    this is really hard to explain but...
    when im watching region 1 dvd's i get what i thought was magnetic interference from the front speakers on the left and right hand side of the tv image.. im guessing its not that because it only occurs when im watching region 1 movies...

    could anyone help me figure out what esle it could be and a way to get rid of it? im guessing its an ntsc issue.. its just a shame coz lots of my dvd's are r1.........

    thanks

    Hi,

    Possibly magnetic coupling between some component operating at mains frequency (probably a transformer) in the TV and the C.R.T..

    When you watch 50Hz sources, the coupling is unnoticable but 60Hz sources beat with the 50Hz field producing a 'flutter' on the picture. I get the same effect on my Panasonic TX-33A2 on 60Hz sources, caused by the proximity of the audio power transformer to the rear of the C.R.T..

    If this is the case with your set, there is not much you can do about it.

    i had the same problem with my old 4:3 tv
    it looks like two matching semi circle waves of interference on the left and right hand side of the picture (only with region 1 dvds) - it doesnt cover the picture or anything but is like an almost transparent thing over it.. although the picture near the edges where it is happening does seem to be not as good quality....

    does that make any sense?

    im already having to use s-video inputs on this tv coz LG told me the weird black bands i was getting via scart RGB were coz the RGB didnt like the ntsc signal (but its fine thru s-video)....

    the next tv i get, im making sure that its super ntsc compatible!

    He's mixing lies with the truth, as there's no such thing as NTSC when you're talking RGB - just 625/50 or 525/60: HOWEVER, the black bands you're talking about (did they emanate from vivid light sources etc?) are where the tv's moire "doesn't like" 525/60. Apparently, defocussing can help, but I knocked that on the head and just bought a better set.

    the black bands did emante from vivid light sources.. it wasnt a constant thing just occassionaly annoying..... like i said, that was just when using scart RGB - switching to s-video got rid of it completely..

    how does that help the current problem?
    is there a way to fix the current problem or am i stuck with it until i can afford a better set? what should i be looking for in a new set to eliminate the problem?
