I have two fluorescent tubes in the kitchen. Having been buzzing, flickering and turning themselves off for a while I replaced both the tubes and the respective starters, assuming this would eliminate all variables.
However, now when the lights are on they turn off when flicking light switches in nearby rooms.
Also, the kitchen lightswitch itself gets a bit warm when the lights have been on a few hours.
This never happened before. How can I identify the cause?
