I have alpine that has no signs of life at all. The power supply is a bit different than I am used to. I believe these small silver components to be transistors but unsure. I removed the shorted components still nothing not even a short curcuit?

Yes. Those are the PS FETs. The attached photo shows the bottom of the FET. It's on the face of a TO-220 transistor for scale. If you don't find any shorted, don't do anything to them. They can be difficult to replace.
This supply is a full bridge design, not a standard push-pull design.

I know that one of the output driver ic is blown and four fets are shorted, I also removed a diode it was shorted,none of them are reading shorted perry. Typo error. They all show fine, so I need to figure out why I have no power at all. The no power at all issue.
