Notification led blinks 4 (four) times?

I was have problem with my lcd: there was picture but no backlight.

Then;

1-Pulled off battery

2 -Cleaned flex cables with alcohol.

3-Putted everyhing back.

4-Putted battery back.

5-Tryed to power on.

Now:

When i try to power on vibrates 1 time as normal and 5-6 seconds later red led blinks 4 (not three) times. No thing happens. If i try to shut down by sim slot button its acts normaly and vibrates 3 time.

Anyone knows what is the meaning of 4 time led blink.

Sony Online Support emloyees made me crazy. I find my own answer. When lcd or backlight is broken or cant work properly device prevents boot up. 4 time blinks wants to say that! Thanks for Sony's ignorant employees.

I replaced the LCD screen and back camera. Now it won't boot up. There is no response at all from any of the reset option. The 120 second reset. The power+volume up, power+volume down. Nothing. When I connect to charger and hold down the power button, the red LED comes on for a second, then turns off, the phone vibrates 3 times followed by the red LED turning on again for a second and then turning off. Then the process repeats. Holding down the power or the 120 second restart button while plugged in yields the same results. I tried repair using pc companion, doesn't work.
