P1000-1BD help

[Grave41]

I have read an earlier post stating q1001, 1003, and 1004 are likely HUF75344g's. I want to make sure before I replace them, also, is it common to replace other parts when those three fry? If anybody has a schematic of the board, I would appreciate it if you could send me a copy.
board # 1325-55802-01

Thanks
