1. Maintenance information
Here is the circuit block diagram of the super chip TDA9370, as shown in Figure 2. In the figure, the function code of each pin and the direction of signal output/person flow (indicated by arrows) are marked, and the function, voltage and resistance test data of each pin are further explained in the form of a table, and the transistor model, application parameters and Replacement model. This is very helpful for overhauling TDA9370 super chip color TV.
