what do you mean for 'working', them still had power boards swapped?
A monitor can't contaminate anything, it's a stupid thought..
maybe your monitors are produced same day as them has been bopught same day
and caps are equal and fails near same month or week.

Before and after I had swapped the power boards, only one of the two
monitors worked--and it contained the same power board each time.

Yes, both monitors were bought at the same time, and used roughly
equally. But one monitor started failing over 18 months ago, while
the other just started this month.
