    I get more and more annoyed over the color-balance on my LC37GA4. At a certain level of luminance (near full light) it gets at tiny bit pink (too much red).

    Eg a lamp against a wall gets a pink cirle around it, white T-shirts are suddenly pink, at least parts, in a certain light. And bright faces and even parts of the sky or clouds in the middle of the day get pinkish.

    No help in turning the color-temperature up towards blue since it affects the whole light-scale. DVI seems OK, only TV and analog inputs seems affected.

    I guess/hope this can be fixed via the service menu? Or via newer firmware?

    I would give Sharp a call and demand a fix for this. I'm sure it'll easily be correctable in the service menu.

    If they don't help you, lurk around at www.avsforum.com - I recall there's some service mode info there.

    Does anyone know how to enter the service menu on Sharp LC37ga4? Or most important; is it possible to correct the problem from here? I guess one needs a color-temperature meter to fine-tune this accurately anyhow.

    The pink tint is barely visible. It shows also when I turn the colors off (B&W). It affects a certain point/area in the grayscale, near full luminance/white, and shifts from one grayscale-bar to the next when I turn the contrast or brightness up or down.

    It seems DVI is also affected, so it's a "global" issue after all. Maybe I am to picky, neither my wife ar anybody else has noticed (but I haven't mentioned it either). I see it all the time, though, in bright scenes. Things that ought to be white/light grey are a tiny bit pinkish. Irritating. Anybody; Service menu please! Or is this (im)possible to correct at all?

    I think in a sharp you can correct this from the user menu. I don't have the manual handy anymore (as in the end I bought the Philips 9986) but I remember that there were r/g/b level settings somewhere.

    So you should be, these screens are still very expensive.
