VP6's Blowing thier caps, noooooooo
VP6's Blowing thier caps, noooooooo
VP6 Boards are dying! Damn caps!!!! But we have 2 different VP6's here, one with the detachable "Greenie" chipset heatsink and ones with the black epoxied heatsinks. The ones with the black epoxied ones are blowing all thier caps (Maybe because they are 2+ years old and never turn off.) But why would this one kick the bucket before the ones with the greenie? They were all bought the same time long ago. Doh @ Abit
ok...
the direct signs of a failing capacitor
1: a loud pop and a god-awful smell of burnt electolyte (you will know when one pops)
2: a bulging capacitor, mainly the top will buldge out, look at a new capacitor and notice how it's very flat at the top, then look for some that aren't flat...
those are the 2 most assuredly ways i know of by just looking at a cap to see if it's bad

Big electrolytics dying smell disturbingly like babies nappies/diapers!
On the top of the capacitors you will see some stamped in marking in a Y shape or similar, these are engineered to rupture before dangerous pressure build up takes place. I have been hit by the flying can of a suddenly failed electrolytic in the past and it stings!
As described above if the tops of the capacitors are not flat the chances are that they are on the way to failure, on my VP if you look at all of the capacitors some are noticeably flatter than others, on the BP some are decidely pointy and they are beginning to rupture....
In my case I am going to replace them with larger value capacitors with especially low esr rating and high ripple current rating, I have found some capacitors stocked by Maplin in the UK and intend to replace the larger value capacitors with 4700uF 10v capacitors. I am not short of clearance in either of these computers so can stand slightly taller than standard capacitors. I am sticking with 10mm diameter capacitors so they will fit ok in the places where they stand in line.... I will post an update when I have done one, Xmas was expensive so roll on pay day!

I will try to take some pics of the duff capacitors, looking again I see two of them in the BP6 associated with the front CPU are actually growing white fur on top. Since I am off work today while my car is being serviced I am sorely tempted to fix it with whatever capcitors I can find around the house.
I was really asking about the appearance of the caps before they go bad, to see if there is any sort of pattern emerging as to which motherboards are likely to fail. For example, my BP6 which has no sign of failing, has dark green caps with gold markings.
Do you mean the caps had turned black, or they had black packaging to start with?gabumon wrote:did notice buldging caps, were black ones,

grsshppr_km: Xcellent information! Especially, this link in the article:
http://home.att.net/~garyheadlee/services.htm
Sent an email to find if he still repairs BP6's. His page says all capacitors over 1000uF will be replaced. $55 for a BP6. Very interesting.
Thanx...

The caps were black to begin with, seems the newer replaced ones are green, we havent had any problems with the green ones (even older ones that have not been fixed) I got my vp6 board in the mail 2 days ago, and im glad to say its once again working 100%InactiveX wrote:I was really asking about the appearance of the caps before they go bad, to see if there is any sort of pattern emerging as to which motherboards are likely to fail.
