Seems likely. Can you rig a little current to flow through a resistance to be mild like
20 milliamps total, then do you have a 6 or 7 digit voltmeter? Probing will show dropping volts along power
rails until you get next to the offending tantalum cap, then not change much if probing farther along than that...
