greenish tinge in dark scenes - lcd rear pro

Archived from groups: alt.tv.tech.hdtv (More info?)

Hello all,

I'm very much a newbie here - not only to this NG but to HDTV. I recently
purchased a 155 cm (61" ) Samsung LCD Rear Projection TV and am very happy
with it, but have noticed that there is a greenish tinge, particularly in
dark scenes, and particularly in shadows (although not really in shadows
cast by bright sunlight). This tinge is not at all apparent in brighter
scenes. It's noticeable regardless of the input - DVD, satelite, or normal
free-to-air TV (whether HD or SD). All the other colours seem fine - even
the greens are usually okay in brightly lit scenes. It's not unbearable by
any means, but I'm kind of stumped by it. I was wondering if anyone might
have some idea what might be causing this and if (and how) it can be
corrected? I've tried playing with the various colour settings, but with
only marginal success. Could this be just a feature of LCD rear pro?

Many thanks,

Ian (Australia)

It's SP61L2HX

Would that cause these types of symptoms? Ie...greenish tinge in shadows
in dimly lits scenes?

The fix is to

Thanks

Thank you for this. The odd thing, though, is that the blacks are actually
quite black. It's the shadows that are greenish - and usually only shadows
in scenes that are lit by electric light - that is, not shadows that are
cast by the sun. Computer generated images, with computer generated shadows,
are all fine too. It's weird - as if it for some reason gets the colour of
electric light slightly wrong.

So you had an experience with service that was ineffective and unacceptable
and you went back for another set of the same manufacturer from the same
dealer? What will you do if this one has a problem?
