I forgotten how many psu's in various items of equipment I've seen overheat, usually due to poor ventilation, causing scorch marks on the pcb and slowly 'cook' its electrolytics as a result, hence the recommendation to replace if they in anyway look 'tired'. |
Absolutely, yes - there's no doubt that electrolytics in hot places are more likely to fail. But in this case, given the original poster's apparent level of experience, I felt it useful to point out that the scorch marks can't have come from the capacitors.
I confess I'm from the 'if it ain't broke, don't fix it' school...and finding out what's really 'broke' is most of the fun for me!
