Whole inverter measures 675 ohms

[kbs1]

What is shorted? It keeps blowing 3.15A 175V inverter fuse. I have already replaced the original inverter on the board (samsung monitor T220 - 22 inch) with this exact china one a year and a half ago: http://www.ebay.com/itm/281363783165

I desoldered all of the original inverter parts, drilled the board and then soldered +, ground, on/off and dim signals to feed this new inverter. Then attached the new inverted onto the board and fit snugly in metal casing of the monitor.

Worked flawlessly but now it just keeps blowing the fuse. New one is on the way but since it takes 1 month to deliver from china, I hoped I could fix this one in the meantime. This is my main monitor, now running on 17" backup one. All readings on photos. Any clues what might be shorted?

The order of my test leads is important (diodes). Negative DMM test lead is black on pictures, positive is red. - maybe the invertor checks out ok, but the why does it blow the fuse?

Thanks!

Re: Whole inverter measures 675 ohms

Woohoo, it works!! ) It was not an inverter problem after all, just the OLD iverter in some way shorted 1,5 years later ;-) I just cut the trace that still went AFTER the fuse to the old iverter section and its parts (bottom side of the board / upper side was desoldered to make room for new inverter). Now the fuse goes directly to the chinese inverter only, old inverter remains are now completely cut off (that's the ones that blew the fuse). Works like a charm!
