My monitor stopped working. Simple solution, replace capacitor. Done it many times to other monitors. This time however when I went to test it, like a stupid dumbsh!t, I had left a screw out and the back of the power board and it shorted out to the back of the lcd and made sparks and now there is nothing. The monitor is just DEAD. It was was working after I changed the capacitor but then the circuit board sagged down and shorted out when I moved it from my work table over to the computer.

-The part that shorted out is circled in red
-The piece it is attached to on the other side is in green
-And I am assuming the blown part is in blue??

No other parts seem to look fried or anything. I'm not looking for a pinpointed cause as that would be impossible online but what I am asking if the MOST LIKE PROBABILITY for what shorted out is the piece in blue.

The part number on that transistor is 2761L and the Monitor is a Samsung SyncMaster 920WM. I would go and buy another monitor but of course its New Years and everything is closed.

This happened WAY too early in the morning. So anyways, I just spotted the white T2A 250V fuse by the green wire (F801). Didn't remove it but put continuity leads across it and the meter made no sound. Fuse is blown to start off with. Hoping thats all it is but of course I don't have that value fuse on hand and all the stores are closed so I can't get a replacement today. There is another fuse beside the green circle (F802) and that one DOES have continuity.

My solution was to go to Goodwill (on New Years day) and buy another monitor for $8.

They actually had a Samsung Synchmaster there (no idea which model). I got a different one, the Samsung was bigish and cost too much ($14.95). I did not want a big monitor. I needed a small one to use as a second screen.

Nothing like that open where I am on New Years Day. But I managed to get my hands on replacement fuses today and when I soldered one in it fired up and gave me the digital/analog flash the said to check the input cable. Put ALL screws in this time before moving it over to test and luckily it works again and was only the fuse.
