Ugly green glow CRT TV

Oct 24, 2006 11 Replies

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???

Move the stuff around and away from your set and watch what happens. Nobody is going to be able to tell you for certain what distances you need between your devices that produce magnetic fields and your set.

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.
