Hi James,
I have exactly the same problem with a tft monitor, and the wrong power supply made it bang with a puff of smoke too.
I am also handy with the soldering iron, so I opened it up to find a capacitor had blown.
I went to maplin and purchased two capacitors, and replaced the blown one.
Sadly the result was that although there was suplly to the monitor, you can hardly see anything on it because it's so dark and dull.
I am researching on this too and believe that the screen itself has blown.
