In a small-screen portable (as well as a larger) TV, I have found leaking Nippon Chemi-Con SM Series units 
.
The small portable had significantly lower than normal supply rails from the flyback transformer (also causing a picture fault because of a faulty CRT bias filter capacitor
); they were restored by replacing the electrolytic capacitors connected to the rectifiers which were connected to the flyback.
Onto the larger TV, which had two leaking electrolytic capacitors for the CRT bias supply from a rectifier connected to the flyback. This time, an easy fix.
This raises questions about Nippon Chemi-Con SM (not SME or SMH or SMM or SMQ) Series electrolytic capacitors, especially if used in high frequency (i.e. switching) power supplies, and possibly others not designed for this application as well.
Have you seen Chemi-Con SM (not SME or SMH or SMM or SMQ) failures? If so, describe the device which uses them (and if you can, what supply rail the failed units were on).
