Unfortunately I don't know the make and model of the device, the customer took it to the technician to check if it had burnt components. One of the components had exploded, it is the input varistor in addition to two fuses one of 5A and another of 1A.
I will attach photos of the board in question,
The first thing I changed was the blue varistor on the side of two jumpers. Then I put the fuse F1 and fuse F2. When measuring the resistance between points A and B in the electrolytic capacitor 6800uF / 16v I obtained a resistance 0 ohms the same thing about capacitor C32 in points C and D on the side of the integrated U11. Some component is shorted, it can be some integrated or some capacitor. The question is how to know what component it is. This plate is double-sided .
