Do not remove the power input assembly if all you need to do is replace fuses.
Figure 1 - Fuse Holder
1. With your finger nail or a screwdriver, pry the fuse holder out of the power input switch as shown in Figure 1 above.
2. Either replace both fuses, or use an ohmmeter and verify the continuity on both, replacing the one with little or no continuity. Replace fuses with Time Lag Ceramic Body Cartridge fuses, Rated T5A, 250V (Melco PN: 010162-05). Fuses of equivalent size, capacity and quality can be used.
3. Reinstall the fuse holder in the power input switch assembly by pushing it in until the face of the fuse holder is flush to the face of the switch.
