This is common to almost all flat panel power supplies. There
are 4 electrolytic capacitors (same physical size) on the
switching PS. There are 2) 1000uF X 10V and 2) 470uF X 15V that
usually bulge and/or fail. You shouldn't pay more than .25to
.50c for each. (I used higher voltage on the replacements of
1000x15 and 470x25) Symptoms of failure a slow power-up or
totally dead.


Look for highest ripple current rating. Nichicon HZ, HN, Panasonic

Correct. Â*'Bob Villa' apparently wants repeat business as his high
ESR caps will fail quickly. Â*Note, 'Bob', good quality low ESR caps
aren't real expensive - you just aren't going to buy them at Radio
Shack or Caps R Us.

Got them from Newark (Illinois Cap. and Rubycon)


Â* Â*Which series? Â*The brand tells you nothing about their
specifications.

You can't fix stupid. You can't even put a Band-Aid on it, because it's
Teflon coated.


I'll let you know when they fail...dip-****! (Original crap lasted 5
yrs)


FAIL. You're out of your element here. Go back and troll alt.home.repair.
Your bull**** might be better told there where you don't have real repair
techs who did/do this kind of stuff for a living.
