Hi,
I am just getting into LCD repairs and I have a batch of liquidvideos
L17LCD2's .. They all seem to exhibit the same picture quality when it
comes to the whites!.. All display an off white with or yellowish
tint instead of a clean white background. I am unable to adjust it
out in user settings. Before I order new ccfl lamps I want to be sure
if what I'm experiencing is a common symptom of the lamp starting to
go. Want to be certain it's just not inherent to cheap LCD monitors.
Could even the filters be yellowing for some reason perhaps? Thanks
for any insight!

It's the lamps.

But think twice about getting into replacing CCFL's. Often they're
buttoned up under layers of covers, tape, aluminum tape, and glue.
They're about as fragile as a supermodel's marriage and emit a few
milligrams of mercury vapor when you break them. And you will break
them, both old and new, until you get the technique right. It takes
the steady hands and sharp eyes of a surgeon to R & R these and get a
good outcome.



It depends, some are very easy to replace, others are nearly impossible.
Pull the lamps out of one of the monitors you have first to see if it's
something you want to do multiple times. Also at that time you can power it
up and verify that the lamps are in fact off color. It is possible though
unlikely that the plastic light guide or reflector has yellowed from the UV
or heat.
