What other tests would you suggest? I do have a capacitance meter to check
values. I would have desolder them of course. Would you test just the
electrolytics or all of them? I don't have an insulation tester though. Any
other tests?

I have checked the ESR on all the electrolytics, they
are all fine.
Prior to all this I had replaced C439 with a higher voltage rated
component, as recommended here: https://trmm.net/VT100. I used a 100uF
part, rated at 100V. I had also replaced C437 as that had a high ESR
prior to seeing this problem.
Is there anything else I should check?
ESR alone is not enough to validate
capacitors.
