For the most part i'm happy with the picture the set gives, but i've noticed that whenever there are white credits over a black screen, the edges to the letters are very slightly diffused, not crisp.
-however-
in that split second as they fade out, they become substantially sharper.
i can't replicate it by adjusting the user settings anymore. they're all pretty close to the initial adjustments i made with VE. brightness and contrast settings are already as close as possible to baseline.
would this be a gamma problem?
is this what they call blooming?
like i said, for the most part the picture is decent, but if i could tweak this aspect, i'm sure i'd notice a bit more snap in the picture as a whole.

What set is this?

Did the settings in VE that adjust blooming look ok? Have you tried turning the contrast down?

Assuming you have a RPTV it sounds like a convergence problem to me. I had a similar problem with my set. The white text had a slightly blurry blue edge to them. It was fixed by going into the service menu and adjusting the convergence grid.

sorry 'bout that. Its a sony 53HS10...a notoriously soft set in general, i realize.
but this has me stumped because, the text can look very, very crisp, but its just in that milisecond as its fading out. this makes me think, oh yeah it must just be a brightness setting, but i don't think so, because both my brightness & contrast settings aren't much above 30%, if that ( they might even be more around 20%).
i've adjusted the convergence (with the remote) but haven't physically opened this up ( and don't think i want to) to mechanically focus.
having played around w/ photoshop, i have an inkling of gamma, and know there are settings in the service menu to adjust this, so that was one guess.
i should say, that as it is now, the picture doesn't really bother me... the diffusion isn't anything close to being severe, its just that i get that little milisecond peek of what could be and it scratching my head wondering what i can do to keep it always like that.

Are you watching during the day or night? Is your viewing environment dark?

generally pitch black. its in a basement.
now, with the convergence, if this WAS off a bit, wouldn't i get one of the colors as the diffused area...the (minor) diffusion is as white as the text.

Try reducing your contrast and sharpness -- if that helps, your set is blooming.

I would get either the Avia or Video Essentials dvd to set the television properly.

Also realize that the protective screen that is over the actual display's screen will cause this from the reflection of the bright whites shining off the inside of the protective screen back onto the display screen. Try removing the protective screen and see if it goes away. Some people remove the protective screens for this very reason but others like myself are fearful of damage to the display screen by leaving it exposed!
