Colour TV Trainer
COLOUR TV TRAINER
This trainer has been designed with a view to provide theoretical and practical knowledge of a general REMOTE COLOUR T.V. on SINGLE P.C.B. of size 19"x15” with FAULT CREATING FACILITIES to create more than 75 faults.
The complete circuit of Remote Colour T.V is printed on single PCB.
1. All parts are soldered on single pin tag for easy replacement and fault creation.
2. Fault creation facilities are provided by removing jumpers, by rotating presets, by tuning coils, by adjusting trimmers and by changing parts
3. About more than 75 faults can be demonstrated on this trainer.
4. Section wise different coloured screen printed circuit on the PCB for easy understanding of functions of different sections.
5. Typical ICs are provided on sockets to provide facility to check similar other ICs and also to create The faults by inserting faulty ICs in the sockets.
6. Explanation, Observation, Alignment and adjustment of internal and External controls is possible at a glance due to single PCB.
7. Easy identification of different parts of Remote COLOUR T.V at a glance.
8. Easy measurement of Voltages and observation of waveforms at any point. Also typical voltages and waveforms are provided.
9. A manual having 30 practical’s is provided with this trainer.
10. The whole circuit of Remote Colour TV is explained section wise in detail in the manual.
