I've been poking around in the AD3000ip to check out the layout of the LNB switching supply, as I have in the past had failures of a couple transistors due to silly shorts brought on by failure to make sure the cabling from LNB to f- plug is sound (I'm always swopping and re-terminating connections).
Q904 and Q909 are in my opinion the most likely suspects to be damaged if a short in the cable occurs for any length of time.
Here's my effort at drawing the schematic. I haven't provided values for the semis, just swop like for like or use any medium power rated transistors.
