This is almost always caused by shorted output transistors. To eliminate other possible problems do the following.
Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down (goes into protection), the amp likely has blown output transistors.
Generally, an amp with blown output transistors can be repaired.
