Do LCD backlights grow dimmer over time?

[fuzzybabybunny]

I just got a second Dell 2001FP to compliment my current 2001FP, and wow, are the brightnesses different!

The new one is noticably brighter and cleaner looking. My old 2001FP is dimmer, and has somewhat of a yellow cast over the pictures. Both monitors have exactly the same color and brightness adjustments, both in-monitor and in-windows.

Yes they do. In fact, their projected lifetime is characterized by how long it takes until they lost half their brightness.

Crud. It looks like I might want to go for a backlight replacement. My warranty is out, and I've been reading online on how to replace the CCFL bulbs. It looks doable enough, but I don't know if I'll be able to get the exact same CCFL bulbs as replacement.

Any idea where I can find these specs for a Dell 2001FP?

How old is it? Prolly have to resort to at least partial dissassembly to be sure of getting the part numbers. Getting them from the manufacturer (Lite-On, BenQ or whomever) may be possible given the serial number but they may not be orientated towards such end-user queries or even particularly willing to help. Even if they will there wouldn't be any assurance of accuracy as there could have been multiple suppliers however I suppose the main fing is that you can get equivalent parts so any supplier and part number should allow that. Just don't count on ending up with the exact characteristics as the new one. Perhaps the manufacturer(s) of each can supply respective part numbers and then you would know if the old could be specifically matched to the new (if supposed-ly equivalent but diff'rent). If the manufacturer info ain't shown check Dell documentation or tcodevelopment.
