Hi!

My new Samsung SlimFit 29" TV is doing some strange things like
vertical green glow. It is in the middle of screen appox. 10 cm wide
and appears only when TV screen is black (nightscenes, pause between
ads). When TV is turned off green line is still there for 1 or 2
seconds.

I did degauss but it didn't help. Actually everything was OK for about
30 min. Then I turned TV off. Next time green vertical line was back
again.

Should I bring TV to sevice repair???

Look for magnets in the area, such as surround sound speakers, etc.

Would you be so kind and tell me how far must speaker stay not to
trouble TV? In my case it is 50 cm

And there is smth else: under TV is DVD player and AV receiver. Both
are in metal bodies so there must be no magnetic field. BUT there is
also AC convertor 220V to 110V and that is not metal finish. Plastic
only. It is approx. 70 cm under TV. May be this is guilty one???

Most likley. The best thing to do would be to unplug everything except the
TV and see what you get.

If it is not working then to repair???

I have heard that magnetic field makes irregular fields on crt screen.
In my case there is one 10 cm wide line from top to bottom. Regular.

Is there a magnetic field around AC converter if it is turned off or
unplugged???

Oh God I hate when things like this goes wrong. In my country there are
damn slow repair services ( OK. I'm going to the war!!!

Transformers can be magnetised when off, so unplugging that wont do.
However I dont see how a magnetic field could give you a green vertical
line on screen. Admittedly I've little idea of what could.

I rather doubt it's a magnetic field problem. A distinct sharp edged
artifact like a vertical line is normally associated with an electronic
problem, possibly a bad cap. Or, possibly something simpler like a black
level adjustment. You may be seeing the sync signal feeding through to
the video somehow.

If it were a vertical band at one edge I'd nod to that, but in the
middle? I'm just plain puzzled on that one.

The horizontal sync pulse is more or less in the middle of retrace.
