4 Time Blink Error

[Akifay]

I have Z5 Compact E5803. When i try to power on red notification blinks 4 times. Does anyone knows this error code?

I find my own answer. Thanks to Sony's ignorant online support employees (!). My phone wants to say something to me and every one says "send your device to nearest service center".  i just want to know 4 leds meaning ! 

Finaly i went to service and they said youre out of warranty beacuse of realy little crack on my phones frame.(shame)

Today i came home and disassembled device's LCD flex cable.

4 LED BLINKS WANT TO SAY; YOUR LCD OR BACKLIGHT HAS BROKEN !!!

 that is prenventing your phone to boot up. If you disassemble that flex phone boots up.

Change your LCD !

this size of crack enough to void your warranty. (i said "phone doesnt boot up" to service.)
