LG L1715S TFT power issue

\015 Hi,I have an LG 1715S, just out of warranty. Suddenly a few days ago the screen went blank, and now if I turn it on and off again the picture flashes up for less than a second, then goes again. I've noticed that the screen is in fact still on, just very very dark.I've opened it up and checked the power board for leaky/bulging caps and broken solder but can't find anything obvious. What I did see is a kind of light sooty deposit on the casing behind the power board. It's kind of under a big square black and yellow component (don't know what it is!).Any ideas?Thanks,James\015
