What are you trying to achieve?
You won't get a schematic of the board, it's HP proprietary, but if we know what you are trying to accomplish, we might be able to help.

We are trying to replace a "3 lead surface mount" on the board. One pin is tied directly to the center pin of the DC input jack. Another pin to ground and the 3rd goes to a fuesable surface mount fuse. The part number on it is 403RJ, but we have not found where to purchase that part from. Thanks for any help you can provide. ![[pc3]](/data/assets/smilies/pc3.gif "[pc3] [pc3]")

The device is a transistor in a SOT-23 package, however the code appears to be a production code rather than a part number. I would say your best bet would be to post over at the tek-tips sister forum that deals with the engineering and hardware side of things, somebody there will quite probably have more experience at that level of repair detail.
We are more the "box builder" and configuration johnnies rather than being "down and dirty" with those solder fumes
Though I have been there in the dim and distant past. ;-) and still do occasionally.

If you had a part number, Digikey and Mouser are two spots I use for components. Since you dont you may be able to find similar on these sites.

nastewart,
Can you provide a wider view shot of that transistor? There may be some indications printed on the board that will help me.
Also, you may de-solder it, and take it to an electronics component shop, and let them match it.
