2 Seconds to Black (Power LED Still Lit)

[GY-Repairs]

Hi All
Such a shame that my first post to the forums is a plea for help. However, I have been hovering recently and you all seem to offer comprehensive and helpful advice. Here's hoping that this is going to be a permanent stay

I have here an LG Flatron WS1934S-BN TFT monitor with a "2 Seconds to Black" error, I have been concentrating on PC and Laptop repairs of late and if a monitor had blown we chose to just replace it. However, with the current economic climate looking so grim I was hoping to move into the component repair side of things.

This particular monitor fades to black after 2 seconds however, the blue power LED remains on. Other monitors that I have seen with this problem seem to turn themselves off. Am I looking at a specific error here?

I have stripped the unit down and removed the power board (images can be found at http://www.mediafire.com/?h3cmdzq7yovfij5) I cannot see anything out of the ordinary but would prefer the experts to take a quick look if they dont mind to confirm for me

Many thanks in advance
Derry O'Neill

1) 2 seconds to black is documented in posts #19, 20, and 21. Post 21 and my sig file will tell you how we want pictures and where. Follow the instructions EXACTLY.

We prefer pictures hosted here for many reasons including avoiding malware, ads, popups, etc at offsite hosting.

2) The most likely candidates are

a) bad ccfls
b) bad ccfl wiring (especially the return wire at the top of the lcd)
c) bad caps
d) bad secondary inverter transformer windings
