Question with power for pioneer avic f700bt

When you say loses all power do you mean it shuts down after booting up?
Sounds like it gets to a certain point and tries to load a driver and can't find the hardware to initialize it, it doesn't get an Ack, then it shuts down 'cause the firmware isn't written to deal with a failure like that.
I would try removing all devices and removing all power and hard resetting it.
Pioneer tech support would probably tell you take it to service center or if it's out of warranty, buy another!

Could try flashing the firmware again. But if it's not booting it might scramble the bootloader for the OS.

As always, I have to ask, what's the last thing you did to it before this started?
