NOT TO BUY OR OWN , CCFL SCREENS
HISTORY and specific HP only models of PC that love to fail for bad LCD CCFL tubes:
Most of these PCs died 5 years ago from these short lived, CCLF back lamp tubes.
THEN CAME WHAT? "LED back lamps came later"
The bright white LED was introduced in September 2003 by Cree, but it took many years for PC makers to latch on too this device. (slow my guess, is was due to LED costs in 2003 ,or near)$2 a pop is super expensive.
CCFL's ended about 2010 in Displays.(LED takeover) Just as CRTs died down fast, and for sure helped with the push over.
These tube lamps can fail dead, or go dim or go yellow or flicker or the inverter power supply for it is bad. (some PCs have many tubes and only some die making a huge BLACK BAR)
Do not forget that many old CCFL laptops you can buy a LED conversion upgrade for many, as seen in ebay...(For HP621 / G60 / DV6 / CQ60, and more )
This HP only , table is not complete: (one trick is to pretend to buy a CCFL for you screen, if can't? then it has none.) Trick 2 is to read the service manual, see words toxic for Hg Mercury , bingo CCLF.

The old monitors (etc) don't tell you its CCFL or LED, as LED not invented yet, (bright white LEDs for display) so the never even say CCFL.
The newer books for newer displays, with LED ,flat out say in the spec. it is LED backlighted.
