Hi, i'm trying to fix an AC control board that is no longer produced by Mitsubishi
I have already bought and substituted broken components (a resistance, a capacitor, a transistor and a diode). When i try to connect the board again it instantly blows the 250V 1A fuse. I don't know if there is something short-circuited or maybe i missed something with transistor (it's not the same as the previous cause it's not longer in production, it was an 2SC4960 now is a KSC5027OTU ) because the new transistor has an Ic of 3A while the previous has an Ic of 1A as i see from the datasheet. Or maybe the problem is now in the transformer but i cannot find the model. I'll link some photos of the circuit section
Thanks for help
