yan na po ang pictures ng board sir natad123.. ano po kaya ang dahilan nito kung balik pumuputok ang fuse nito? saan kaya ang short nito?

cold check d667,b647,a1941,2n5401,2n5551.. may sira sa mga transistor na yan.. usually yung a1941 or d667.. wag mo isaksak until di mo nakikita yung sira para walang madamay na iba..
