The Labtech  VCR Trainers  has been specifically designed for the teaching of service technicians in the operation, repair, servicing and troubleshooting of video cassette recorders.  The trainers are based upon VHS video cassette recorders/players from world famous manufacturers such as National/Panasonic, Sharp, JVC, Hitachi, Sony, etc.  The teaching program is designed to follow the service procedure as recommended by the manufacturer and uses the factory service manual in conjunction with student job sheets, along with a text on VCR theory and operation.  The program covers both the electronic and the electro-mechanical aspects of VCR servicing. 

The VCR is mounted on an attractive chassis and is modified to allow all parts to be visible for examination and servicing.  The circuit boards features a plexiglas cover so as to protect the circuit board from dust and damage.  All controls built-into the circuit board are functional as well as the remote control.  Test points have been brought out to a special PCB which groups all test points together and clearly labels them to aid in the diagnostic and testing process.  This feature also reduces the risk of accidental damage to the VCR main circuit board by locating the test points off the main board. 

The VCR trainer may be used in conjunction with the Labtech TV trainers so the student can view the video output.  A unique fault insertion system is built into the trainer for student instruction purposes.  The system features a Schematic Block Diagram silk-screened onto an integral fault board that utilizes LEDs to indicate the nature and location of the fault.  The fault is activated by touching an electronic switch with a special teaching probe.  Single or multiple faults may be introduced at any time.  Faults may be visualized by use of the LED lights or the LEDs may be switched off, thereby not allowing the student to know where the fault is.  This feature is ideal for testing purposes.
