Xperia SP cannot turn on, LED functioned but not the screen (please read my problem description)

yesterday I finished changed rom to cyanogenmod 10 from http://forum.xda-developers.com/show....php?t=2677173

I'm using CM-10 smoothly, then I update to cm11 because there are system updates, I update through custom recovery mode, CWM. Then I rebooted the phone, after rebooting the phone, my xperia sp cannot turn on again, but the led lights still flashing when charged, sometimes green, sometimes red. if it is not to be charged only the green light every few minutes.

when I connect to flashtool, writing "device connected in flash mode"

bootloader locked position.

I've tried

power + volume down (green light blink once)

power + volume up (blue light blink once)

press the off button on the back

connect to a PC while pressing the volume down.

using pc companion, but the pc companion cannot recognize my xperia sp.

flashing using stock rom, after finished flashing, I still cannot turn on my SP.

overcharging it for about 12 hours

the screen is still black

I connected to a PC while pressing the volume up = LED turns blue and then a few moments later became green again

I hold the power button, just blinking lights.

the screen does not light up at all

if I charge it, the LED lights in red and green sometimes.

I will appreciate your help. and if my question does not fit the rules, please tell me, I will immediately delete it later and ask to another forum.

Thank you :')

You might have to stop by your local Xperia care to get it checked

that will be the last thing I'm gonna do, but is there another way to fix this?

@rosinante

I think that's the only thing left to try.
