There was a time frame where capacitors tended to be less good then before and after...
But not only the factor quality is important.... Was it used a lot? Did the system run them hot? ...
All this together formed a time period where caps tended to explode a lot... Especially in hot systems you use every day.... like PCs, Monitors, Test Equipment and TVs.I have at least 10 Mainboards in my repair pile with exploded/leaked/shorted capacitors.... and not enough time 😁
If all else fails, and the board looks dead, do you think it'll be worth one shot just to replace the caps and see if that's been the problem? On cursory visual inspection they *look* okay to my eye so far. If the board is most likely toast, I suppose at the very least it would be a helpful project to get my soldering skills back up to a better standard, and rather practice on a dead board than a known good one.
Main worry with this board now seems to be that it's southbridge and therefore nothing I can really do about it
