ive got a LG 47" LCD TV 47LF66 which works perfectly for 2mins then the screen breaks up into vertical lines and goes blank except for a few pixels, also ive noticed the remote works when the screen is fine, when it starts to break up the remote doesnt respond, first thought it was the tcon but changed it and no difference. had a look at the powerboard and found a blown cap (25 680uf) so i replaced it and just to be on the safe side changed all the surrounding caps but still no difference, can anyone help please
