I have the Central Machinery 1 H Mini that came with the laser. It is a little over three years old. Worked great yesterday. Doesn't work at all today. Checked breaker, switched outlets, check connections of power cord to switch - still won't work. It does nothing when I flip the switch. Any other suggestions, or is it time for it to move on to that great junkyard in the sky (the one where it only has to exhaust fresh, sweet smelling air and not burnt acrylic fumes)?
