Hi everyone. I purchased a 27" Sony TV and can't seem to get a sharp
picture. Someone told me all Sony TVs are slightly grainy. What?!
So what's all the fuss about Sony then, and why am I paying a premium
for that!?
 
Well !! Take the set back then and get something different.

Is it grainy on RF signals, or watching something through an AV input?

Out of the box, TV's are set hyper-bright, maximum contrast, maximum
'sharpness', and Velocity Scan Modulation on HIGH. All make things look
horrible.

If you have a DVD player, get something like Avia and run through the
video settings. It's amazing how good even a cheap TV can look after even
basic adjustments.

If it's only a problem on RF signals, it's probably a poor tuner.
Unfortunately, with cable so common these days, tuners are getting less
and less sensitive. You might want to try an RF amp to see if it helps.

If it's only on tuner-reception, check for the coaxial-cable, you need a
good coaxial-cable, with good shielding and plugs. If signal can come into
your coaxiale line, you can get the same problem, for all if cable uses the
same or nearly the same frequency as receiving thru the air.

The problem is not that you can't get a "sharp" picture if you are seeing
grain. Grain is noise in the source and is not typically generated by
televisions. The fact that you can see the grain indicates that the set is
too sharp for the signal that you are viewing and you need to turn down the
sharpness. You could get a Panasonic which is much softer looking and will
not show the grain as much, but when you have a clean source it will never
be as sharp. You could also not pay the "premium" for a better set and get
something that doesn't even focus well and not see the grain.

Admittedly, sony sets often have a "bump" in the video response that makes
them more likely to show grain in a noisy signal. This can be easily
mitigated by adjusting the sharpness appropriately.

The problem is likely that the set is sharp enough that you're able to see
flaws in the signal source, it should look great when using Svideo or
component from a DVD player though. Also a new TV will be in need of a full
calibration since they always set them incredibly bright from the factory. I
recommend getting a test DVD like Avia or Home Theater Essentials, they've
not expensive, and they'll step you through setting up your whole system.
When properly adjusted your TV will look great and last much longer too.
 
When out of the box, many of these sets have everything up at max.

Go to the user menu, and make sure that the sharpness is set to 1/2,
and set the contrast to no more than about 2/3 up. Set the brightness,
hue, and color to 50% to start with.

A set with a very sharp beam focus, and very good high voltage
regulation will be able to reproduce flaws or imperfections in the
program material much more easily than a set that is not so sharp.

Use a good DVD player, or a high quality satellite feed as the source
when evaluating your set.

Thanks everyone for your comments. That's great. Maybe grainy isn't
the right word. More like I'm looking through a new pair of glasses,
and they're not quite the right prescription. Even that states it too
strongly.

It may be settings. I'll search out the products mentioned on this
thread to tune it. Thanks for your advice.

Cheers, Jim
 
Jim / glad heart:
You might try backing off on the "sharpness" and the "picture" settings a
little.
A good analogy would be like listening to a scratchy record, poorly recorded
cassette tape or a weak AM station with the treble control turned to max.
One reason the old AM Automobile radios sounded so good on AM is because of
the mellow frequency response of the amplifier circuitry and speaker.......
modern automobile sound systems sound like crap on AM because the extended
frequency response lets us hear everything.
As others have correctly suggested....... test your new television with a
very clean signal source such as a high quality recent DVD.

That really sounds like what you get when velocity modulation is
turned on-especially when watching not so perfect signals from an
antenna, etc.. Unfortunately VM is difficult to turn off and
impossible on some of the standard settings. Some of the Sony's
have a "picture mode" with settings like "standard", "vivid",
"Sports", "game", and "movie". Usually the velocity modulation is
disabled on the "game" and "movie" modes. If you have such a
selection, try the movie or game mode.

I have a Sony 36XBR250 and the only way to turn the VM off is
either by using the Movie mode, labeling and auxilliary input as
"Game" (bizarre, I know...), or turning the sharpness all the way
down to the bottom on the other modes. In the non-movie modes, if
you turn the sharpness up only ONE notch from the bottom, VM is
turned back on (which is a nuisance because the best sharpness
settings on those other modes would not be right at the bottom
but some ingenious engineer decided to lock the two together).

If I understand correctly, some Sony's can turn the VM off from
their service menu. I cannot from mine.
