulated by PWM. Reducing the current (with a resistor) actually lowers the torque - which, with a given load, does result in reduced speed - however, different length tapes (60min vs 90min), as well as different quality, and even current position in the tape, will change the load and hence the speed. You need to regulate the speed via PWM. It's sometimes done on a small board built into the motor, in which case you'd have a round hole into which you could insert an INSULATED screwdriver (tiny flathead wrapped most of the way in electrical tape works). It may be done on the main board, in which case you could find a pot conveniently labeled "motor speed", or perhaps "pulse width" or "pwm" or something to that effect. Find it, mark its current position just in case, and turn it to see if it gets the effect you're after. And there are some tape decks in the world with no speed adjust - they are designed with a specific speed motor and the sizes of the wheels and gears are calculated for that speed. Also there may be a mechanical fault/malfunction causing the speed problem. An initial check and thorough cleaning of the capstan and pinch roller should be done. If there is a buildup of tape oxide or a piece of a broken tape wrapped around the capstan, the tape travel will be too fast (do to the effective increase in capstan shaft diameter). If the pinch roller isn't fully engaging, the tape can be getting pulled onto the takeup spool at a speed faster than the capstan control. A different source of trouble might be a slip clutch (possibly an idler/clutch assembly)which is binding, or otherwise not functioning the way it should. Another type of motor doesn't have it's speed controlled by an internal or external voltage.. instead, the motor has an internal centrifugal speed controller. This type of motor can be found on older tape decks, and might not have been utilized more recently. Good luck

HOW TO REPLACE BELTS FISHER CR-W85

  1. Gather the necessary tools: You'll need a set of replacement belts, a small screwdriver or a similar tool for removing screws, and possibly a pair of tweezers or needle-nose pliers.
  2. Power off and unplug the cassette deck: Before you begin, ensure that the cassette deck is powered off and disconnected from any power source.
  3. Remove the outer cover: Most cassette decks have a protective cover that can be removed to access the internal components. Use a small screwdriver to remove the screws holding the cover in place. Keep the screws in a safe place, as you'll need them later.
  4. Locate the belts: Once the cover is removed, you should be able to see the internal mechanisms of the cassette deck, including the belts. The belts are typically made of rubber and are responsible for driving the tape transport mechanisms.
  5. Identify the belts to be replaced: Inspect the belts and identify which ones need replacement. In some
  6. Remove the old belts: Gently remove the old belts from their positions. You may need to use tweezers or needle-nose pliers to grasp and pull the belts off the pulleys. Take note of how the belts are positioned before removing them so that you can install the new belts correctly.
  7. Install the new belts: Take the new belts and thread them around the appropriate pulleys and drive wheels. Refer to any service documentation or diagrams available for guidance if needed. Ensure that the belts are properly seated and aligned.
  8. Test the belt tension: Once the new belts are installed, check their tension. They should be tight enough to drive the tape transport mechanisms without slipping but not so tight as to strain the components. Adjust the belt tension if necessary.
  9. Reassemble the cassette deck: Carefully put the outer cover back onto the cassette deck and secure it in place using the screws you removed earlier. Ensure that all the screws are tightened but not overly tightened.
  10. Test the cassette deck: Plug in the cassette deck and power it on. Test its functionality by inserting a cassette and playing it. Pay attention to the tape transport mechanisms to ensure that the new belts are operating correctly.

Why is audio warbled and seems slow?

Belt slippage or excessive friction in drive. Roll up sleeves and check it out.

Stop Paying .. ????

if the take up side gets stuck it could feed excess tape and stop the mechanism. Look to see if both reels are turning when you push play. Remove cassette door for a better view if possible.

Make sure your tapes have NO slack in them. Fast forward and rewind one cassette all the way, then try again looking to see if both sides are turning. If not, you may have a belt that is old, stretched and slipping or it's split apart or just fallen off

Rca vhs camcorder cpr300 won't playback or record

This may be bad belts, and what you should check for is the belts on the side of the tape deck toward the lens and pickup(front), and the drive belt in the middle. All the belts are under the circuit board, so you need to remove that to get at them, and then you can replace them with rubber bands of same or slightly smaller size. Use a screwdriver to help get the old belts off, and put new ones on. (In the tight space)

Then check if the tape deck opens and closes, and see if the tape moves when you hit play/record. If you put in a tape you know has a video written onto it, then put that in, and try to play it. If you get a noisy or staticky picture, then try wiping the video head drum(Big shiny cylinder that spins, with the small slits in the side.) with some alchohol and a glasses cleaning cloth or paper. Also, wipe the audio/control head, the silver box that the tape runs across just before it goes by the black roller. Also, check for gunk or obstructions that have gotten in the mechanism of the tape deck in the back. Make sure the video drum is spinning, and that the tape is pulled out of the cassette by some small rollers and wrapped around the video drum DURING playback/record. I say 'during' because some camcorders will retract the tape back to the cassette for fast forward and fast rewind.

I hope you get your camcorder to work! Thanks! 73

Sincerely, Beauregard42. (<-- My YT channel where I have some tech stuff)

Sony TC-138SD cassette deck starts to play then stops after 3 secs. Same when trying to rewind/fast forward

It sounds like the belt is slipping or broken which monitors the speed of the tape movement. When you play or rewind the tape, it thinks the tape has reached the end of play and shuts off. You can try a different tape to make sure the tape does not have too much tension on it. If the second tape has the same result you will need to remove the top cover of the deck to inspect the tape drive mechanism. Make sure the belts and pulleys are clean and replace any belts which have glazing or cracks. If the belt is broken you will need to replace it with a compatible belt of the same length and width.
