How do you unlock mini head cleaner tape

SOURCE: Panasonic AG-DV2000 Mini DV loading problem

the "dv sensor"is actually a mechanical lever built into the cassette housing that moves the reel tables to match the reel spacing on mini or full-size DV tapes. check to see if this assembly is free to move. if it binds up, the reel tables may not move as far as they need to, and can cause problems similar to the one you're seeing. to inspect the mechanism, you need to remove the cassette housing. if you don't have a service manual, get a tech to help -- it's a delicate procedure for the inexperienced.

Dear FixYa customer,

There can be several reasons for the tape spitting back out including, a defective tape, foreign object/lablel in the cassette compartment, unit in timer recording with tab knocked out on tape and then actual mechanical and electrical faults.

I will concentrate on the mechanical and electrical faults here, since you can verify the others.

Electrical, would include the Power supply, and Micro processor circuits.
A weakened power supply due to deterioration of the filter components will kick the tape out if the power supply voltage drops below a certain value. The filter components deteriorate with age and heat, and then put out less voltage.

There are critical timing circuits, and sensors that control the mechanism positioning and send signals to the Micro processor. The tape in sensor, mode switch, and LED are common faults here.

Mechanical faults include the Cassette Loading Assembly, Capstan, and Drum motor. A fault in the casseette housing assembly that won't allow it to load 100%, a Drum or Capstan motor that is sluggish or frozen will send a signal to he CPU to kick the tape back out.


The Power Supply is a common failure.
An experienced technician can verify the power supply voltages and replace the filter components for approximately $25.00 plus labor.

Thank you for using FixYa
