Actually I repaired one by replacing one cap, sorry don’t have a list.   The bad one was 150uf, 400 volt, 85 degree, but could be others.

Got one I can borrow? ;)

Easier to just "shotgun" 'em. Do you have a list of what it needs? (Or do these units have different power supplies, making a "universal" list impossible, per Murphy?)

I’ve already had to replace aging capacitors on the U4K PSU board.   I would check them with an ESR analyzer.
