C952 22uf 50v nichicon

That would be my first candidate - but it gets benefit of doubt, being a Nichicon

Do you have something with which to test it ? - like an ESR meter

Does it even get power? Fuse OK? Do you get voltage on the big input cap when you plug it in? Be EXTREMELY carefull not to short anything and electrocute yourself.

Regret I do not have a ESR meter but might be able to borrow one.

Yes there is about 125 volts on the big cap.

Sorry - that voltage is down to earth.

There is 325 V DC across the cap itself.

Yes that would be about OK. So the problem is in the stand-by circuit alone.
