Yep, twice. One a laptop and t'other desktop. But they were CCFL so perhaps not a refutation of your premise  ^-^

And was it just to swap a CCFL power supply or were the tubes themselves damaged?
I know how they degrade over a long time, but they should last almost forever.
I'm just curious.

PlainName:
Tubes themselves. One involved separating all the layers of the screen, and it was never the same afterwards (although it worked it had obviously been worked on). T'other was just a slide-in job one the old one was slid out. Worked great afterwards, so much so that I wouldn't be able to identify which one it was now.

Interesting, do you have any closer information on the age and hours they were lit?

PlainName:
It was a long time ago, so no. At the time the tubes were reasonably easily available, which suggests repairs weren't uncommon.
