Went to visit my mother yesterday and noticed the picture on her old curved screen avant has developed a flicker/wobble which looks a bit like a picture from a vcr with the tracking out. It seems to happen after the television has been on for a couple of hours and varies in position on the screen. Apart from this the picture is sharp and the colour is superb. I know these sets aren't worth much these days but does anyone have an idea if this is likely to be economically repairable
thanks for any help!
