Here's my take. Those IKEA cable lights have two conductors (the two cables) that run at 12AC. The lamps get current by being wired between them. Twelve volts AC is supplied by a transformer that has a 230v primary winding, and one or two secondary windings that each supply 12v AC. They don't use rectification or smoothing capacitors to supply DC. If the transformer has two secondary windings, the two secondary windings are wired in parallel so that the current capacity at 12v AC is doubled.
If one of the secondary windings in the transformer goes open circuit, the transformer can't supply the current to light up the standard population of bulbs. It will only supply 50% of the usual current and some of the lamps won't work properly.
This could, of course, be utter bollocks.
