Small electrolytic capacitors under the overhang of the heat siinks. Most of what you are probably used to looking for are capacitors in the 1000 to 3300 uf range. The ones I've had causing problems similar to yours will be 100uf @ 35v. These will be much smaller in physical size, but still the same type as the other ones you've seen.Thanks for the insight guys.
But now I am (more) confused about what a cap under a heat sink looks like.
The removing it without taking the heat sink off part is bewildering me.
Make sense now?
