David,

Thanks for the added detail. Those of us who have only purchased TVs at
decade-plus intervals can only guess at what controls might be available
for tweaking which is why I asked in the first place.

The picture also distorts badly depending on blocks of bright or dark in
the scene. The effect for viewing the cable news channels which favor
such screens is quite disconcerting when several rectangles of
different colors are displayed: vertical lines go all wobbly. That leads
me to think that there are issues that are not simply geometry setup
that make me dislike this set in spite of some cute features (notably
the ability to fine-tune each channel to optimize the picture). Since
Circuit City has a 30-day return policy I'm just going to turn it back
and look more carefully at different brands.

Question: calling on your expertise once again, have you a suggestion
for a smallish color TV (20" or less) with a better picture?

There is not service mode adjustment for tilt correction on that set.
Usually the tv sets/monitors that have tilt correction coil and circuit
include either an adjustment control on the back of the set or in the user
menu. They also usually do not have a pincushion, trapezoid, or other fine
adjustments unless it is a 27" or larger and then not the elcheapo sets.
The service mode on that model includes the mininal h-size, vertical size,
and vertical centering and linearity. There is an H-position for the image
as well.

The 1cm-2cm at the top is within tolerance for that size of set. If the
total shift was 2cm across the top or bottom, it would just be outside of
tolerance for that size.
The 7mm at the bottom is not. The adjustments of that type on a small set
like that are typically done by physically adjusting the yoke position,
which also requires a full purity, convergence, and geometry adjustment. It
is part science and part art to do this as judgements usually need made to
average out the errors that will be there.

If the store will allow, your best bet is to take the tv back and ask them
to open up any new one you will be taking home so you can bring up some
quality images. Hopefully they will have cable you can hook the tv up with,
or borrow a test signal generator (or ask them to put one on it if they have
in house service). This will allow you to check the performance of the set
before you get it home.

It almost sounds like the tv set wound up with a defective yoke to be off
that much. I do not think if the yoke had shifted enough to cause that much
geometry problem that you would not also see a convergence problem or purity
problem in the corners.

David,

Thanks for taking time to write back.

At the top of the screen, a line that is ~1.0 cm from the top edge at
the left side of the screen is ~2 cm from the top edge of the screen
at the right.

Text scrolling by at the bottom of the screen is about 7mm above the
bottom edge at the left and dips below at the right. My kids are grown.
I no longer find a protractor around the house to measure angles. The
effect is pronounced and annoying.

BTW, David, if you re-read my original question, you will see that the
degree of tilt was not so very relevant to my actual, specific question.
I was asking if there is a service mode control, accessible from the
remote, that would permit me to adjust said tilt. I never got a clear
answer from someone who knew one way or the other. Do you know?

Thanks again for all the effort you put forth to help me find the
answer to my question.

Then next time you post for suggestions, post some important relavent

"Somewhat tilted" has a very large interpretation of what that means.

That

is why I tried to give you the information of what is 'normal' and can

be

due to the earth's magnetic field on a 27" size set so you could compare

how

much it was off and how to see if it move into the correct position.
Samsung is well known for very wide variances in tolerance due to the

cheap

design and often uses bonded yokes to the picture tubes making no
adjustment possible.

A 16" is too small to have any kind of tilt correction for the earth's

Who said that the earth's field is doing this? This is more like an
adjustment of trapazoidal distortion on a monitor. I have many and I
have them adjusted quite nicely. The picture on this TV is out of whack.
Tilted so blatantly is just plain bent.



Even if the shop 60 miles away did check the adjustment, which probably

is


within specification, any direction you face the tv set is going to

cause


tilt one way or the other.

Sounds like you're making the assumption that I'm too picky. Thank you
so much for your 'objective' opinion, in spite of having not seen
the picture. I think you're wrong, but you've done me a favor.
You've convinced me that I should just make the trip to
the retail store and trade them since I think most techs probably
have your level of contempt for the customer. I don't need someone
who can't see and doesn't care doing an adjustment that they'll
probably screw up.



Just exactly how much tilt are you seeing? A 27" size tv can have as

much


as 1/2" across the width of the screen in the middle and still be

within

what the earth's magnetic field could be causing.

My 13 year old Sony 27 inch TV has none of that tilt. It's picture is
nicely aligned and has been since it was purchased.



If you face the tv set either directly east or west does the tilt seem

to go


away? If so it is probably adjusted properly.

Nice of you to ask after assuming that I've tried nothing and have
simply been overly critical. No, the tilt is quite obvious regardless
of orientation of the set. The defect is marked and quite annoying:
text running across the bottom of the screen on several channels is
shaved badly at one side. Parallel lines across the top and bottom
are markedly askew. $60 TV's at Walmart perform better. If that's
within specs, the specs are bogus.

Thanks so much for your helpful input.

I have a brand new 16" Samsung TXN1634F color
TV with a somewhat tilted picture. Nearest Samsung
warranty shop is 60 miles away. Is this adjustable
via a service mode? Or is it going to involve going
into the cabinet and mechanically moving the yoke?

Does anyone else have experience with this set? I
could trade it back to the retail store if I drive
a little farther than the service shop.

TIA
Don
