If you include circuit diagram of some of this TV or at least explain the working principal then your numerous videos will start making much sense. You can start with power smps, you can explain the rectification section, then to high frequency pwm oscillation {Main winding, axicillary winding and several secondary windings} to the secondary rectification and so on. Next you can focus on LED driver circuits and so much more.

Because this board included the power supply. Some of the tvs has a power supply board, a main board, a T-CON board etc. This one has a combined board, called hybrid board.

Thanks Mr Tevs. Maybe a stupid question, but why do you think the fuse blew? Did the burned capacitor create a short to ground? I thought those blue capacitors were supposed to always blow open circuit. Hope my question makes sense. Take care my friend.
@tevzTVTevatronics
@tevzTVTevatronics Жыл бұрын
Yes, it is partially short to the ground, that's why it's burnt. Sometimes the fuse doesn't blow up because the capacitor first blows open. It makes sense. Take care too my friend.

After repairing the board instead of the fuse, you connected a resistor to the fuse to test the short circuit and connected the board to the electricity, how will you know if there is a short circuit

@@protection4541 If there is a short circuit. I detected it at an earlier time. If the PWM is defective, it will cause the MOSFET to get short during the testing time, and it will cause the fuse to get blown or explode to other components. I am not detecting the short circuit by the resistor, it is for safety. if there is a short. there will be no 12-volt output, and I stop from fluging it.
