I've seen this happen twice with a bad ground power unit feeding less than 395hZ. Start the APU, pull the GPU and the lights go back to normal.

I always wonder what these eratic power supplies may do to all those little, very expensive black boxes, whether it is from the old unstable, outdated GPU or from an onboard power supply.

According to my cabin crew yesterday, the evacuation horn is apparently very quiet in the cabin, about the level of an electronic game or mobile phone. (In fact, one voiced her concern that she might not hear it at all in flight 
She was new........)

Well, when MH started operating B777 to ARN, which has a strict no-APU policy, we asked for two ground power units. Then we found out that there were two FEP cables on the stand. What we didn't know was they were both connected to the same 90kva power supply, which is a bit marginal for a B777. One day the FEP started fluctuating and then failed. After this event it took us about 3 hrs to clear all the faults on the aircraft, and the crew ran out of hours and we nightstopped. A very expensive failure. Since then we use one of the FEP outlets , and a GPU and have had very few problems.
