2200uf 10v cap replace with 6.3v?

Yeah if it's too tall it would still be good for testing. If it works, great, you know what the problem was.

Then you should order some decent capacitors for a full recap anyway, especially if the rest are the same brand as the visibly failed one.

if i have the choice, should i care about other factors besides the uf and voltage?

there are no other 2200uf caps in the psu. others in it are 16 and 50v.
why would it be a bad idea to extend the legs on the cap and place it elsewhere?

You could use a 16v one, higher voltage rating than the original is OK, just not lower.

Extending the leads is a bad idea as it introduces additional resistance which defeats the purpose of a Low ESR capacitor to begin with. Also may increase lead inductance which adds its own problems.

it is a bad idea,
you could use it with the case open to see if it fixes the problem though.

what other caps are in the psu - 10v or 16v type?

i found a single 2200uf 16v SXE brand with
(M)105c | 7(7) | 8I
on the side, would this be a good replacement?

although, i just checked. i might not be able to get the case back together if i do use that one, its too tall. by about a quarter inch
But! if i can run small wires and hot glue it in place elsewhere on the board... - is this a bad idea?

if the voltage is even close to 6.3v the sanyo will explode - literally.
i wouldnt chance it.

if you have a broken computer, see what's in the psu - that's gotta have 10v and 16v rated caps in it.

i have a westinghouse monitor 19" that had been taking 5-15 minutes to come on, so i decided i'd open it up and check for bad caps. well, i found 1 bulging.

the bad cap is 2200uf 10v capXon p723. radioshack never carries anything and i dont want to wait 3 weeks to get caps over the internet. i happen to have a broken computer with a few 2200uf 6.3v sanyo n.e.91 caps. would one of those work fine? or would it just go bad right away since the slightly lower voltage rating?

and should i replace more than just the bulging cap?
