I don't have the Schematic but did you replace the fuse once? You may need a Slow Blow Fuse. They are marked and just look different
A
slow blow fuse is different from a fast acting
fuse in its capability to withstand transient pulse currents, i.e., it can withstand the surge current upon power-on/off, thus ensuring the equipment works normally. Therefore,
slow blow fuses are often called time-delay
fuses.
Hope I helped If I did please "Like"
