Symptoms and Repair Tips

Symptoms: half load arm
1.) eats tape.
2.) tape loads incorrectly.
3.) cassette ejects with a loop of tape caught in VCR.
Check half load arm to see if it pivots freely. The half load arm keeps tape in contact with the ACE head, which feeds information to the reel time counter. The half load arm on this VCR sticks. The cause is dry oil.
The Cure - clean and re-oil the pivot point for the half load arm. Make a sketch for the spring to reassemble it correctly. To get the height right, mark the nut and count the turns. Difficulty rating 2 - easy.

Basic VCR Notes

This VCR uses an idler with a single gear for all transport modes. It has seperate motors for cassette loading and the Moving Mechanism. The moving mechanism motor is underneath the deck and the cassette load motor is on the right end of the carriage. A front loading type cassette carriage is used. The mode switch is a circular type and is located on the bottom side of the deck.

Tape End Sensers - no special precautions necessary with top cover off. Keep direct sunlight off VCR and don't use extremely bright light over bench to avoid false trips of tape end sensors.

Removing Cassettes That Won't Eject

Removing the cassette can be easily accomplished by a procedure called Hand Cycling. If there is tape outside the cassette, we need to put it back inside. Locate the Moving Mechanism Motor below the deck. Rotate the motor shaft while watching the roller guides. The roller guides may not start moving right away but as long as the master cam gear is rotating you will eventually get there. Keep turning the shaft until the guides are fully retracted.

Now we can reel in the tape. Locate the reel drive pulley underneath the deck. With your finger, rotate it counterclockwise (as you look at it from the bottom) until all the tape is back inside the cassette. This works most of the time.

Finally, you can eject the cassette by hand cycling the motor shaft on the right end of the carriage. Keep turning until the cassette is completely out.
