Our kitchen has three under-the-cabinet flourescent lights. Suddenly two out of the three tubes won't come on.
The one nearest the switch still comes on, but not the next two.
It's not the tubes, because I tested all three in the one that works, and they all come on.
Sometime ago I noticed a very slight, intermittent popping noise -- almost like a water-drip -- in the area of the second on the line.
I notice that when I take the tubes out of the non-functioning holders, the ends of the tubes are quite warm.
I've tested all circuit-breakers.
Any guidance appreciated.
