I've been asked to help fix a 400Hz converter that has been sitting unused for a couple years. Upon inspection I found several burnt resistors and damage to connected components. I'm looking for troubleshooting advice to find the cause and prevent burning up any new parts.
Other than the 6 burnt resistors I've found 2 shorted snubber capacitors. The large blue capacitors aren't giving any capacitance reading so I guess I'll need to replace them as well.
