I've been looking thru my Digikey catalog, and got stopped
by my ignorance about capacitors. The leaky ones are all
the same: aluminum (?) cans with a sky-blue shrink-covering,
stamped with: "10v" "220 [symbol for micro-farad]" and
"sxj". On the next line: "03(3)" and "M(85[degree
symbol]C)".
Hmm the Nichicons are rated -55-105ºC. Did Digikey have any Nichicons?
There are many other silver-colored cans on the various
boards in this unit that are surface-mounted, and if they
are capacitors as well, they'd really have to leak a lot
before I'd be able to see the ooze coming out from under
them.
Well to test them in place you'd need a ESR meter like he

and that's a kit. I once did some testing with a homemade one but now
have Dick's and I'll never go back.
Even tho I have serious doubts about ever get this thing
back to snuff again, I'd sure be willing to spend a few
bucks for capacitors, if I just knew which to get, if only
to rise to the challenge.
Well given what you've already found there's probably a lot more that
aren't leaking or not so much that it's easily noticed. Then there's
the problem of desoldering them from the board and resoldering the new
ones.
It will be a challenge.
