Yes you are right. Swap the lamp unless you have a ccfl tester.

I recently had a problem with a dell 15" monitor blinking on and off.
I first removed the 4 ccfls, plugged each one into my old IBM Thinkpad T23 laptop inverter and they all powered up.

However, they were all very black at the ends of the ccfl and also one of the ccfls was not very bright at one end.

Because the above tester and my laptops inverter has no feedback circuit is it not likely that a failing ccfl would appear to be okay via this method but when plugged back into the dell monitor utilizing a feedback circuit the ccfls may then cause the blinking.

In other words, the only real way I believe to check whether ccfls are causing a monitor fault is to swap them for new ones.

Please correct me if I'm wrong.
