We began our takeoff roll and found it strange that our exit light placards and signs never came on or illuminated for our takeoff. Once airborne at cruise the cabin lost all electrical power and went to black. Our phones were inoperative; (Flight Attendant Panels) FAPs were inoperative and forward as well as aft galleys were making audible clicking and chirping noises. Aircraft temperature was impossible to control; many hot and cold spots and intermittent electrical smells. There was no contact from the cockpit whatsoever during the event and communication was completely unavailable. I had a new lead flight attendant so I ran to the front to assist. I began to write a note to slide under the cockpit door; preparing to bang on door or even use emergency cockpit access procedures. Yet; just as we were beginning to initiate this; the lights came on all to full bright locked and phones still down and FAP began resetting. We finally made contact with flight deck and flight continued on with no further incident.
As they began the takeoff roll the flight attendants aboard an A319 began to notice numerous electrical lighting and galley power anomalies that went unattended by the cockpit crew. As quickly as the events started they ended and reset before the cockpit could be alerted.
