It looks like it's just an unpopulated foot print.

Blown Up is absolutely correct.  This is the same as my 54710, I just had it open. The missing chips are for the four channel models.
These machines used different motherboards and different power supplies also. Makes working on it harder....

The author tells you that Timebase ASIC is missing. And this is a big problem. This is a custom HP chip.

The topic starter, you need:
Time Base ASIC 1SE6-0056 = 54810-89002 REV A = 54520/40 = 54810 /20 = 54835/45
