My phone is not showing anything after flashing recovery

Hi guys, i'm in trouble i flashed one recovery s/w on my sony xperia l , now my phone is not showing anything .. No notification lights.. No volume up and down button doing any action.. My phone starts with a vibration - which it used to.... additional info: "my phone has no OS installed, and I flashed "recovery-clockwork-touch-6.0.4.3-quincyatt.img" after this, my phone is not showing anything...previously... TWRP was installed & blisspop OS was running.... but, It was not able to flash cm12.1 or cm12 so I changed recovery software to "recovery-clockwork-touch-6.0.4.3-quincyatt.img" ... now phone itself is not starting...when I press power button it vibrates for some milliseconds.. & it all black nothing happens.. not even "sony logo" displays"

Phone: Sony Xperia L
status before: TWRP recovery was installed and blisspop ROM was installed
status now:
**No OS installed (as I wiped data in order to install CM12.1) and phone is not showing anything not even "sony" logo. **when I press volume up/down button it's not coming to recovery mode or boot loader mode...
**Phone is not recognized by my Computer also
