power lights but laser fails to do anything else

ive already resent another ticket ro creality but in the meantime my 40w pro laser will power but fails to show any other lights fan spins but wont fire and no codes they replace my adapter card and cable i still get the same results i doubt its the laser module cause my 1.6w doesnt work either and it doesnt appear to have amy bent pins i even tried disengaging the fire alarms anyone else have an ideas?
