I recently got a Packard Bell CGA monitor from 1988 that let out the magic smoke and I want it to work again. Parts of the pictured board smell of bad electronics but I could not find anything burned. I originally thought it was the Samwha CE-W 220uf 250V 85C input cap, so I replaced it with a Panasonic equivalent (an EE series General Purpose 105C cap). The monitor let out more smoke (there would be no video at any time the monitor was on and it would smoke after about 10 seconds). So I decided to look at all the capacitors in the monitor. Other than one cap near the HOT section (circled in the attached picture) that I can't identify without very awkward removal, I was able to identify three different series of caps:
Samwha GA (all 160V)
Samwha SA (most of the large ones)
Chemi-Con SM (most of the smaller ones)
Quick searching wasn't coming up with much on the Samwhas, but the Chemi-Cons seems to be general purpose. I wouldn't think there would be any low-ESR caps in such an old monitor. So my plan is to recap the board full of Panasonic EE series caps (or equivalent).
Before I pull the trigger on buying the caps to fix the monitor, I would like a little input on if those caps are a good option or if something would be better. No matter what I will get 105C temperature-rated ones so that it will be reliable for many more years.
