When you power a phone on, it performs a Self test on various parts (signals between chips, software checks etc).
If any of these tests fail you will get the "Phone Startup Failed" error you see.
You really need to take the phone to a service center so they can see what has caused the failure and repair it.
At best it will require a software reflash, otherwise it will be a hardware fault
