      the fuse never blows without a reason.unless there was a power surge and the movs of the power supply protected the psu and burnt only the fuse but this is rare.in any case replace the fuse with the same rating otherwise you may damage further the device if there is a short somewhere.

Upon desoldering the encoder, one of the pads (bottom right) for the push function fell off with the solder so the encoder itself was fine but due to getting pushed a lot and strong, the pad on PCB just had teared off.
