A1200 busted. Power not OK

U49 is a surface mount transistor. The D3 A1 code on it might be able to help us track a replacement. Many times a normal size transistor can be substituded for the repair if you can find the specs for the old one and get the legs soldered in correctly. It's probably an NPN high frequency transistor if I had to guess at it, but it could just as easily be a PNP. What make you think that it bad?. You didn't give much detail. Does "Broken" really mean cracked, busted, snapped off the mother board some how? I'll do a bit of searching and see if I can come up with the specs and a replacement number. (If some one doesn't beat me to it). If you have any other old pc boards lying around, you might look to see if they have the same transistor you can pull and use. But doing surface mount can be tricky.

BTW, taking a closer look at the pins on that, it might even be a voltage regulator..... now scanning more docs....

@acill

That was one possibility, but check the datasheet. The pins don't match. It has the layout of a voltage regulator. BUT it's always hard to tell with some of these smt's.

Ok, here's the likely suspect...2n2222a Transistor in a SOT-89 case. And here's a possible replacment if you solder in the correct pins to matching points on the mother board....Radio Shack 2n2222 transistor in a TO-92 case. And here's a nice page with SMD info and soldering technics... SMD Help. Just ask if you need more.
