My Xperia Pro has been running into some problems with the display as of late. What happens is after a short period of keeping the phone idle, it doesn't wake up. When the power button or the home button is pressed, it just shows a blueish-black screen and the lights between the physical buttons light up. Same thing happens when the keyboard is slid out. The backlight of the keys work but the screen still shows a blueish-black color. After trying again and again, the screen finally works, just to run into the same problem after locking the screen.
I tried changing the ROM and flashing a different kernel to no use. Then I finally flashed a stock Gingerbread firmware. Now the screen doesn't show any blueish-black shade or anything else at all!!!! I have currently just left my phone to charge because I don't want the battery to run out during this crisis. I have also re-booted many, many times by pulling out and re-inserting the battery.
Any suggestions and tips would be highly appreciated! Thanks in advance guys!
