When you checked fuses(F5 or F6, I can't remember), did you pull them from the holder or check them still in the holder? If in the holder, you can sometimes get false "good" reading on those.

If the fuse is good, then I would move on to checking the driver transistors. Q44 & Q5 are associated with the Auto Launch, and Q42 & Q3 with the VUK.

Before getting into testing the transistors, did you check the fuses on both boards- PPB and the Power Supply board?

Check fuses 5 & 6 on the Power Supply board.
