Your laser power supply might have gone bad. Disconnect power wire to laser and replace fuses again. Now power it on again and see if the fuses blow again. If they blow again with the laser tube disconnected then the supply is shorted. If the fuses do not blow then the laser tube is shorted and needs to be replaced
