Side thought: I had one of those blow up on a BA23 chassis a few months
ago. When I opened the supply it was full of aluminum paper from the
inside of the cap; glad it didn't short out any other components.
Remove and replace.

I do understand that these are common film capacitor types. There is
one more smaller .10ufa RIFA branded capacitor hiding near the center
of the PWB.
A couple reasons I'd like to have a circuit diagram is to know what
the RIFA capacitors purpose are. The other is, a couple of the
electrolytic capacitor are double covered with what appears to be
rubbery heat shrink tubing, therefore I cannot read what their value are.
Cut the heat shrink with an X-acto knife and peel it off. it should
leave the marking of the cap intact. if there are 2 layers, it may be
the inner layer is the original factory marked wrapper for the cap. So,
you might try to not cut through the inner layer. But,, maybe don't be
too worried, as the caps definitely sound bad.
