My PS died it has tamper proof screw heads. Is there a know part that fails inside or should I pitch it.

The fuse inside usually blows. You can get the proper screwdriver, but the best advice is to step up to a bigger transformer. You can never have too much power.

I thought most transformers had an auto reset. Hence the flashing green light when it shorts.

You can get security screw bits at Harbor Freight. If it’s the newer triangle screwheads, there’s a 3pc screw driver set on amazon.

Sorry, I was thinking of the CW-80 which looks identical. That power supply has a fuse.
If the CW-40 Powermax does not work, just replace it with a bigger transformer like the CW-80, or a non-electronic postwar transformer.

There may be a fuse in the transformer windings. FWIW, I've replaced some of the fuses in various transformers and power bricks (Legacy #990), with a PTC. Solves the problem of ever having to open it again, and also provides circuit protection.
