Have Samsung S27D850T monitor that doesn't turn on when cold. This might not be the forum, but people here know this stuff.
I replaced small small caps, then I saw this:

Then figured it's worth a shot to replace: N-Chanel 600V 12A KF12N60.
Got 3-pin ones (couldn't find 2-pin), now I really don't know what to do 😕
Here's the parts I have :

This is a MOSFET and the middle pin is connected to the tab. So if the tab is connected, you don't need to connect the middle pin.

That's kind of what I was hoping for, but the tab has heat sink compound on it, I don't know if it conducts electricity or if the middle tab is not needed at all.
I was just looking at a random TV board and I noticed some MOSFET's have 3-pins and some have 2-pins, but all are connected to heat sinks.
I replaced the MOSFET and monitor blew up 
The 2-pin was a N1106.
I did not change that one, well I soldered it back in, since I had no replacement.
The 3-pin seemed to be correct.
Only difference I saw in the 3-pin I replaced, is that the original had a plastic coated tab and the one I put in was bare metal.
I saw sparks and then smoke, then no worky 😀
The 2-pin was a N1106.

The plastic tab isolates it from the grounded metal of the heatsink....
Are you sure the two pin thing is a MOSFET, and not a diode which would have two pins.

N1106 was two pin, I told it off and then soldered it back on.
Then the other "thing" was 3-pin ; I replaced that one with this:

It had the same specs I think, but the ON SEMI I got was bare metal.
I saw sparks, heard noise and then smelled smoke.
That was it for the monitor.
