Question about ViewSonic VX900 19" LCD Monitor
I use 2.5A PICO fuse, but before wasting new fuse due to short circuits you should solder in a 1/2w MOX resistor in place of the fuse and measure the voltage drop across the resistor so you can calculate the current draw by the circuits, if the resistor burns up right away, then you have shorted out output transistors in the transformer driving section. Also check the two large electrolytic caps also, if they are bad, it will cause the fuse to blow also due to high frequency oscillation.
