    • Remove the two 15.7mm screws on the top of the device first, and then the two 26.5mm screws on the bottom (they are in the smaller holes and larger holes respectively) using a Phillips #1 screwdriver.

    • You need a spudger to orient the bottom screws so that they can be removed.

My 450 turbo will not turn on. Power light does not light. Power supply lamp is lite and plug provides 24V DC power measure by volt ohm meter. Is this fixable? Do you think the motherboard went bad?

Only print about 100 labels per year and have had the unit for 5+ years.

I’ve had the same issue - very little use from new, it just stopped working , now when plugged in there’s no blue light, just a repetitive sound but nothing else happens - could a faulty motherboard cause this?

In our unit the step-down converter, make the incoming 24 Volt to 5 Volt, are in malfunction an kill other components.

On the mainboard, the Q3 has make a shorting on the incoming 24 V powerline. Not shure if the PWM Controller is still OK (IC with 8 pin’s).

The reason for the malfunction is the possible of a shorted capacitor.. Bad circuit for the power!
