I have a problem with a lightbulb energy saving that flashs still turned off.
Could be an electrical problem?

I mean the lightbulb flashs even is turned off and the problem is in all the house.

Howdy micros12-ga,

Are these "energy savings" light bulbs (they sometimes look like a tube
in a spiral design) or standard light bulbs?  Thanks!

Looking Forward, denco-ga - Google Answers Researcher

Yes, they're a spiral design light bulb but the problem occurs also in
other "energy savings" models

Peter Parry posted this in news:uk.d-i-y on 17/7/2001:

It's caused either by leakage across the switch or, 
more usually, simply induction from adjacent current carrying cables. 
The new CFL lamps a use high frequency switched mode power supply in 
the base and the induced voltage is enough to charge the capacitor 
until it has enough voltage to start the invertor.  The invertor runs 
for a fraction of a second which is enough to cause the tube (which 
in this mode has no filament heaters) to discharge momentarily.  It 
takes a period of time to allow the charge to build up for the cycle 
to repeat.

... If you undo the lamp holder and temporarily connect a normal 
filament light bulb across the holder for the fluorescent the 
filament bulb will act as a drain and the flashing should stop.

I would add: Some low energy lamps have an internal drain resistor to
stop this phenomenon. It is also possible to fit a drain restistor
externally but I'm not a qualified electrical engineer so won't make
possibly irresponsible suggestions.
