The ET-893 is a suitable equipment for the learning of the flat screen television sets operation equipped with TFT-LCD and Plasma technology that allows the student to become familiar with the more advanced technological innovations, as well as Digital Terrestrial Television (DVB-T). The trainer includes a failures generation module.

The ET-893 block diagram shows through an intuitive way the different stages that compounds the flat screen receiver.
