Identifying the surface mounted parts on the main circuit board can be tricky if one does not have a reference book.
As the parts are arranged in two sets of three and usually only one set of parts, in each of the two sets, blows up a good solution is to use a scrap board for parts.
However, the small parts are all obtainable from Farnell for example.
Typically:
U10 is a J312 opto coupler; Farnell part 1085048
D17 = BYG22D; Farnell part 1021749
D32 = "YW" or MMSZ5V1; Farnell part 1431291
D23 = "V3V" or MMSZ7V5;Farnell part 1431295 but no longer stocked
D26 = D23
D328 = BUHC312 = SMBJ18A an 18V TVS diode; Farnell part 9843990
R64 12 ohm

The coding of the parts may vary slightly depending on the particular maker.

Sometimes one or more of the 220 ohm resistors on the back of the board fails and, as a matter of course, change the 47uF caps associated with a blown up set of diodes, although these could be OK.
I have an idea that many faults originate at the three relays, for example if a pair of contacts welds together.
Remove the plastic lid from the IGBT module and you can see what has happened.
