I moved house and carefully moved my k40 but now it won’t work
What could be wrong with it
Check all connections - especially the power cord as some were not soldered - only twisted together.
Did you unplug it from the old house and plug it in new house? 
If you scan the pics in the forum you will see all sorts of ‘inventive’ ways to connect wires the manufacturer used - the only thing missing was bubble gum (possibly)
Yeah im getting power to the unit just the lazer is not working im thinking its the power unit
Ok. power into the power cord
What then - does it reach the power in terminals on the power supply unit?
If so then do the PSU outputs have any life. If the power actually reaches the PSU and you get nothing out - it is the PSU - Light Objects sells replacement units.
@greg_greene could you send me the link please
