Left shift of picture with NTSC DVDs?

Hi All,

I have finally managed to get a TV that I am pretty happy with (Sony
KD32DX150 - Ł300 over my original budget, but it doesn't make that
dreadful 15.6 kHz whining noise...)

I have one outstanding problem with this set. I am using it with a
Pioneer DV-656A DVD player, and the picture is pretty much perfectly
aligned for PAL discs. However, with NTSC discs, the picture is
shifted about 1.5cm to the left - obvious with both NTSC THX Optimode
test patterns, and the setup menus on the DVD player.

If the DVD player is set to output NTSC, the shift is more pronounced
with RGB than with composite; if the DVD player is set to output
pseudo-PAL, the shift is the same with RGB and with composite.

Note : this is not the RGB shift that some people complain of - the
RGB and composite signals are pretty much perfectly aligned with PAL -
and in the case of sending pseudo-PAL, they are both perfectly aligned
1.5 cm away from where they should be!

Is this
a) an inherent issue with NTSC display on PAL sets?
b) something for which there exists a service menu tweak on the TV?
c) a fault with this particular TV, for which I should request an
exchange?

I should also point out that the same shift happens with PAL vs NTSC
DVDs in my PS2, so it is definitely the TV at fault.

Many thanks for any advice,

Simon

I have the same problem with a Sony 32FQ80. Also playing MK:DD
on Gamecube at 60Hz produces the same result, whereas 50Hz it
is OK.

It does seem though that what is lost on the left side of the picture is
gained on the right.

This sounds like RGB shift.

The line timing for PAL and NTSC are a few uSec (micro-seconds) different.
The field rate is also different, thus causing the field rate to have some
errors as well. This is why you have the shift.

I can suggest something to do in the service set-up, but your set will not
be standard for your broadcast system. When converting from one standard to
the other using home equipment, there are compromises. In the broadcasting,
and professional TV production facilities, they spend a lot of money on
equipment that can compensate for these errors.

I've noticed it with Sony, Panasonic and a friend's Philips TV, and
had always simply assumed that it was something that happens when you
watch NTSC stuff on a TV that's optimised for PAL.

But on my present Sony, it seems a bit less pronounced when using the
S-video input, so I now use that. (I've been told off by eagle-eyed
people for doing this, but I really can't see a difference in picture
quality between RGB and S-video on my latset set - call me cloth-eyed
if you like...)

I've had 2 Philips widescreen sets TV sets (different models) and have now a
Metz Artos TV (all RGB SCART, all PAL/NTSC sets). I've had them all
connected to a variety of DVD players (Pioneer, Harman Kardon, Toshiba) and
none of them exhibited this RGB shift when playing back NTSC disks through
the RGB connection.

In other words it is not 'normal and within spec'. Try the DVD player at a
mates place and if it doesn't have a problem get the TV fixed and/or
exchanged.
