Colour TV Trainer For Electrical Lab Training

Colour 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. section wise 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 short circuits. 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 Colour TV receiver. TV Receiver in open form with all components&controls placed on single PCB Each circuit block shown in different colour for easy identification Solderless fault creation&Rectification Legend printing on PCB More than 50 test points Compact Design-Sliding Main board with locking facility Can be used as Desktop Colour TV Fully documented Operating Manual with glossary of terms Manual and remote control operation Detachable CRT Unit. Experiments that can be performed Study of RF-Section through test points, fault simulation&rectification Study of VIF- section through test point, fault simulation&rectification Study of Video/Chroma section through test points, fault simulation&rectification Study of System Control Section through test points, faults simulation&rectification Study circuit of Horizontal&Vertical Oscillator&Output sections Study oc circuit of Horizontal&Vertical output sections through test points fault simulation&rectification Study of R-GBvideo output Section  study of Audio Sound section and many more.
