After just under a year's use of this board, I found a bad cap on it during a visual check; I 'd just read (not for the first time) about these and since I had a few rare occurences in the days before ...
I found one bad Cap among the lot (so far); on my board I found a MIX of cap makers - SANYO (good) and GSC (bad).
About 'GSC' I 've read a lot of bad things on another forum / many owners reporting bad caps from this maker !!!
I 'm looking for GOOD replacement caps to do the replacement myself:
GOOD are Sanyo, Panasonic, Rubycon, Chemi-con, EPCOS (Siemens before).
Sanyo you need to look for EXR Hybrid series
Rubycon you need MCZ (or MBZ) series
EPCOS you need B41859 or B41886 series
Chemi-con you need KZE, KZG, KZH series
Panasonic you need FM or FC series (EEU-FM = 105°C /7000h)

I've been working on a 1984 Sanyo 27" color TV which had a smattering of bad caps in the video switching circuit. I found this oddball little 1uF 25V cap which looks to me like an early polymer, but I can't find concrete info proving it. I know Sanyo was a big player in early polymer cap development and this is the time period where they were just getting on the market, so I'm wondering if anyone has crusty old datasheets that could help identify it and determine if my suspicions are right? It has the same epoxy end seal and font/formatting as some old stock Os-Cons I've got laying...
