WOW That was crazy, somehow I got into Edit mode on your post!!!

Well the power supply you have has another fuse it is a thermal fuse.
On the cover label of the power it states "Warning do not open electrical shock may occur"

In the photo it is parallel the fuse labeled RT1
This is a thermal fuse that will blow if when hot this will blow before the fuse.

Measure the resistance across this if bad replace, however I found that after replacing other parts could be bad.
Ended up Replacing Power Supply for less that the cost of repairing.
