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!
Chad.

What environment were they operated in?
Cigarette smoke/nicotine?

In some cases, I think that it's just inherent in LCD technology. I am
currently watching this on an HP 19" widescreen monitor which is perhaps 3
months old. Not a cheap or poor quality 'no name' unit. I am using Outlook
Express with a full white background. To the average eye, it looks very
good, and I'm pretty sure that most people would struggle to find anything
wrong with the picture, but if you really want to get pedantic about it, the
far left and right sides of the screen are definitely not as white as the
centre - unless you move your head right in front of those areas, at which
time, they become brilliant white, whilst the opposite side, which you are
now looking at from an even more oblique angle, becomes a little worse. Even
though these days, LCD viewing angles are quoted at 160 deg or better, I
find that the *optimum display quality* viewing angle, is rather less than
that, for just the sort of reasons you are describing. Do your yellow
patches vary with viewing angle ? That might perhaps give a bit of a clue as
to whether it is a genuine problem, or just 'the way it is'.
