Doesn't seem to me it could be the transformer/controller as it either puts out voltage and current or it doesn't. I can't think of any way it would selectively operate certain bulbs. You said wiring is fine, but you should check voltage at the end of the line to ensure it's getting close to 12 volts all the way down the wiring.
