Description

COLOUR TV TRAINER Black and White TV Trainer is an ideal training equipment to teach the operation of colour TV receivers. The complete circuit of colour TV Receiver is printed on single PCB. Sectionwise coloured printing on PCB helps in easy understanding of function of different blocks. More than 50 test points allow the analysis and monitoring of the signals in different sections. It safe to operate because all the test points are protected against accidental shortcircuits. By using the fault simulation method, it is possible to introduce the most common breakdown and their rectification. Technical manual includes circuit diagram with component list of each section. Test point details with typical voltages and wave forms are provided in the manul. The Trainer has been specially designed with Sliding Main Board with locking facility. The detachable CRT Unit is another feature. It can also be used as a normal desktop Black and White TV Receiver.

  1. TV Receiver in open form with all components & controls placed on single PCB
  2. Each circuit block shown in different colour for easy identification
  3. Solder less fault creation &Rectification
  4. Legend printing on PCB
  5. More than 20 test points
  6. Compact Design-Sliding Main board with locking facility
  7. Fully documented Operating Manual with glossary of terms
  8. Manual and remote control operation
  9. Detachable CRT Unit.
