I'm not too familar with this model, but to give you some pointers, you will find when you have this problem the fuse will go straight away as there will be some of the semi-conductors short circuited. Check your bridge rectifier diodes & also the chopper transistor in the power supply. As a general check, test most of the diodes & power transistors & replace any that read short circuit on your meter. Hope this may help you as a guide line.
