Hi,
I just bought a Samsung dlp tv (HL-P4674W).
When I view something in 4:3 the left and right black vertical lines are not
straight.
The have a small curve. I was wondering if anyone knows if this is normal.
Thanks

Require loosening of the actual screen assembly mounts to allow the screen
to flatten out and get rid of the viewed (pincushion) distortion. In these
specific devices the only thing that would typically cause the symptom is
the physical curve and stress on the screens. Seen this on many Samsung and
a few other DLP sets. There are no pincushion correction adjustments in
these sets. Be advised, this is normally not a DYI procedure, requiring
disassembly of the set.

That seems to be common in the wide screen models most noticeable when
viewing 4:3 material. The term is convergence and can be adjusted, usually
in the service menu.

J.C. may I professionally ask how to converge an DLP SET??

I have only heard the term convergence used to describe aligning the 3
colors in a CRT based set. Are you sure that is the correct term?

Thanks!

I don't think there's any way to adjust this with DLP. If this were a
CRT-based TV you could adjust it electronically; if it were a LCD-based
projector it would probably be the fault of the lens and therefore
incurable... a DLP projector just shouldn't have such a problem! If it
does, I sure don't know a cure.

That is specifically why I posted my initial reply, actual case symptoms and
rectification per the help of the manufacturers respective service technical
lines. I have done quite a few DLP and LCD Rear Projection Monitors devices
in this manner and in almost every case resolved the symptom to the
sastification of the consumer.

Sorry, should have said Screen Geometry. Adjusted in the service menu. Not
recommended for novices, but there is a lot of info in various HDTV forums
like http://www.avsforum.com/

a technician came today. he put a signal generator in one of the tv's inputs
and after he looked at the curves for a minute he said that this is
acceptable on a dlp TV and can not be adjusted.
I am kind disappointed that this is expected on a $3.500 TV
