525 line based NTSC, then the resulting video quality will be modest. With
a HD digital signal the quality is vastly improved. Seems to be a problem
with a lot of the HDTV products currently operating on the existing system.
Possibly tweaking the focus a bit may slightly improve the quality.

have PAL and I think that you can use it with NTSC also. But it does
not seem to matter what video source I use. Satellite decoder (digital)
dvd or a computer. The focus is off so when text i displayed it is hard
to read. I think that the focus have degraded from when I bought it 10
months ago. Since I don't have access to any repair center where I live
I would like to try to fix it myself so if anyone knows how to adjust
the focus I would be grateful. I have tried to buy a service manual but
the company that sells these in Sweden doesn't even bother to answer
the e-mail I sent them. Samsung does not sell them directly here in
sweden so if anyone know where you can order it i'd be grateful to know.

Is it focus, or convergence? If it's convergence, the colors, red,
green, and blue, won't be lined up on top of one another. I think
Mute-1-8-3 will get you into the convergence menu, but I can't
remember the keys involved in the procedure. It isn't a bad procedure
when you know which buttons to use, but it's not easily guessable.

Tom,
I think the problem is focus, because the colors seem to be ok. For
example In the tv menus the red text is ok but is has a ghost image
next to it (same color). I tried your key combination but that did not
seem to bring me into the convergence menu.
Tom MacIntyre
You need to evaluate something white to get a good indication of
convergence, but it does sound like a focus problem, by your
description. I left out one important detail...you start with the set
off, and press Mute-1-8-3-Power. If it's focus anyway, those are
likely adjustment pots on the focus block inside the set.

We did one yesterday...789 RGB select...100+ turns off red, the button
in the same position on the right-hand side of the remote turns off
the blue...s-sel exits, add-erase saves, maybe MTS...Vol+- and Channel
+- move the grid color selected in a LR or up-down direction...you'll
have to experiment. The one I worked on yesterday was different than
the manual, and I had to fish for the proper key selections a bit.
Tom
PS-If you bring the grid up and it looks good, just get out of the
convergence menu...resist the urge to play. There is a hypnotic aspect
to doing convergence...you always want it just a tweak better...:-)

Hi all... just a bit of extra info. I have the Samsung SP434JMF, which is
sold in Australia, and I managed to get hold of the service manual (I have
my ways, and I love the internet!!!), and the
convergance adjustment for my model was [conv] then [mute] then 1 - 8 - 2
The conv button is the "user" convergance button.... I needed to press that
first....
So very similar..... Reading this thread got me going on mine, as I just
got it returned from a repair, and they adjusted the convergance for PAL
(Australian TV) but NOT NTSC, and the majority of my DVD's are NTSC. I was
appaling, the convergance for the NTSC signal was out by 2 centimetres for
red and blue!!! They hadn't even bothered to fix it!
So being an EX electronics tech myself, (i'm into computers now) I threw
myself into it and fixed it myself.....
Imagine the shock the "busy" TV repair place got when I said, dont worry I
had fully adjusted the convergance, there is no need to come back to fix it
yourselves... I told them, and they were suprised, anyway since my TV is now
out of warranty, I think any future problems, and I will be drawing on my
experience as an electronics tech that I was for 7 years (fixed a few tv's
in my time as well....)
cheers....
