Oh, nobody would be repairing flat screen monitors (though I replaced CRTs while I was in), but get into radars and fire control systems and servos and such and those definitely get repaired onboard. When the choice is replace a 50 cent resistor or send the module off and wait six months for a spare that costs the ship half a million bucks, you better believe people get the job done. I owned the 2M shop on a CVN for a while. We repaired millions of dollars worth of equipment.
