I don't think it's possible to start the power on the phone without the on/off button. I recommend that you contact a service location or your local Sony Xperia support (http://www.sonymobile.com/global-en/support/contact-us/) for assistance with repairs.

Purple led means that the phone is connected in fastboot mode. This mode is activated if you hold vol+ when you connect it to your computer.

How about starting the phone in Fastboot mode (Volume-UP when USB is plugged in) with Flashtool running.

Then you have the "Reboot into Android" option available.
