The Labtech series of Audio Visual trainers for DVD is based upon the popular brand units, which incorporate the latest industry design features.  These trainers are specifically created to teach operation, theory, repair and servicing.  Special attention is given to fault diagnosis so as to facilitate the teaching of troubleshooting techniques.  These trainers are ideal for use as stand alone units or can be combined with our TV trainers to make a complete Audio Visual training system. The DVD Trainer  covers technology on CD, VCD and DVD systems.  

The each unit is mounted on an attractive chassis, which allows the main printed circuit board to be exposed for ease of work.  The circuit board features a plexiglass cover, which has openings for access to all test points so as to allow insertion of probes while protecting the student and the circuit board.  The trainers allow access to all the factory recommended key points for the taking of measurements, analysis and adjustments.   

The teaching program is designed to follow the service procedures as recommended by the manufacturer and uses the factory service manual in conjunction with student job sheets along with a text on factory servicing and theory.  Each trainer comes with complete courseware as follows:  

a)  factory service manual with detailed circuit board schematic diagram.

b)  student job sheets with fault guide and wiring diagram.

c)  general book on servicing and theory.  

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.  Fault 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.
